Brymen BM786 DMM Part 4, Conclusion
Вставка
- Опубліковано 25 гру 2020
- In this final episode we have a look inside the BM786. We also perform several potentially destructive tests. Is the new Brymen series of meters robust? Watch and find out.
You may notice that parts of the video may seem the video was shot out of order or that I may have incorrectly stated what the current status of the meter was. These are not mistakes. While making this videos I was providing feedback to Brymen which drove a few additional changes. Some parts of the video were recreated using updated components in order to demonstrate how the released product would behave.

You put far more work into your videos than any other EE youtuber I've seen. What a treasure
Thank you. Yes, it takes some time but I'm guessing the few of you that come here are not interested in unboxing, basic videos. I know I'm not. Have a Merry Christmas.
I agree. This is pure, no BS engineering. Sets the standard, really. Thank you for all your work, Joe! It is very much appreciated.
Thanks Joe, awesome comprehensive work as usual. For those interested in availability I've already paid for my stock of BM786's but still don't have an exact ETA, but it should be fairly imminent. But I am taking a break in mid Jan, so not sure if I'll have them and be able to ship any before I leave.
Glad to do it and with Brymen stepping up, it made it all the more worth it. I was hoping you would have settled on a price before making this last video. I left the spreadsheet blank for now and will update it once you lock it down.
I just want to say Joe , THANK YOU for making these detailed videos helping the average consumer to make decisions. I have also found EEVBlog through your channel. Cheers.
Thanks for the hard work Joe always a pleasure learning with you.
You're welcome. Have a Merry Christmas.
This was excellent. It was full of great information and results and not too much time on the tests. Watching this was 1;40 of my time well spent. I truly appreciate the weeks of time it took you to conduct and film the tests and the hours of editing.
Thank You!
Thank you. I'm glad you enjoyed it.
Thank you for all your hard work over the last year. Wishing you and your family a HAPPY SAFE AN PROSPEROUS NEW YEAR
It was good to end the year with a robust meter. Have a happy new year as well.
Thank you very much for the review. I immediately ordered in 07.01.2021 the model 785 , and already arrived . I am very pleased. And big thanks to Welectron .
Thank you very much for your work. It is so valuable. Very very superior quality review of the meter.
Some say fluke 87-V is super man of multimeters, now it is replaced by some other meters, but your are the best multimeter guide i ever known, and you will never be replaced by someone.
Thanks.
Thanks for the video Joe. Excellent as always.
You're welcome. Have a Merry Christmas.
I cant wait to see your review of the bm789👍
Your reviews are on another level.
Especially your talent to find quirks in multimeters is impressive.
It's very nice to see Brymen actually using that information, that's good business practice and gives confidence to customers (this one at least😁).
I've been working on improving software for the VNAs and a few other products but plan to run that meter soon.
After watching these extensive tests i ended up buying this meter, really fantastic thankyou
Glad you found it helpful.
Thanks! I've been waiting for this episode.
So have I!! Merry Christmas.
I wish I could give your videos two thumbs up, Joe! Love your work. Thanks!
Thanks.
Seasons greetings to you and your Family Joe...great conclusions to you multi part installment test on this new Brymen multimeter...looking forward to Brymen releasing the final version...👍🏼🙂
Dave has it listed and people have started to receive theirs. I haven't seen a lot of feedback yet. It does appear that the version they shipped is what I had tested last.
@@joesmith-je3tq That sounds great! Maybe some of your subscribers will report on how their particular units are performing....looking forward to some feed back from them...👊🏽🙂
Well, that was a test more than thorouhgly done! 🤓
I appreciate that.
Happy New Year. 🎆🎇💥
Thanks. Have a Happy New Year!
Nice work Joe!
Thanks and Merry Christmas. Looking forward to seeing you push that Testo meter.
47:23 Stopping the test because dinner takes precedence? No dedication at all... :D :D :D
Seriously, though, this is great stuff as always. You're a real treasure, Joe. Here's hoping you have an awesome year, and that your Christmas and New Years Day were great fun!
Thanks.
Thanks for your effort in reviewing brymen bm786, it seem like a robust multimeter. I really like the visual indication for continuity test and audible indication for diode test, this features changed my mind from brymen bm829 which I was planning to buy earlier next year.
It does seem solid. Not just that it handled the drops, chemicals and transients but that it's autorange now works so well. Merry Christmas.
