Thanks for this comparison. Seems to be very nice devices Siglent provides!
Thank you Markus, yes having them here on the desk is even better then the pictures...
When I retired from my electronics career 5 years ago I equipped my new test bench with all Siglent test instruments including scope, specA, 6.5 digit multimeter, power supply and sig gen. All equipment has been 100% and still in calibration. Very pleased with the quality versus price (and I tend to stay away from Chinese products), great products!
Hi, great to hear that, i am also very happy with all my Siglent equipment. enjoy the hobby!
Very nice to see them all side by side. Well worth waiting a day to see! Can’t wait to see any video content on these, you have time to do.
Thanks Brad.... trying to get a video about the scanner card, very interesting option-card
A great review and comparisation between the models.
Thank you!
Enjoyed your video about DMMs, digits, and counts previously and was pleasantly surprised to see this on. I own the SDM3045x and if fits my needs and pocketbook. Saved this video for future reference. Thanks!
Thanks! good you enjoyed it
Excellent review Tony... WELL DONE!!! 10/10
Thank you Dero!
Metrologist here, I've calibrated a few of these. They are really capable meters and generally perform well. However, Siglent refuses to share calibration adjustment information with anyone, including professional calibration labs. I've seen a few of these require adjustment within the first few years of ownership, and I think it's just bad business practice to intentionally withhold information that other manufacturers (Keysight/Keithley, Fluke, even BK Precision) would have no problem sharing. I hope they change their minds someday.
Hi, i think TheDevPom has a video about how to calibrate this meter via a custom calibration in the menu. hava a look at Scotts video
Nice review as always - keep up the great work!
Thank!, i like your work too!..
@@TonyAlbus Thank you sir!
Nice to see them together! Own a 3045x for a couple of years now! Still a happy user! For my hobby use the 3045 is more than enough. The futures are awesome!
Thanks Mario, yes i can imagine, all nice graphic options are in there too.
I wonder how many private rocket scientists there are who absolutely need 4 or 5 decimal places? This may be important in your professional life. Anyone who has the money can certainly afford to buy accuracy privately. But you shouldn't forget, what use are the best devices if they can't be calibrated regularly? But thanks anyway to Tony for his time to present the devices to us.
Thanks!
Thanks. To me the 3055 hits the sweet spot performance with price concerns. These are not cheap meters, that's for sure. I have had the 3055 for some years now.
Yes agree, the 3055 is the best choice of them. for a 6.5 i will have a Keithley or Keysight next time.
@@TonyAlbus - Nice to know that you agree. :)
Интересные модели. Спасибо за обзор
Не за что, You are Welcome!
Hello Tony and Followers:
The multimeters that samples are of good quality, and not long ago I need to buy one of this size and 6 and ½ digits, look at the keysight 3410a, it is pretty good, but its price is not very affordable, also look at the Siglent, of 6 ½ digits is not cheap either and of course it is not at HP / Agilent / Keysight. So opt for an agilent 34401a almost new with the original, newly calibrated tips, are found by prices from € 400 more or less and is a multimeter with very interesting options including an entrance impedance of more than 10 Gohm. The Siglent SDM3065 is a multimeter that is fine, but I do not think it is at the level of Agilent 34401a.
Good video sir.
Best regards.
Thank you Manuel! yes agree, but buying both new, the Siglent is half price and for what i have seen here in practice it is not bad at all, i can say it is good and well worth its price.
TNX !!!
Thanks for leaving a comment and watching!
I SERIOUSLY hate the non-suppressed leading zero.
Hi Steven, indeed something that should be fixable with firmware.. i will create a ticket for that at Siglent.
Hi Tony, thanks again for yet another interesting video. I am a bit suspicious how it is possible that the pc software displays not the exact same value as the meter it self. You can see that very clearly from 32:00 on. For example between 32.05 and 32:09 the pc shows 10.0005, but the meter display shows 10.0004. Not that i think that 100uA makes all the difference, but still it is quite odd why the displayed values differ for such a “long” time (~4s in this example). Any thoughts?
Thank you!, to be honest i did not spend much time investigating the software, maybe 5 mins. maybe some defaults are not good and i did not changes them
About that value, could be that the scan speed is different on the software then the meter maybe and on the meter it avarages out.
In comparison to ANY handheld, this multimeter shows EXACTLY HALF the resistance value measured in circuit.
Why is that ?
mainly the circuit it is in... i would think, in-circuit testing is always tricky
Can you please do a review of scanner card of siglent DSM3000 series
Hi Diablo, yes i will.. it is in the queue
@@TonyAlbus Thanks Tony
As I understand it, if you buy the 6.5 digit meter without the scanner card, you cannot add it afterwards. You need to buy the scanner card with the meter as a matched set. Can you confirm if this is correct.
