Calibration Subsystem

The commands in this subsystem allow you to do the following:

∙Control automatic calibration of the measurement subsystem.

∙Enable and disable the calibration mode.

∙Change the calibration password.

∙Calibrate the overvoltage protection (OVP) circuit.

∙Calibrate the current and voltage output levels, and store new calibration constants in nonvolatile memory.

CAL:AUTO

This command controls the autocalibration function and is used to substantially improve the accuracy of the MEAS:CURR? and MEAS:VOLT? data readback queries. It does this by compensating for temperature drift in the readback circuitry.