@@joesmith-je3tqCould not agree more. After 15 minutes working with this meter it is hard to go back to others. Very good multimeter. Helped us to trace the major problem on one PCB and saved us from replacing this PCB at a cost of $1070 after 60 minutes within arrival. Very accurate.
Congratulations on your excellent DMM reviews, the knowledge you’re sharing is priceless. Have you ever considered reviewing FLIR branded multimeters? Greetings from Brazil.
I just ordered BM789, I hope it comes with the latest firmware 🤔 thanks for your hard work. You make a lot of life easier 👍
I hope your video for BM789 coming soon 🤞
I got my meter 😊 yesterday.
Same here. Got my from Welectron.
@@reveal1693 me too from the same website.
Merry christmas
Nice video thanks for posting
You're welcome. Have a Merry Christmas.
Good location for the batteries compartment. Actual feeling about this BM786 multimeter once you start regularly use it - rising with every measurement confidence in obtained results. Well thought after meter.
Really am glad Dave Jones went back with Brymen.
Those EUI's were kinda fancy but I'd rather have a Unity 139-C.
I know of 8 or so people who bought the UNI-T UT210E clamp meters all around the same time. So far, three have had switch failures. Mine has required cleaning already with minimal use as well. It's too bad that they don't improve their products. I would gladly pay double for a higher quality 210E. After looking at so many of their products, I have given up on the brand. Have a Merry Christmas.
@@joesmith-je3tq I gave up on UEI 25 years ago.
Happy holidays.
@@aurthorthing7403 After seeing that 121GW first hand, that doesn't surprise me one bit. If I had to choose between the 139 and 121, I would still go for the 121. RF link, higher res, multi-display..... If it was between the UNI-T UT181A and the 121GW, the choice gets a bit more difficult. I think I would go with the 181.
It is a different cattle of fish..this 139 meter. BM786 cost twice as much as UN-T139C but has ten times better functionality
@@joesmith-je3tq and you can get electrocuted while it lies to you and says there is zero voltage...
Love the comprehensive testing. Im thinking maybe you could take a look at the TES 2900 dmm. Specs looks good and made in taiwan like the Brymen.
Excelente trabajo Joe,tengo que reconocer que hay pocos cómo tu.
También hay que reconocer que Brymen ha hecho un gran trabajo y el tiempo cómo dicen algunos compañeros hara el resto.
Fluke, Hioki ,Agilent, son grandes competidores, pero Brymen en poco tiempo los alcanzara, sino lo ha hecho ya 😅.
Un saludo 👋.
At least from looking for products for electronics market, Brymen has already surpassed them.
Thanks Joe, grate job.
It seems that BM780 series is best choice in 200$ class. I'm going to buy BM789.
I've been using the BM789 over the last few months. With the last changes, mine now has the latest firmware and performs really well. Have a Merry Christmas.
@@joesmith-je3tq Often I must observe low voltage trend in about 250 mV so I need fast, reliable readings in 1 mV resolution at least. Could you please show in next movie update rate in mV range?
@@Pampali You would need to spend some time putting together some sort of test plan (procedure) or I doubt I would show you what you want to see. The manual states 5 readings per second nominal and 0.03% + 2 counts for the 600mVDC range. For 600mVAC, they provide accuracy depending on the frequency. One thing you will need to consider it that the meters I have may no longer be in calibration. As Brymen has mentioned, they may require alignment after replacing the ICs. Give it some thought and explain in detail exactly what you want to see. You could join the EEVblog and post in that long standing thread (link in the description).
@@joesmith-je3tq Is there a way to identify the firmware? i bought mine this week, and have no idea if it has issues similar to what you find with the 786...
@@nemaon The meters were released with the new firmware.
Hi Joe, I watch all your videos patiently in the evening when nothing else to do. I have been following the multimeter scene recently, there is a lot of buzz around a meter Habotest HT118A (dual-display auto-ranging 6k count). It is also sold under various brand names. This meter is easily available on Amazon and other local websites .. maybe you'd want to have a look at this. For the price, features look unbeatable but I am sure they must have cut corners.
It sounds like the HT118A sounds would be a great fit for you. It looks like several people have reviewed it. Try the YT search. If you've been watching, you know this channel looks at how robust these meters are. You should also have a pretty good idea how my buying one would end.
