UNI-T UT210E 10000 counts Clampmeter UPGRADE for BEGINNERS, Part 1

Beginner friendly tutorial: How to modify the UNI-T UT210E Multimeter.
If you follow the steps in the video, you can modify your own Clampmeter, which will become way more individual and useful. Especially considering the low price.

That is what you need:
UNI-T UT210E

EZP2019+

Optional, you can get a demagnetizer to reduce your DC-offset:

Benefits:
(1) Your meter can start up in DC-Mode, instead of AC-Mode for Voltage and Current
(2) Your meter will have a higher resolution - up to 10000 counts
(3) Your meter will start up in continuity measurement instead of resistance
(4) You can freely select your count range, measurement range, parameters for the meter to range up and down and in which order you want to select the modes.

The UT210E is also branded by Electronic companies.
Similar Meters with different functionality out of the box are those two:
- Voltcraft VC-337 (4000 counts up to 40A only)
- Extech MA63 (6000 counts up to 60A ony)

I just did the MOD and this multimeter is working now like was supposed to work from the factory. Thank you for the hard work done to build the calculator and for this great video.

[mcdemos]

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

[kevinrtres]

Amazing! i used to do these kind of things with CPUs in the 1980's!! So much more accessible and affordable to hobbyists these days.

[Neovo.Geesink]

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.

[MrRicciwalker]

thank you for this, I have more than 6 meters and the biggest issue is the default AC mode, now I can change. Just need a talking version....only one available in the US and they will not ship....thank you again and the originator for your efforts.

[MistrUnivrs]

Perfect display and splendid explanations. You helped me a lot with your video!

[upper_deck]

Perfekt! - Mit Deiner Anleitung kann eigentlich nichts schief gehen.

[tomblanar]

Excellent video Raphael! I just purchased the UT210D model that measures temperature and frequency too. Do you know if this type of hack has been worked out for that model? Thanks again for the effort to put this information out.

[radu_mol]

waw great hack, i own the ut210d and after entering to calibration mode by pressing select button and hold button doesnt work well, do you know if there is any way to hard reset or something? thank you

[caserio]

came from andy, ,,, grate vide let me see if i can do this to my multimeter grate video keep it up

[KeritechElectronics]

Look at the write protect line (WP) on the EEPROM in UT210D. If it's pulled down to GND, you can't write to the chip. Chances are you'll just have to desolder the part and program it out of board.

[bipedalprimate]

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.

[dtvking]

Many thanks, great work. Passed on from Andy with his Spat 🤣

[adon]

Thanks for the video. Does this work for other UNI-T meters? I have the UT216C model.

[charly_a]

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.

[Raphael_Hofmann]

I found a way to increase the measurement range from 100A to 1000A. I will also upload a video on how to do that soon:

[Chinhnguyen]

So can this be done for cheap Chinese DMM? like aneng and zotek with 2000 6000 count?

[jensschroder]

The voltage range should be at least 6 volts. Because 5 volt voltages are very common.
The UT210 is very popular because there are well-documented hacks are available.
It is not necessary to take out the batteries.

[simonspeaker]

NVC DIY FIX: use Bounce sheet (the sheet you put in your drying machine) and rub it on the meter and the test lead and the housing... it will prevent the meter from getting statics and beep for no reasons...

[universeisundernoobligatio]

Any idea with the modes what the meter accuracy and stability are now?
