Well I'd still say no you didn't. Why would there be a memory device that is 100% zeroes? Either that or the chip is faulty but you've not mentioned any faults.

I interpreted "read it correctly" as after removing the memory chip from the meter elman got a non-zeros reading.

Ah yes you may be right.

elman:
I'm sorry for creating confusion.
I removed the chip from the mother board and read it correctly (not 00 everywhere) , and I swapped the AC and DC functions.
I saw in a video and later tested that the memory chip cannot be read correctly if the rotary switch is in the OFF position, it must be in the 2A, 20A position... Now I can read the chip right on the board.
Now I want to correct the reading error on the ampere scale and on the 100A scale to increase the read value to 1000A.
Thank you for your interest.

New opamp in my UT210E, GS8334.
