ACAL subsystem
Automatic calibration removes measurement errors that are caused by the performance drift on the
components used in the source-measure unit (SMU) digitizer as a result of temperature and time.
If you are using the digitize functions on the Model 2461, it is important to run the automatic
calibration at least once a week.
