Current offset calibration commands
Set the current offset calibration step by sending the following command:
:CAL:PROT:IOFF:STEP <step number>
This sets the step of the current offset calibration procedure. Steps are numbered from 1 to 5, and
correspond to the following instrument ranges:
1. All current ranges except 20 pA and 200 pA
2. 20 pA and 200 pA current ranges
3. 2 nC and 20 nC charge ranges
4. 200 nC and 2 mC charge ranges
5. 2 V, 20 V, and 200 V voltage ranges
For current offset calibration steps 1 and 2 only, the commands in the following table must be
executed after setting the current offset calibration step.
