Absolutely BRILLIANT! What luck to stumble across this - I have the exact same clamp meter arriving from Amazon today, for a parasitic draw issue where the extra resolution will be really welcome. This hack addresses the two most common review complaints - the short light-on period and the defaulting to AC. Thanks again

Wonderful How-to video. Thank you. Can you advise what markings are on your EEPROM chip in the UT210E? When using the settings you have used (24_EEPROM, ATMEL, AT24C02) I get a message indicating the chip is empty. Rechecked connection & tried other Chip types but still returns the chip is empty. Mine has PC24C08C & 1L2TG5 and there does not seem to be a corresponding chip in the ESP2019 software nor on Google. Interestingly, when I used the Test option, the software identifies the chip type as 93_EEPROM.
@Raphael_Hofmann Жыл бұрын
On the EEPROM, I can find this information: P24C08C 2K2TN2 Or: T24C08A 20NB3 Did you try to file off some plastic on the clamp, so that it can reach deeper in and is not stopped by the metal housing next to the chip?
@Raphael_Hofmann Жыл бұрын
You can also try to swich the meter off and on again. It worked well in the 2A range for me. Just make sure, you saved the original EEPROM DUMP for a backup, befor you write your modified code to the EEPROM. You can always go back to the original state and start from scratch with your settings.

That might be a useful detail for people who have the UT210D. Thanks for this comment! As far as I know, there is no way to hard reset. And even if you do that, you loos all the calibration values from the factory. So it is best to save a copy of your EEPROM dump before you do any modifications.

Just got the exact same Programmer, and had a go at my UT210E Pro. (Newer version, including Frequency) The programmer clamp is a bit flaky, but I got it to connect properly with the EEprom. Swapped AC and DC, since I work mostly in automotive and battery devices. Set Backlight to Infinite (0) Set Aoto Off at 60 Minutes. Added AC mV as a second function on the NCV so it reads a voltage to more exactly search the conductor in a wall by going to its peak value. Wrote that to the EEprom, and it works as desired for me. :-) Very good video, and with your help I reporogrammed that meter perfectly to suit my needs.

@Raphael_Hofmann Жыл бұрын
The accuracy did not change, as far as I can tell. But the main benefit of the mods are the increased resulution. Therefore you can see small changes in voltage over time. I ran into a problem on some of the meters, that I modded: Some of them just get stuck and do not show OL (overload), when the current exceeds the range. If you reduce the range to 9000 count or even 8000 count in some cases, it works just fine. For a 8000 count meter you could set the parameter "Full Scale:" to 8000 and "Range Switch Upper Limit: " to 8200". Than it works just fine. It has to do with the calibration of the Multimeters.

@charly_a8654 Жыл бұрын
some considerations about this hack: you get more resolution, this is good. But you don't get more precision, this you have to consider when interpreting your measurement. In every range you get 199 to 1999 counts, this is a resolution from 0,5% to 0,05%. The best precison is 0.7%+5 digits in DC-V (see on data-sheet). All others are worse. This matches well. The hack increases the resolution from 999 to 9999 this means 0.1% to 0.01% this is far away from the over-all precison. And you can't calibrate it better, becaus the whole hardware is not better. There are errors in linearity, temperature behaviour, magnetic errors, and many more. The better choice for measuring dc-voltage would be a real 4-digit multimeter.

There's probably a reason these come up in AC mode - that form factor of meters probably gets used a lot by people doing field work on mains stuff, replacing traditional voltage testers. You want to make it really hard to accidentally put the meter in a setting where dangerous voltage mains is not displayed/gives odd readings mistaken for leakage....
@NicksStuff Жыл бұрын
Makes sense. But these offer a DC setting on the current clamp, which is fairly rare and won't interest electricians who work on mains voltage. So your point is valid but a lot of the buyers of these meters use them to work on DC almost exclusively.
