Calibration command reference
Voltage offset calibration commands
Set the step for the voltage offset calibration with this command:
:CAL:PROT:VOFF:STEP <step number>
The steps are numbered from 1 through 6, and correspond to the following instrument ranges:
1. 20 pA and 200 pA current ranges
2. 2 nA, 20 nA and 200 nA current ranges
3. 2 mA, 20 mA, and 200 mA current ranges
4. 2 mA and 20 mA current ranges
5. 2 V, 20 V, and 200 V voltage ranges
6. 2 nC, 20 nC, 200 nC, and 2 mC charge ranges
Note that for each voltage offset calibration step, the following commands need to be executed after
setting the voltage offset calibration step:
:CAL:PROT:VOFF1
Start the first measurement for the voltage offset calibration
:CAL:PROT:VOFF2 <preamp out voltage reading>
Calibrate the first voltage offset point
:CAL:PROT:VOFF3
Start the second measurement for the voltage offset calibration
:CAL:PROT:VOFF4 <preamp out voltage reading>
Calibrate the second voltage offset point
