Calibration Command Reference
3-7
:V2 (:CALibration:PROTected:DC:V2)
Purpose To program the +2V comprehensive calibration step.
Format :cal:prot:dc:v2 <Cal_voltage>
Parameter <Cal_voltage> = 0.95 to 2.05 [V]
Description :V2 programs the +2V DC comprehensive calibration step. The allowable range of the calibra-
tion voltage parameter is from 0.95 to 2.05V, but 2V is recommended for best results.
Example :CAL:PROT:DC:V2 2 Program 2V step.
:V20 (:CALibration:PROTected:DC:V20)
Purpose To program the +20V DC comprehensive calibration step.
Format :cal:prot:dc:v20 <Cal_voltage>
Parameter <Cal_voltage> = 9.5 to 20.5 [V]
Description :V2 programs the +20V DC comprehensive calibration step. The allowable range of the calibra-
tion voltage parameter is from 9.5 to 20.5V, but 20V is recommended for best results.
Example :CAL:PROT:DC:V20 20 Program 20V step.
:OHM1M (CALibration:PROTected:DC:OHM1M)
Purpose To program the 1MΩ comprehensive calibration step.
Format :cal:prot:dc:ohm1m <Cal_resistance>
Parameter <Cal_resistance> = 475E3 to 1.025E6 [Ω]
Description :OHM1M programs the 1MΩ comprehensive calibration step. The allowable range of the cali-
bration resistance parameter is from 475kΩ to 1.025MΩ. Use the 1MΩ value whenever possi-
ble, or the closest possible value.
Example :CAL:PROT:DC:OHM1M 1E6 Program 1MΩ cal step.
