New UNI-T UT210E PRO problem

Interesting.  In this case, if there is any remaining magnetism on the clamp, the recalibration does not remove it.  Only calibrates the current value to zero.  The question is whether the other measurements remain the same.  Maybe I'll try, I'm just scared of:

"ATTENTION! To do only if there is a backup copy of EEPROM!"

I have specifically highlighted this warning in bold text!
If you do not have a copy of your device's EEPROM, then there is a very high risk of damaging the contents of memory cells if unsuccessful actions are taken. This dump is unique to each instrument and is calibration using standards at the factory. Bear this in mind, I warned. ;) In addition, a backup copy of the EEPROM can greatly help in restoring the operation of the device if a failure occurs or the cells of the 24C02 (08) microcircuit are damaged. This situation can happen with any device in this category and has already happened to some owners of multimeters based on the DTM0660 processor and its analogues.

OK, thanks!
... But, how do one make a copy of the EEPROM then? And restore it, if need be?

I wonder what's the CHIPSET? It's the same as the "regular" UT210E? DM1106EN ??  If yes, you can hack it from 2,000 counts to 10,000 counts.

Maybe your "UT210E Pro" firmware could be useful to unlock the Frequency e more Capacitance range in the regular UT210E.

Please, could you check this out?
