A look at the Uni-T UT210E

<< < (177/177)

cybermaus:
Apologies if this was mentioned before in this very long post.

I have a UT210E, and it has a DM1106EN chip
But I have had it for a very long time. Maybe since 2015 or so, so it may be one of the first ones. PCB reads "UT210E Rev.1"

I hate the backlight going off too soon, and always having to move it to DC, so finding this tweak seems useful. And I had all the stuff like CH304 and clamp already in a drawer, so I thought I give it a try.
Using this video and this specific post as a guideline.

And it all went very well. EXCEPT.... The content of my EEPROM is SOOO much different then the examples shown. None of the BEFORE values in the aforementioned post match.
So I do not dare to make the changes

Any suggestions?


Edit: anyone know how to link a YT video without it immediatly expanding and taking up all space?)

Edit2: Figured it out. Bad USB cable (too long for the CH304, erratic results)
When I plugged the CH304 directly into the laptop, it went correct the first time, all values as expected, all mods worked. (well, I did no test 1000 Amps yet)

Indeed, thanks.

Am I right in thinking this CPC/Farnell TENMA 72-2985 appears to be a UL tested, certified version of the UNI-T UT210E?

Sure looks like it. Mind you, legal mumbo jumbo not being my forté: Does "conforms to UL" mean the same as "UL certified"
I once had a discussion about IEC-61131, where a device I helped designing "conformed to IEC-61131", but it was never send for certification.