Thanks Joe for the reviews and testing. I just ordered a 786, and hope it is as good as the ones you tested.
Enjoy your new meter.
Thanks for the extensive series on the 786 and 869, your help is greatly appreciated.
Was wondering, is this dmm your personal choice for anything under 500usd? I’m considering one for bench use for electronics projects.
Thanks in advance
The BM869s is still my favorite of all the meters I have looked at. I also like the vintage Fluke 189 but the Brymen has a few features that I like that the Fluke doesn't.
@@joesmith-je3tq Gotcha 👌 We have a winner then 😊 Many thanks!
@@deeptechh Well, I would say I have a winner which is what you asked. Now as far as yourself, hard to say. Maybe something else would be far better suited. Learn to make your own choices.
I searched to buy my first DMM and ended up ordering the 789. I wanted to order the 786 to support Dave first but the difference in price between the two is very minimal over here, so i opted for the 789. Anyway thanks for the great reviews.
@Sando Kan Hi Sando,
I bought mine from welectron, the moment I ordered it they where in stock.
@Sando Kan No problem and good luck with the search.
That battery life indicator ?? even in case of nuclear attack you get 4 minutes warning. I just wish Bryman would distribute there stuff more widely they never really disappoint.
I think you are missing a few important details. First is a time scale. These tests take a lot of time to run. That minute of life cycle testing for example was 60 hours of time. These transient tests are also sped up a lot. We can see that the battery indicator was coming on long before I changed them but would turn back off. From the battery life testing, we also see the meter has different power requirements depending on the mode it is in. This is typical for all meters. As I mentioned during the video, I am testing with batteries that were long ago discarded an will no longer hold a charge. I use these to get some idea how the meters will behave with under a worse case condition. I doubt these follow a typical discharge curve for NiMH. Hope that helps clear things up for you. Have a Merry Christmas.
After all of this excellent information on this multimeter are the changes that you recommended to the manufacture updated and what is the latest model # that is available for purchase and where? Thanks for preventing buyers remorse.
If you follow the forums Dave posted there was another update to the BM786 firmware, so it is now a later revision that what I have shown. As far as I know, Dave has an exclusive for this particular model. You would need to check his store or ask him if they have other distributors.
I replaced my Victor VC921 after giving my other one away to check battery voltage. You maybe over pocket meters but if you do anything with them again the new one came with a orange dial so I looked inside. It has a different chip, layed out different and more parts inside. Three capacitors by the positive lead for sure. Board is vc921 vo.7 2018.08.29
Thanks for the update.
VC921 in frequency mode max voltage is 40V maximum by the way..
Great review Joe ! Awaiting to buy one of this from Dave...
Let us know what you think of it after to have had it for a while.
Dear Joe, i'm interested of the BM789. I wonder if a review is planned for soon...
I have the meter but have been working on other projects.
@@joesmith-je3tq So i will keep an eye on your channel ;)
Hi Joe! Any suggestions on affordable DMM's that measure True RMS voltage with accuracy up to ~20khz? Application is measuring pro audio amplifier outputs with 6db crest factor band limited pink noise source. Max upper band 5khz -20Khz (though frequencies above 10khz are insignificant).
Would be great if you or Dave at EEVblog could do some testing specifically on True RMS voltage performance of affordable meters. Tests & factory specs pertaining to True RMS voltage capabilities seem to be almost non-existent.
So far the only contender I know of is the UT61E (Tested to 30khz triangle wave in Dave's Sub $100 meter shootout).
I'm not much of an audio buff and do not normally recommend meters. However, I am surprised you are not using something other than a DMM. Something like my old HP3589A may provide more useful information. Guessing there are other options when you start working at these low frequencies.
That network analyzer is spec'ed at 10Hz to 150MHz.
The BMH-02 Magnetic Hanger appears to have damaged the beeper in my BM789, are you able to confirm it affects the BM786 also? With the magnet attached the beeper is almost completely inaudible
Yes it does, on every one.
I just sent them a note. Good find.
Great video. Are these meters the same as the Greenlee meters just rebranded. Thanks.
Greenlee is a Brymen distributor but I am not sure if they offer any of the BM78x series.
@@joesmith-je3tq Thanks Joe cheers 🍻 Just been watching a review on the Hioki DT 4252. It was quite impressive but the reviewer still likes the Brymen
Which one is the best multimeter for everything. ( home, industrial, electricians and for electrical users)
It's a very common question covered in the FAQ. I do not make recommendations nor am I trying to sell meters. Maybe rather than double posting, read the FAQ.
