    I'm a retired Occupational Therapist (on the wrong side of 70 yrs), just getting back into various hobbies that interested me when I was a youngster, and know little about electrical/electronic testing of equipment. I'm very glad I subscribed to your fascinating channel and see the scientific approach you follow in all your tests. I think for anyone wanting to get really useful, accurate and practical information about these products, your channel is a "must subscribe" situation. You have manufactured a unique series ot test equipment, and follow a specific procedure for testing all the products. It's quite an eye opener, as I'm aware of all the effort that goes into this type of video production. Thanks for all your skill in videography, editing and the knowledge that you so freely share with such enthusiasm.

    I had that same issue with my EEVBlog BM235 where the jack was off center. However a lot more than your video. It was basically covered by the case on one side. Required a lot of force to plug the probes in. Seeing your video explains how that happened during assembly!
    Ended up getting a deal on a 87V on eBay.

    The "Interference" you indicated, I have more information on that! Dave Jones reviewed a "bad" unit sent in by an owner of this meter. That very inductor part was broken! Good review; above and beyond what most do -- great job! BTW, for 'a few dollars more', you can get the BM257S, with better specs and more features.

      I bought one of these from Dave at end of Jan 2018. Looking at mine just now, the L3 part has been moved down and to the left instead of sitting right next to L2. Mine doesn't have any part of the screw post cut away as I guess with the component moved there is no physical interference anymore.

    Thanks for these in-depth reviews. Based on these, while I like the BM235, it lacks a scale display and AC/DC are combined. So, I decided on the BM257s and I am very happy with it. My line of work and my hobby (both dealing with arcade games/pinball), won't have me sending 20KV into the meter, but it is nice knowing that the Brymens are solid and accurate. It's fast enough to detect fluctuating 5VDC voltage from a game's power supply, identifying its mystery problem where my old meter showed steady voltage.
    You're helping a lot of people make educated decisions when buying these tools. Thanks!

    This is incredible work you're doing. This is far and away some of the most rigorous electrical testing I have seen done on multimeters. I'm really glad that I stumbled on your channel.
    BTW, if you ever want some fodder for your transient generator, I have a handful of junky meters I could send you. Maybe you're aiming to look only at "real" meters, but mine are mostly off-brand hardware store buys and a couple "Ebay Specials," seeing as I'm actually still using my good meters.

    • @joesmith-je3tq
      @joesmith-je3tq  8 років тому +15

      Thanks. I'm glad you are enjoying them. I think the biggest reasons you don't see more testing on meters is cost and time. When you watch this video, realize the transient generators and high voltage probes are all home made. Price out a real generator. Not to mention the hazards if someone went with a purchased unit. Then there is the cost of the meters. But the worst part is the time. If you look at the clock on the transient generator, you can see how long these tests take to run. I do it out of my own interest. I appreciate your offer to provide some meters for testing. I have ran all sorts of meters. That analog meter was $15 and was as off brand as they come.

    Nice review, I always wondered if it would pass you transient generator testing. Its good to see it passed. I also really like this meter, it's become one of my favorites.
    One feature not mentioned is the 235 will read ACV variable frequency drives, it has a mode selector specifically for this in the AC voltage reading. Not a common thing to run across in a home hobby, but I did recently run across something I was repairing and it was the only meter to take an accurate reading. I personally never thought I would use it, but It worked good and I was glad I had it.
    The low pass filter is a nice feature that can be used to discharge caps and get more accurate readings in some situations when taking a reading on a variable frequency drive or composite sine waves created by inverters.
    The auto mode works good detecting AC or DC (also the low pass filter mode) but you loose resolution when using the auto mode.
    I also wish it read higher frequencies and had the ability to read duty cycle. Besides that it's a great meter.
    P.S. It did survive the electric ⚡️ fly swatter test at 2.3KV DC.

    Thank you very much for your review. I have a Fluke 12, two Fluke 117's (home and work) but wanted a meter that did uA for electronics. The easy choice was a 87V but that would take a bite out of my fun money. I homed in on the BM235 as a reasonable unit for the money. That other Brymen sure looked interesting but I couldn't find it in USA. Maybe if I had looked a bit harder. Anyway, you made me feel like buying one is a good choice for my current level of need and experience. Thank you again.

