Appendix D. Calibration
Overview
The calibration of the unit is software dependent; there are no potentiometers to
adjust.
The calibration points are set to 10% and 90% of the rated outputs and calibration
data is automatically calculated from the measurement date you provide.
The setting and readback accuracy of the power supply should be checked annually,
and calibration done only if the unit is not operating within its specification.
The OTP and AC off protection mechanisms are operational during calibration. All
other protection mechanisms are disabled.
Entering Calibration Mode
Calibration mode is entered by using the "change calibration state" SCPI command.
Ensure you are in remote mode and have the appropriate remote source setting.
To access calibration mode via remote interface, use the command:
