Re-Installing Calibration Data - Ametek Amrel PLA Series Operation Manual

RE-INSTALLING CALIBRATION DATA

In case, the calibration data becomes corrupted by abnormal conditions, the Electronic Load has a built in capability for
re-installing the last calibration data without having to recalibrate the load.
1. First you need to read the slope and offset values from the electronic load when you receive the unit, or you can
call AMETEK Programmable Power Inc to get the calibration information for the electronic load (need serial
number)
Get calibration data procedure:
Get slope value:
Run command: "SYST : SL OPE? <mode>" to get calibration slope values where "mode" is from 0 to 39. So,
there should be 40 values for slope data.
Get offset value:
Run command: "SYST:OFFS? <mode>" to get calib ration offset values where "mode" is from 0 to 39. So,
there should be 40 values for offset data.
2. Once you obtain all the calibration information, you can resave this calibration information to the electronic load.
Resave calibration slope date to electronic load.
Run command: "SYST : SL OPE <mode> <value>" where "mode" is from 0 to 39, and the value is the
corresponding slope value obtained from 1.
Resave calibration offset date to electronic load.
Run command: "SYST: OFFS <mode> <value>" where "mode" is from 0 to 39, and the value is the
corresponding offset value obtained from 1.
After re-saving the calibration information for electronic load, you need test the CV and CC mode, and check if the reading back
values are within spec.
