Keithley 2000 Calibration Manual

:STEP4 (:CALibration:PROTected:DC:STEP4)
Purpose To program the -10V DC comprehensive calibration step.
Format :cal:prot:dc:step4 <Cal_voltage>
Parameter <Cal_voltage> = -9 to -11 [V]
Description :STEP4 programs the -10V DC comprehensive calibration step. The allow-
able range of the calibration voltage parameter is from -9 to -11, but -10 is
recommended for best results.
Example :CAL:PROT:DC:STEP4 -10 Program -10V step.
:STEP5 (:CALibration:PROTected:DC:STEP5)
Purpose To program the 100V DC comprehensive calibration step.
Format :cal:prot:dc:step5 <Cal_voltage>
Parameter <Cal_voltage> = 90 to 110 [V]
Description :STEP5 programs the 100V DC comprehensive calibration step. The allow-
able range of the calibration voltage parameter is from 90 to 110, but 100 is
recommended for best results.
Example :CAL:PROT:DC:STEP5 100 Program 100V step.
:STEP6 (:CALibration:PROTected:DC:STEP6)
Purpose To program the 1kΩ 4-wire comprehensive calibration step.
Format :cal:prot:dc:step6 <Cal_resistance>
Parameter <Cal_resistance> = 900 to 1.1E3 [Ω]
Description :STEP6 programs the 1kΩ 4-wire resistance comprehensive calibration step.
The allowable range of the calibration resistance parameter is from 900 to
1.1E3 but 1E3 is recommended for best results.
Example :CAL:PROT:DC:STEP6 1E3 Program 1kΩ step.