Like the thiner fuse format for the miliamp range, it leaves more space available for other stuff and they don't cost a fortune like the fatter ones. Looks like maybe a SIBA 7017240 series.. 1000v/30KA. An adaptor (like two brass caps) would not be too difficult to make so to use them in the fatter format meters like Flukes since they are just a little bit shorter too.
Yes, that is a SIBA 7017240.0,4 30kA AC/DC 1000V. Datasheet may be found here:
www.siba-fuses.com/front_content.php?idart=117&nummer=7017240.0,4
I've seen some pretty crazy things with the fuses. People soldering wire to them seems common. So is using the wrong fuse. We have also seen people post some of the damage. It's pretty rare I will use a meter to measure current. I've blown more fuses making these videos over the last few years than I have in my entire life. Have a Merry Christmas.
@@joesmith-je3tq Merry Christmas!
Hi Joe, my Brymen869s gave suddenly random value's when I was measuring 3.3V on arduino. I have changed the battery, checked the fuses. On AC, DC Ohms, etc. the measure is random and the horizontal bar is jumping. Do you have any idea what's wrong with this instrument? It never fell down nor overloaded. Thanks for your advice.
Is the voltage you are measuring stable? Did you check it with a scope?
@@joesmith-je3tq yes, with my old Fluke it is 3,3V. Measure diode and Cap with Brymen looks good. Ampere not tested all AC and DC is random and never zero, even when short the input. Cables are good. If I measure an 1.5V battery, it jumps around 0.8V (looks like the half of the reel value), if change the polarity it jump around 0V be never goes negative. Do you have some schema? Maybe someting wrong in the power supply from the Brymen.
@@lucvanhove9639 I don't have anything beyond the what I had reversed engineered for the video. How old is the meter? HAve you contacted Brymen about having it returned under warranty?
@@joesmith-je3tq The meter is from april 2018. I ask info to the shop but no answer till now. The meter cost 218 Euro, if I send it back, one working hour and calibration, better buy new one. But before this, I like to measure the power supply lines insite the meter. It is very strange that the meter getting bad just on the workbench. The 9V battery was 4.5V, but change battery didn't solve the problem. No negative results in DC mode and it measure the half of the real value. Open leads show random value, not zero. If I find the problem, I will tell you and send a picture. Thanks a lot Joe. 👍
@@lucvanhove9639 That's too bad. I doubt there is little I can do as I don't have the meter in front of me. Wonder what caused it to fail. The claim is it was just sitting on the bench with a dead battery. You replaced the battery and it it stopped working. That's really odd. I have abused the ones I have far beyond what I would normally expect and they are still running fine.
Nice magnet thingity setup right there
Brymen seems to produce some awesome meters. I am thinking of buying the BM867s, i like the idea of having a dual display, the price difference between the bm867s and bm869s seems a bit much, or am I mistaken?
Not sure what you are asking. What you find is a bit much is really your own perspective. The channels isn't here to help you come to grips with your purchases. Consider that I think I paid around $230 for the BM869s back in 2016. It's coming up on 5 years and still in use today. I paid more for that Fluke 87V which never sees any use. On the high end of handhelds, the Gossen Ultra tops the list. That meter with tax is close to $1000. On the other end of the spectrum, we have the free meters from HF. All of these were bought out of pocket to run these tests on with no asking for donations, ads or other compensation. I suggest you actually Read the manuals, understand what it is you are reading, ask questions before you spend any money. Make sure you buy a product that meets your needs.
@@joesmith-je3tq You are absolutely right, much is a subjective thing. You and your channel are a great resource of information. I have seen numerous of your videos about the Bm869s, this is exactly why I looked into the bm86x series. So your channel is inadvertently helping for me to come to grips with my future purchase. I did read the manual, i did not notice the 867 had zero thermocouple inputs however which is a shame(I thought it had 1). I honestly don't know if I need the additional True RMS frequency. I guess that is why I am unsure. How much I hate buying stuff.
@@Rashombo If it's just for your own hobby, it doesn't cost anything to think about it. You don't want to be the person asking me how do I modify this meter I just bought to make it do what I want. If you don't have a need and just want a new meter, I would wait.
awesome videos. can you please get a BM789 and do a review and compare with BM869s? thanks
What would you like to see beyond what I typically show?
