Hello,
This is my first post on the blog (YAY!).
Unfortunately, my Aneng AN8009 has sort of miscalibrated somehow, it was showing values off the usual case and so upon reading few threads(including this one) I came to realize that the meter can be re-calibrated by jumping the J2 pins. Which I did and fiddled around the values. But me being stupid, didn't think of getting an accurate calibration tool( don't have access to one anyway) and made the problem worse. No the meter is pretty much useless as it gives some gibberish value (like 830mV for a 3.86V supply). Even the NCV function doesn't seem to work anymore.
So, basically, I was wondering whether I could flash the EEPROM with the stock calibration value dump? If so, where can I find the dump? I looked everywhere and I couldn't find it. I did look at Kerry D. Wongs blog on extracting the EEPROM dump and I have the necessary stuff to do it as well (Arduino and wires
)but there is no EEPROM dump for the AN8009 model. Will the AN8008 work with this?
I just need this working again ASAP. Any help is appreciated
Thanks & Regards
