:OHM200 (CALibration:PROTected:DC:OHM200)
Purpose To program the 200Ω comprehensive calibration step.
Format :cal:prot:dc:ohm200 <Cal_resistance>
Parameter <Cal_resistance> = 95 to 205 [Ω]
Description :OHM200 programs the 200Ω comprehensive calibration step. The allowable range of the
calibration resistance parameteris from 95Ω to 205Ω. Use the 200Ω value whenever possible,
or the closest possible value (for example, 190Ω, which is the closet value available on many
calibrators).
Example :CAL:PROT:DC:OHM200 190 Program 200Ω step.
:OHM20 (CALibration:PROTected:DC:OHM20)
Purpose To program the 20Ω comprehensive calibration step.
Format :cal:prot:dc:ohm20 <Cal_resistance>
Parameter <Cal_resistance> = 9.5 to 20.5 [Ω]
Description :OHM20 programs the 20Ω comprehensive calibration step. The allowable range of the
calibration resistance parameter is from 9.5Ω to 20.5kΩ. Use the 20Ω value whenever possible,
or the closest possible value (for example, 19Ω, which is the closet value available on many
calibrators).
Example :CAL:PROT:DC:OHM20 19 Program 20Ω step.
:A200U (CALibration:PROTected:DC:A200U)
Purpose To program the 200µA comprehensive calibration step.
Format :cal:prot:dc:a200u <Cal_current>
Parameter <Cal_current> = 95E-6 to 205E-6 [A]
Description :A200U programs the 200µA comprehensive calibration step. The allowable range of the cali-
bration current parameter is from 95µA to 205µA. Use the 200µA value whenever possible for
best results.
Example :CAL:PROT:DC:A200U 200E-6 Program 200µA step.
