A look at the Uni-T UT210E
ledtester:
A couple of new vids by TheHWCave on using the internal trim pots to calibrate the meter:
UNI-T UT210E offset adjustment part 1: The theory behind it

Be sure to check the video notes for useful links.

I just received my UT210E "Limited Edition" from Bangood. The "limitation" is in the fact that, apparently, they forgot to populate a whole bunch of capacitors, see the attached picture.
Of course, I also bought a chip clip to modify the EEPROM using TL866II+, which works perfect for reading, so far I haven't tried writing the EEPROM. I carefully selected 24LC02 from the TL866II+'s list of devices that provides 3.3V supply voltage, that's to protect the main chip which goes to 3.6V max. My instrument has the DM1106 chip, which, I understand, supports up to 10000 counts.
Now I have a lot of reading to do but please forgive me if I want to take a shortcut. Is there a reply with "the best EEPROM" changes for this chip? I found minhtri0405's reply # 681. Is there another page I should go straight to, before I start exploring the entire thread?
Cheers,
Miti

For those that want to take the easy route use this script to modify the
memory dump: https://github.com/mkrupcale/ut210e
It properly handles the new chips 9999 count. Only thing missing is the
transposing of the DC/AC modes.

I've also (totally independent from @galileo, as it often happens) created an editor for UT210E EEPROM :) It's a single HTML page with embedded JavaScript, no server needed. Tested in Chrome, but it seems to work in Firefox, too.
Please open an GitHub issue, submit a Pull Request (or just post a comment here) if you notice any error or have knowledge on the meaning of any of the unsupported ranges.
