--- Quote from: thaistatos on November 17, 2018, 09:17:20 pm ---I run into problems flashing the chip.
I followed instructions from
got a programmer, test clip, reading of data was ok and was exactly the same the examples.
When trying to flash there was a message " chip main memory with the contents are in disagreement"
Software version used was 1.29 on Windows 10.
I tried different other older and newer software versions without success.
erasing and verifying even without test clip attached gives the same positive feedback.
I assume test clip should be ok, as reading was without problems.
There are rumors that 1,29 could not write, but other software versions did not help.
Any ideas?

edit:
Solution: checked the continuity between the pins at the flasher and the pins at the PCB with attached test clip. Turns out test clip is crap. I had to push it directly to the PCB, otherwise it either looses contact on pin 4 GND or pin 7 WP.
Does anyone has a link to better test clip available?

Well cool video!

I also have the UT210E and think it really is an awesome wee meter! It is as accurate as all my other meters which are much more high end. To the point of being uncanny! I couldn't believe it at 1st!
I keep trying to catch it out hoping it'll measure way off the mark, to try and justify to myself the extra £££'s I've(stupidly) spent on all the other meters. I haven't managed to yet and i'm sure it flips me "the bird" every time it hangs with them no probs ! :)


Just to put things in perspective the cheapest meter after the UT210E is 4 times as expensive, the worst is well over 10 times the price of the UT210E! Sure a couple have a odd feature the UT210E doesn't have but.... go figure! I would recommend the UT210E to anyone! It really is an awesome wee meter!

thaistatos:
anyone experienced problems with the autorange in resistance measure mode with 10000 count?
I flashed to 10000 count and tried to measure for example 10k.
Coming from short circuit to 10k it says OL, coming from open loop to 10k it seems ok. Same problem with 1k, 100k and most probably 1M, but as resistance is a little bit off (or UT210) it displays 998k, which seems to work.

JonnyM:
I hooked mine up to an arduino and made a backup of the eeprom
then I copied the 0x50 and 0x51calibration values to the JAY_i2cArduino210E.ino and ran the arduino program. Now my voltage and resistance is messed up. It reads 1.7 ohms with nothing connected.. Current ranges works fine. Is it possible to reflash my full backup.hex using just an arduino? :scared:

jayjr1105:
Did you make sure you don't have the older chip? It can't do 10000 count.  Before and after dumps would help us determine if anything is wrong.

actually it can do 10,000 count - just not in AC volts - the true-RMS function cant handle it above 7,000 counts.