Hi Sijmen, that would make sense, the device also says SDM3065X-SC in the front - SC(ScannerCard)
i heard from other brands that if you add the card later, it needs to be recalibrated, i don't expect it to be different here.
I just checked the website, i indeed don't see it as a separate option card. So i think you are correct. it is a matched set.
Respons from Siglent: The SDM3065X can’t be upgraded later.
I was looking for something a bit more accurate than my 4000 count handheld DMM. Oops ...I caught repackaged Amazon Warehouse special for the Siglent SDM3065X under $500. Overkill but ....
Hi, that is for sure a nice improvement!!
@@TonyAlbus If you still have one of them around ....
You should test the 2 wire and 4 wire resistance measurements using a sub ohm resistor.
To really push it you can "try" a standard Current Shunt, 10 Amp, 75 millivolt, 5% (75/10=7.5 milliohm)
More realistic results might be obtained with 0.5 or 0.25 ohm resistors.
Validate using a known current and the voltage drop across the resistor.
@@Bonjour-World Hi Lewis, i still have it, butr not using it, it is too sensitive to temp changes.
merhaba hocam. bir sorum var; hantek hdm3065 almayı düşünüyorum. fakat sizin videodan sonra kararsız kaldım. sizce hantek hdm3065 mi yoksa siglent sgm3065 mi? hangisi daha iyidir? ne önerirsiniz?
Hi, The Siglent is good, if you have a stable temprature in your lab. the Hantek i have not tested. i think both brands are good for the 5.5 digits, for 6.5 i would go for Agilent or Keithley.
@@TonyAlbus bugün siglent sdm3065x satın aldım. İlk dikkatimi çeken şu oldu; buzzer sesi çok çok az duyuluyor. bir de yavaş tepki veriyor. bu konu hakkında görüşleriniz nedir? firmware güncellemesi ile düzelebilen bir sorun mudur?
@@ergunguler3981 Hi, i don't remember mine beeps or not, usualy i switch it off. But maybe the tape is still on the buzzer. you can ask your store if they can check this for you and keep your warrenty. if it realy bothers you. i don't think it is a firmware thing, a buzeers is bizzing or not, don't think there is a volume.
Exactly what model of calibrator do you use?
Hi Marnix, i am using the LB02A from AliExpress, it is the first link in the description.
The trending on the pc software seems quite disappointing to me (33:00 onward). Why have a 5.5 or even have a 6.5 digit meter and then displaying no decimal digits at all on the charts (vertical on time chart and horizontal on histogram) on the pc software. These meters/software are on the market for several years now. Disappointing this has not been solved yet… I am in for one if these meters (most likely the sdm3055) but these kind of seemingly long time unsolved things hold me back.
Maybe it is a silly default, i did spend 5 mins only to check the software. i am looking for a 6.5 myself than i will play with it more. Stay tuned.
@@TonyAlbus Hi, looking forward to that review. 6.5 digits is nice, but the price difference between 5.5 and 6.5 is quite big and i don’t think i’ll need 6.5 resolution.
You work for Eleshop? Bought my 861DW from there :-)
Hi, I like to think i am independent so working 'WITH' not 'for'... but i do borrow from them, very friendly company i am also a happy customer.
@@TonyAlbus I see! They also tend to have good prices and also have friendly support. Sure a +1 from me. :-)
👍👍
Thank you!
Hello, congratulations. I was wondering, how old are you? Until what age can the electronics hobby be continued? Thanks.
Hi, i'am 52 and am hoping to continue 80+ as long as my eyes and brain work is should be fine. you be surprised how many old tech there are and still doing great work and having many many many years of experiance.
@@TonyAlbus Very good. Actually, I was born in 1970. I set up a home laboratory for myself. But I'm trying to learn everything from scratch. I hope it's not too late for this hobby for me.
@@Qazwsx-sr3yy '72 here .. Yeah no problem.. maybe some of my first videos will help you..the quality is not that good, but during the years its slowly getting better. but the information in still good. Enjoy the hobby!
Great review, how about calibration when needed
Good question. I have the service manual for the 3045, and the calibration is done via the LAN-connector and Python, NI-VISA, NI488.2 and Microsoft Office (!). If you want a copy send me a request at "post@multikontroll.no" and I will send you one. Siglent's calibration service in general is an open question.
Hi Mischa, i have not looked into that, i received then calibrated i guess. On Siglent website there are service manuals available for download.
Hi LA7YKA, i do have the sevicemanual, but i don't have the python scripts, do you have those?
@@TonyAlbus No. Perhaps Siglent can provide them?
@@la7yka Yes i will ask