    Only half way through the video but wanted to mention the non-pop parts have to do with three different models being used for these PCB's. You will see 231,233,235 with pads next to it in each PCB. And they drop solder in what the one is populated for. I don't have the cutout on the back screw post, this might also be because they changed the components in version two (white box) and some other slight changes to stop the LCD light sound on some of the original versions. The new components might be thicker and they had to cut the post to adapt to this thicker parts? Just my guess.

    • @joesmith-je3tq
      @joesmith-je3tq  8 років тому

      Hey Scott. I almost called you out on the difference between a cap and a bead. lol. As I mentioned, the two extra clamps are not routed. The question then is if you have the other models and have looked at how they are populated. Sounds like you have. I am interested in knowing then which version of the meter is using the MOVs? I measured the stack up for the case and PCB as well as took some pictures of mine. These are up on the EEVBLOG site if you want to have a look.We need to revamp the flyswatter test. Maybe parallel / series a few hundred of them! lol.

    • @GadgetReviewVideos
      @GadgetReviewVideos 8 років тому

      Sorry, I don't have the other meters, this is my first Brymen. It's just a guess like the cheaper flukes are the same PCB for 4 or 6 different meters just with missing parts. AVE did a tear down on one and I noticed it was the same as others flukes but missing a DAC and IC for RMS, also the temp reading and other features worked but didn't have a button pad or a whole for the button on the front of the case. I just did a google image search for thenother models to do side by side of the PCB boards.
      I own two fly swatter, so we have three. Might be easier to remove flyback circuits from old tube televisions. Or I have a box of ignition coils with about 25 of them, lol.

    • @joesmith-je3tq

      Ok, I thought with you pointing out that the non-pop parts have to do with the different models, that you knew the details about the MOVs that were a no pop on the 235. At 2.5KV DC, you could use it to charge a bank like I did with the cap when I took out the UT90A. I have not had mine apart to measure the size of the filter cap.

  • @bvqbvq
    @bvqbvq 7 років тому +1

    Hi Joe.An excellent video.
    I am interested in the over-voltage testing of multimeters to show compliance with the Cat standards. IEC61010-1 lists the over-voltage test limits required depending on the maximum working voltage being measured. So for example if a meter is marked as 600V Cat III then it must be able to tolerate 3.4kV for 60 seconds.
    The front end protection on most meters claiming a Cat level are very similar to the the Brymen circuit that you have sketched out in the video. Whilst I can see how the circuit protects against short duration surges I cannot see how it is designed to protect against longer duration over-voltages.
    If one imagines that a 3.4kV over-voltage appears across the meter input then the PTC will heat up until it drops most of the voltage, will it not then breakdown with about 1.4kV across it resulting in a large power dissipation in the first 1k resistor? Is this 1k resistor a fusible type that is designed to go open circuit in such situations?
    I have not seen any of these over-voltage tests presented online, it would be interesting to see how various meters perform.

    • @joesmith-je3tq
      @joesmith-je3tq  7 років тому +1

      I have heard of people attempting to directly measure the output of a MOT with their handheld. You need to take a step back and just think about what you are suggesting. Does this even make sense to you? I would read how they define Working Voltage. Make sure you read Note 1. Maybe Annex E. I am not sure where the 60 seconds came from. Maybe you could provide the sections you are referring to.

    • @bvqbvq
      @bvqbvq 7 років тому

      I think I have misunderstood the standard. I was looking at the test voltages in Annex K and thinking that these were differential voltages across the input of the meter. I think that these are actually a test of the insulation and therefore not a differential test.
      The 60 seconds is mentioned in K.1.3.1 & Table K.8
      That being the case, what is the purpose of the PTC in the protection circuit? It is never going to respond quickly enough to transients.
      The other thing that I don't understand is how some meters manage such impressive ACV bandwidth. I have a Fluke 287 here which is almost flat to 1MHz! How is this possible when the input resistance is a minimum of 10M? Even a few pF will result in a low cut-off. The front end doesn't appear to be compensated like scope inputs and putting a high voltage cap across the 10M seems like a bad idea.

