- Siglent updated their user calibration process in firmware V3.01.01.12R1, I show how to calibrate a Siglent Multimeter !
Siglent watched my previous videos performing the original user calibration process, they listened to my feedback about a better way of doing it and they actually did it ! WELL DONE Siglent !

That's awesome 👍
Last year I wrote Siglent Support, because the User Calibration on the SDM3055 was faulty. I figured out that the SDM3055 calculated the Values in the mV Range wrong. And the R-Range were impossible to calibrate.
Coming week I will take the SDM to my work an try to calibrate it with an 8.5 Digit Fluke.
Geez, you must have South Island's most sophisticated lab.
Thank you very much for your involvement 👍
Thanks Scott, yes much better this way!.. thanks for the update
Thanks for the important information!
Being a newbie, how often should the unit be calibrated? Also, if I do not have another unit to use (like you are doing there), am I dead in the water? I would rather do this myself and not have to send in the unit to pay for calibrating. Thank you for your time!
So if you have to use another digital multimeter to calibrate the one that you have, how do you know the other meter is ok itself?? If it wasn't in great calibration itself, then a waste?? Sorry for the novice perspective/newbie perspective. It was just something I was wondering. Your efforts here are indeed brilliant, though.
@@jamesdonaldson7546 I am comparing a 6.5 digit meter to a 8.5 digit, so 2 orders of magnitude greater resolution. The 8.5 digit uses artifact calibration based on a 10V reference, which I do have calibration data for, also this is all being generated by a Datron 4700 calibrator who’s output has been verified against other standards I have, so I can have a high confidence level in the calibrator and the 8.5 digit meter accuracy for the purpose of adjusting a 6.5 digit meter.
This is great news. I presume the factory calibration still remain stored in case if we mess it all up?
Yes, you can always revert back to the factory cal, in fact if you need to call more than once you should do it based on the factory cal, I found with the previous method that if you did it from the user cal it did it wrong, so best to do it from factory cal.
My SDM3045 is out of spec by a few mv, siglent wants 190 to do a cal/adjust on my sdm3045 that only costs 400! How are you deriving accurate voltages at all those different and specific ranges the meter lists? Most voltages standards are like 5 or 10 volts only. Are you just transferring the readings from the higher accuracy Advantest meter? I would like to be able to do my own cals
@@robertgast5953 I have a Datron 4700 calibrator, I use that to generate the voltages, in this video I have the 8.5 digit meter there for reference.
The Rigol PSU's have a similar feature, which I really like. Well it does on the Rigol DP832 anyway, so I guess they do it on others too. Manual data point entry is possible, but I don't run this manually on my box. I use PyCharm software and a script (thanks EEVBlog!) that reads the info from my Keysight 34465A and programmatically runs through the cal' sequence. Does the Siglant have this feature too, i.e. you can use 3rd party, or even Siglant software (?) to automate a calibration sequence?
There is a calibration script from Siglent which is based on using a fluke calibrator for automated calibration.
What no caps involved at all.
Is which model of this Meter do you recommend getting ... Also will this display On pc Live readings on the pc ?
It depends on how much precision you need, the 3045X is probably enough for most people, but the 3055 has some improvements, and the 3065X has a better reference and some extra features.
I really don't see what is the need for those meters they do nothing for you. Is just a vanity on the bench. Can't even test transistor with them, a $20 bucks tester and bench Brew circuits that cost 0 will do more for you
If you need to check the accuracy of a lower digit count meter, you need a higher digit count meter… I DO use all the digits when working on higher end test gear, it’s use isn’t for hobbyists where 3 digits is good enough, if you want to test transistors use a transistor tester.