@@joesmith-je3tq nothing more, your reviews are perfect but I have not seen a review of BM789 yet. I am undecided between getting a 789 or 869s. I was hoping I can seen them side by side in your hands!
@@amirb715 If you watched this video, you know I am planning to run the 789 next. However, as I have stated, because I have changed ICs, the meter may no longer be in calibration.
Whats the EF detection like on this meter?
Outside of what I showed in the video, I'm not sure what you are asking. Did you watch it?
@@joesmith-je3tq Apologies I somehow missed it on the first watch, thankyou for the reply
re 45:10
1. How exactly do you upgrade the firmware
I have a BM786
and i think i'm doing this correctly
PRESS THE DELTA BUTTON UPON STARTUP TO OBTAIN FIRMWARE VERSION

2. Where do you obtain the latest firmware versions from ?

thank you , will look through it later on,
appreciate your time
@@joesmith-je3tq
ok , i watched the video
so.. You're basically saying
1. it's robust as it is
2. there is no downloadable firmware as such
3. the way to update the firmware is to approach brymen directly and get them to send me an UPDATED I.C. with the new firmware
then i would have to desolder and swap it out manually
ok
CAN I ASK THIS
What firmware version is your BM786 that has the updated firmware ?
@@martinkuliza www.eevblog.com/forum/testgear/new-eevblog-bm786-multimeter/msg3400972/#msg3400972
@@joesmith-je3tq ok, thanks, i'll watch that
Which best multimeter 123 ?
The one you buy 321.
Do you think Brymen will apply the bm786 firmware updates to the bm789? I don't know about where you live, but once I account for shipping the bm789 from TME is only $15 more than the bm786 from Dave. It seems like a shame to not get the higher bandwidth and other features for only $15 more. I use dB on my old meters pretty often, so it seems like the right choice.
I know they have applied the same corrections to the 789, because I was testing them in parallel.
@@joesmith-je3tq thanks, very awesome as usual. Will you publish a video on the 789 soon? You seem very busy!
@@JamieTyson Hopefully over the the summer. The 789 is similar to the 786 and as I explained, I had been looking at it off camera. As I mentioned, according to Brymen, after swapping the IC, the meter may longer be in calibration. The two meters use the same front end and switch parts. So the review becomes less and less important as I am typically only concerned with how robust the meters are. What is it specifically that you are wanting to see?
@@joesmith-je3tq I was mostly curious because I intend to buy one and I enjoy your reviews. I have a Fluke 189 the gets carted from home to work, was thinking a newer meter with similar features would be nice. I'd miss the dual display of the 189. The bm869s is bigger than I'd like. If there is a particular thing I'd like to see it's how it reads dBv in the mV ac ranges. The Brymen spec lists a pretty high lower limit for the dB function; my ancient Fluke 8050a surprisingly beats many newer meters for that sort of thing. I have a specific work application where it's helpful, so I'd appreciate a look into that if you ever have a chance. Thanks again Joe!
@@JamieTyson I wouldn't be surprised that you would find a bench meter having better specs than a typical handheld. I have been restoring a 40 year old Fluke 8506A thermal RMS meter. AC specs on that meter far exceed any other meter I have. Of course, that was reflected in the original prices of the meter. Normally beyond a few kHz, for AC measurement I will use a spectrum analyzer or scope. I have a very old HP 3589A that can be selected for 1M or 50ohms. Depending what you are trying to measure, I wonder if you would be better served getting something like this rather than wasting money on handheld meters. Don't get me wrong, the handhelds are alright for some things and after buying the 869s, I do use a few of them in my home lab but I have no illusion that they will replace my other equipment. What exactly are your requirements?
I wonder if Brymen are going to release a facelifted version of the 869s. I almost ordered the 869s when I found out that the 78x series (specifically the 789 model) would soon be available locally where I live. Price difference is negligible. Now I'm torn. I definitely like the dual display of the 869s and its better overall precision, but it is an older product. The usability features of the 76x series sound really interesting, particularly the auto-hold feature, also the battery type that it uses, the shorter (if we can trust the spec) duration of registered signal in the CREST mode, the increased 10/sec sampling rate in some modes, etc...
