3.12. Self Calibration

Head Self Calibration

For maximum accuracy, the M81-SSM has the ability to calibrate all of the circuitry to an internal precision standard. The internal standard must be factory calibrated annually.

For full specified accuracy, a self calibration must be performed within 24 h of use.

To initiate a self-calibration sequence, navigate to the calibration page. Here, you can also view information about the last self and factory calibrations.

A self cal can also be initiated from the SCPI interface using CALibration:SCALibration:RUN. The status of the self calibration is avaiable with the query CALibration:SCALibration:STATus?.

Module Self Calibration

Some modules support a self-calibration sequence for maximum accuracy. For specified accuracy, a self calibration must be performed within 24 h of use.

To initiate a self-calibration sequence, navigate to the module’s page and open the module information section. Here, you can also view the date of the most recent self-calibration of this module.

A self cal can also be initiated from the SCPI interface using SENSe#:SCALibration:RUN, or SOURce#:SCALibration:RUN.
