I've messed up with my U1252B completely when I try to fix the resistor read a dozen of Mega when probe was opened. And I want to try copy the calibration data from another U1252, but I don't know which IC is, any hints about that ?
Is it this one? s93c86, it's an eeprom, the cap block the clutch readout without soldering, so i want to confirm before any soldering.
It's a s93c86 8KB eeprom, and can read out without anything breaking by a clutch and CH341 programmer, if you've never dumped it, you should before do any calibration...
U1252B and U1253B will do, it's almost the same version but U1253B has a nice OLED screen.