    • @joesmith-je3tq
      @joesmith-je3tq  7 років тому +1

      I can't really comment on the whys of meter designs. 61010 is a safety standard and if we assume the meter is not required to survive then why have a PTC or anything else as long as it does not make an unsafe condition? Of course if your products are always being returned from being damaged, as a supplier maybe you need to address it? In the end, I assume if a company certifies and to what standards, how much protection they add, it all boils down to how to make money.
      If you watched the video I made where I look at making the UT61E more robust, you may find your answer. If not:

The absorber will handle about 100 Watts. There is a ground shaft to align everything when installing a motor. With the ceramic bearings, I could do pulls well above 20K RPM with it but proper alignment was very important!

      yes i agree they were great to deal with, they even helped me yell at TME because they stopped responding to me. Eventually I just sent the same email to every contact on TME website until they just gave me some story about my meter being damaged in shipping and refunded me. I just didn't have a good experience with TME . I considered Greenlee(looks like same meter( but the price was much higher.

Just go to the main page and select the Motorcycle playlist. There are three different videos for automotive meters shown. You would need to watch and decide if one of them suits your needs.

I don't know if thats a new feature of the D firmware that mine has or is just a undocumented feature, but thought i would mention it.

The next time i tried it, it was nice and loud with the backlight still flashing. Since then, I've tried to turn it back down again and i cant figure out how to do it, so maybe Dave can explain it.

    01:30 : One thing I fail to understand is that the protection circuit you're demonstrating here appears to be common in other meters that you've showcased as well yet it's only in this case that it is located in a separate board and, I don't see why every manufacturer doesn't just make this part as a separate piece that is a common for each entire range of meters. Even better, it could be sourced as an individual part from an OEM, just like it is done with LCDs.
    I can understand that the economies of scale may dictate a single board instead of two or more and the extra costs these entail. I can't understand it, however, when this circuit (or what could be a part of it) maybe a safety liability.
    06:05 - 06:10 : Do these clamps need to be close to the ICs they're protecting or can they be shifted to the input protection circuit? Is the track lead inductance a determining factor in their placement?
    06:52 - 07:02 : I bet this can be easily achieved using a template during hand assembly. Does the tinned track on the back of the mini board have to be created by hand or are there robots that can do the tinning? It doesn't look as if it's been done by hand but I really can't tell.

      I can't say I know much about the business model of such specialised companies - it's a complete mystery to me and I'm quite happy with it staying that way - but I suspect the clientele of companies such as Fluke, Gossen, Tektronix etc. is predominantly comprised of professionals and not hobbyists.
      Probably every aspect of designing such instruments is a specialised field even among EE professionals - as with most fields of enterprise nowadays. In addition, there are the secrets of the trade to compound what is already a complicated enough matter to those on the outside. I am certainly not expecting any of these active professional to appear out of the blue and start answering design questions regarding a specific model in a public forum - I would expect that might be quite contrary to their contractual obligations or professional ethics. By posting questions or points on aspects that tickle my interest I'm hoping to generate a discussion or invite qualified responses from whoever might share a similar interest or has something to add that might aid understanding. Everyone's level of expertise is quite different of course.

      a-ha! Thanks for the link - I hadn't realised you had a dedicated topic on EEVblog. I don't frequent EEVblog much but maybe I should. I'll definitely check the topic you''ve created.
      I've been hopping around your videos on different meters but haven't had the patience to go through one of your longer series on a single meter yet. The reason is probably that I'm interested primarily in certain tests such as ESD,, RMS measurement bandwidth, etc. more than others (e.g. functional testing). Now, if I had my eyes set on a particular meter, it would be a different story of course. What has impressed me watching your videos, however, is that there is no single meter you've reviewed that is without drawbacks - regardless of price. It's more that some are better than others in certain respects.
      As I've only found your channel, the wealth of information is quite overwhelming and I ought to pace myself. I'm interested in the capabilities some of the more advanced meters you're testing have to offer especially with some which could be used as bench top replacements. I can't bring myself to fork out the cash one of these cost - I just don't really need these capabilities, I just find them interesting. Then again you never know what I might find on ebay in a couple of years. In any case, it's good to have some idea of what lies under the bonnet. I suppose if I ever decide to go for one of those, I'll be buying it with my eyes open. I know very little about the workings of digital meters and these videos have certainly widened my perspective on their limitations.
      But you're right in that the yt channels are not the proper place to have discussions anyway - the format is not ideal for this use for a start.