Does the 869s feel outdated? How do they both feel overall in regular daily use? I mean general responsiveness, usability; which of them you would wish to use more than the other to measure something (that both can measure equally well) if both are lying on the desk in front of you?
I have a BM789 and plan to make a review for it but have been working on other projects. I'm much more driven by data rather than feelings. I am currently working with a 40 year old Fluke that for the functions it has, would put any handheld meter I have to shame. But it's not nearly as feature rich as even the cheapest meters I have looked at. It sounds like you would like to see the 789 compared with the 869 though, and that is certainly something I can do.
@@joesmith-je3tq I guess, the look and feel would pretty much be identical between the 789 and 786, they only differ feature (and probably precision) wise, regarding which the choice can be based on the data sheet. Therefore it is more about series to series comparison in terms of what the new generation has to offer.
@@user-zc8sd8jx8s If you have followed the videos and threads, you may have seen both the 786 & 789 side-by-side. If not, yes they share common case components. Yes, the datasheet is really the place to look. You can form a matrix of features for each to help compare them. There have also been similar discussions on the EEVBLOG that you may want to read.
@@joesmith-je3tq Sure, I did check the data sheets and some threads on eevblog and other resources. If I decide to go with the 78x series, it will definitely be the 789, because our local dealer will most likely sell only this model of the entire 78x line. Besides, the price difference is not too big here, so I would get the top model anyway.
The question in my case is the choice between BM789 and BM869s. Features and precision aside (these I can look up in the data sheet), I wonder if there is any subjective difference ("feel") in using both. Hence my questions.
I have just come across your channel, there's a lot of useful information here! You sure did spend a massive amount of time creating this content. Sorry if I am asking something that has been covered already.
@@user-zc8sd8jx8s There is a FAQ sheet which covers the basic "what meter should I buy". Personally, that's not something I chime in on. The data I present may help you make a better choice. I get messages from beginners who will buy the BM869s that have not learned the basics. The most recent one, the person was returning the meter because they felt that it should read zero with no leads attached while they handle it. Buying decent equipment doesn't increase the buyer's education. My advice is spend the time up front to get the product you need. If you don't know what you need, figure that out first. Ask detailed questions before you purchase, not after. Don't ask me how to modify your meter after you made a wrong purchase.
Nice soldering tweezers - I'm very tempted now. Much easier than using air.
Joe, the Siemens, is 'Zimens' - they make fun of us for miss pronouncing: Seamens or Seemens, 'Das Boot' movie comes to mind. Same as Völkl skis is kind of a Foelkl (I have pair), V is like F.
Sugar is Zucker but Z is Tz.
I wouldn't waste your time being concerned about people making fun. You could try Google "siemens pronounce" and see what they have.
I do like these tweezers. I have a set of older ones but even with small tips, they are just too large for most of the work I do.
Does any brymen meter beep in diode mode like fluke
Don't think so. You can get a Habotest HT 108L that will for about 8 or 9 dollars US. I highly recommend it.
Just for you, I ran a test to see how the Fluke products I have behave and how this compares with them. you will find that information here: www.eevblog.com/forum/testgear/hear-kitty-kitty-kitty-nope-not-that-kind-of-cat/msg3388220/#msg3388220
Have a Merry Christmas.
@@joesmith-je3tq thanks, have the 869s and love it, just the lack of diode mode beep is why I have the fluke 87v and keysight meters, when repairing iPhone boards everyday it's a feature that's needed, when looking through a microscope you can't be looking at the meter every second
@@zxrjimmy1 Glad to help. If you look in the spreadsheet, there is some additional information for the diode check mode. You could compare your 87V against that data. There was a discussion about trying to make a heads up display for microscopes. Interesting idea.
@@joesmith-je3tq it's a serious time saver when finding short circuit on motherboard, there is times the diode mode on the 869s beats the 86v, its just the beep that needed for short circuit which is a life saver and time saver most importantly

Sorry to bother you and asking here like the village idiot, but I watched out all your excellent videos about this DMM and i can't figure out if the orange part of the BM786 housing is made some kind of grip rubber or if it's just a solid hard plastic. Seems to me that on the BM869s it is rubber but I'm not sure, could you please confirm that too?

Thank you so much on behalf of all non-English speakers. Really.
Hello from the USA. Where the BM869s has a rubber sleeve that will come off, these meters use an over mold design. Basically, the plastic case is covered with a layer of rubber but it is not meant to come off. It's similar to the Fluke 189.
