Calibration Command Reference
3-10
:HIGH
(:CALibration:PROTected:DC):HIGH
Purpose To program the +20V DC comprehensive calibration step.
Format :cal:prot:dc:high <cal_voltage>
Parameters <Cal_voltage> = 10 to 20 [V]
Description :HIGH programs the +20V DC comprehensive calibration step. The allowable range of the
calibration voltage parameter is from 10 to 20V, but 20V is recommended for best results.
Programming example 10 OUTPUT 716; “:CAL:PROT:DC:HIGH 20” ! Program 20V step.
:LOHM
(CALibration:PROTected:DC):LOHM
Purpose To program the 20k¾ comprehensive calibration step.
Format :cal:prot:dc:lohm <cal_resistance>
Parameters <Cal_resistance> = 9E3 to 20E3 [¾]
Description :LOHM programs the 20k¾ comprehensive calibration step. The allowable range of the
calibration resistance parameter is from 9k¾ to 20k¾ (9E3 to 20E3). Use the 20k¾ value
whenever possible, or the closest possible value (for example, 19k¾, which is the closest
value available on many calibrators).
Programming example 10 OUTPUT 716; “:CAL:PROT:DC:LOHM 19E3”! Program 19k¾.
:HOHM
(CALibration:PROTected:DC):HOHM
Purpose To program the 1M¾ comprehensive calibration step.
Format :cal:prot:dc:hohm <cal_resistance>
Parameters <Cal_resistance> = 800E3 to 2E6 [¾]
Description :LOHM programs the 1M¾ comprehensive calibration step. The resistance parameter can
be programmed for any value from 800k¾ (800E3) to 2M¾ (2E6). Use the 1M¾ value
whenever possible, or the closest possible value on your calibrator for best results.
Programming example 10 OUTPUT 716; “:CAL:PROT:DC:HOHM 1E6” ! Program 1M¾ step.
