AN8008 US $19, 9999count, 1uV, 0.01uA, 0.01Ohm, 1pF resolution meter

btw, fun aside.
if you take the piss with the input voltage in current-mode you dont need to worry about the fuse because the Transorb suppressor will clamp-on and take the track off the switch.
i know this because i was given an 8002 for free after it happened to someone else!

Hi, I'm a new user and I would like to say a big thanks to everyone since the pages of this forum are a goldmine for electronics enthusiasts like me.
That aside, I bought a new aneng 8008 and did the hardware updates suggested by jackenhack which really improved the meter.
Then I went on to modify my eeprom. Basically the only thing I needed was temperature, so I went on and added that to the mV range.
However, I don't have the calibration data (eeprom addresses 0x0B to 0x0F) and my meter is overshooting temperature. I know how I can modify addresses 0x0B, 0x0C to make the meter read lower, but since there's also the ADC value at addresses 0x0D to 0x0F, I'd rather copy these from an ANENG 8002 or ANENG 8009. Problem is, I looked everywhere for the eeprom contents of these meters and found nothing!
Could anyone help please?

Is there something preventing me from applying more than 36V to the current input? :popcorn:

8002 (3 different ones)
FA 00 C0 CE 03
E6 00 00 BD 03
F0 00 48 CE 03
8008
FA 00 00 BE 03 < this is the default value in the datasheet.

Thank you so much stj, I will use these data to calibrate my meter and let you know how it went. Interesting thing though how you have three different versions of data for the same meter (hardware).
