Special Calibrations

Perform a "Special" Calibration
CHSE?
Triggers special calibration
ADC
Aligns the different resolutions available from the analog to digital converter, so that
there are no significant differences in readings when changing resolutions with a constant
input value.
FREQ
Calibrates the frequency counter against an external frequency standard, by correcting an
internal frequency 'gain' factor.
HV_LIN
ONLY used after the five linearity measurements have been taken using the command
HV_LIN? <parameter>, to calculate the DC high voltage linearity correction from these
measurements.
Response
(Nr1) The value returned identifies the success (0) or failure (1) of the calibration step.
Execution Errors
If special calibration is not enabled.