@@joesmith-je3tq Very nice of you for your quick and kind answer. I was about to buy this poorely built in OWON device. Frankly, after watching your videos it definitely worths it raising the bet. Besides that I studied your spreadsheet very carefully for which you were kind enough to leave the link on I can't remember exactly which one of your numerous videos. And i noticed on it how your old RadioShack 2200087 flawlessly passed your crash tests ton time better than this OWON MU HA HA H A AH AHA AH A 😛! Oh Gosh lol! These Brymen's DMM look really fine in specs and money especially to people like me on a tight budget 😣. And I do not see the point at all for buying devices at say 75 € with postage and customs from China to regret it in less a year. Or even worse getting issues on it or whatever measurement errors and inaccuracies. It's certainly a good device in a certain range of requirements, but I'm still wary of those tiny weaks glass fuses 🙄☠. A few years ago I made a terrible mistake plugging the probes into the wrong connectors of my old cheap analog multimeter bought at the local tool store. And it blew up in my hands while measuring on the 220v 50Hz sector here in France 😱. Fortunately I always wear safety gloves when I work outside. But hey, pfiuuuuuuuu lol 🤕. You are truly doing a tremendously brilliant job and I would also like to congratulate you on the incredible quality of your work and the sum of your knowledge 🔬🥼🧪👨🔬. That's just damn amazing! 👏 Thank you very much once more and take great care of yourself! Because we are very probably several thousand (not to say millions lol? 😂) needing your talent and your knowledge so thank you Sir, Merci Monsieur ! 😎
@@MiettedeThonTomate That particular Radio Shack meter was impressive. I had another one that a friend gave me but it was so bad, I just returned it untested. If you decide to buy one of the Brymen products, let us know what you think of it after you have used it for a few months.
It would be a perfect general usage meter if they can make the fuse replaceable without completely take the meter apart.
At least you don't have to remove the PCB to get to the fuses like some of the meters I have looked at. Outside of making these reviews, it's rare I would ever take out a fuse in a handheld. Normally I use an external shunt or other type of sensor.
joe smith I also rarely blow a fuse in the multimeter, but I can’t count how many times I picked up a shared multimeter at work and find a blown fuse when trying to use the current range. Problem with shared equipment is that people who brakes it generally don’t care. Sometimes I even find non HRC fuses inside the meter because people didn’t have the knowledge to put proper fuses in. If my work run out of HRC fuses I’ll leave the meter without fuse until they got more fuses.
@@wadehsu2347 For work, you may be used to pulling the back cover, removing the 3(?) screws for the PCB and pulling out the entire assembly to get to the Fluke 87V's fuses. I understand that's the gold standard of meters! lol.
I have/had a cheap CEM meter I used for work. Someone borrowed it once that turned the knob past the dead stop. Mysterious blown fuses were not too bad. What finally ended it's life was someone had broke the input jacks. The plastic broke into several small bits.
joe smith that’s pretty rough. Your coworkers borrow your gear and broke them. Good thing work provides us Flukes so it is at least more robust against some of these abuse.
50000 full cycles is a lot. I figure I would get to such number in about 137 years of use.
It will depend on each persons use case. I talked about how Brymen qualifies their meters and the number of cycles they use during one of my videos.
I use an 867s and an 87V in my bench work and have really grown to like the 867s. The dual display is really nice for simple things such as measuring AC with a DC offset. No need to press a button or anything to switch between values and makes values clearly visible. To me, with prices being close, I lean towards the 867s, but being able to update the firmware is significant. Kinda hard to choose.
The only meter I have looked at that has user programmable firmware is the EEVBLOG 121GW. If you like reprogramming firmware, that meter is the ticket. If you actually want a robust, reliable meter, I would go with something else. There are lots to choose from.
Thanks Joe for all the great work!
From what I've read over on eevblog, turns out the firmware won't be upgradeable for meters already purchased. There isn't and sounds like there won't be a process for sending it in for an update.
@@czluver4338 No surprise.
hey, contury of origin Multimeter brymen
Taiwan. Try Google, you can get their address if you like.
4/1/2 price is too very very very high
Excellent job Joe, I’ve a question: I usually use continuity mode to troubleshoot motherboards, in normal multimeters beeps under
If you take the time to read the description, you will find a link to spreadsheet that contains all of the data I have collected. This include the data you are asking about.
