After the recap and display replacement, I decided to perform a DC calibration.
For safety, I made a backup of the 24LC16.
I was only missing a 100 kΩ reference resistor, so I used an old calibrator instead (after first measuring its actual resistance with a reference multimeter).
I decided not to perform current calibration because I don’t have a good reference current source.
Steps:
:CAL:PROT:CODE 'KI002010'
:CAL:PROT:INIT
:CAL:PROT:DC:STEP3 10 9 to 11
:CAL:PROT:DC:STEP4 -10 -9 to -11
:CAL:PROT:DC:STEP5 100 90 to 110
:CAL:PROT:DC:STEP6 10
:CAL:PROT:DC:STEP7 1E3
:CAL:PROT:DC:STEP8 10E3
:CAL:PROT:DC:STEP9 100E3
:CAL:PROT:DC:STEP10 1E6
:CAL:PROT:DATE <year>, <month>, <day>
:CAL:PROT:NDUE <year>, <month>, <day>
:CAL:PROT:SAVE
:CAL:PROT:LOCKThe result turned out pretty good:









P.S.
The device has already been shipped to its new owner.
