Keithley 2750 Service Manual

B-10 Calibration Reference Model 2750 Multimeter/Switch System Service Manual
:STEP5
(:CALibration:PROTected:DC:STEP5)
Purpose To program the 100V DC comprehensive calibration step.
Format :cal:prot:dc:step5 <Cal_voltage>
Parameters <Cal_voltage> = 90 to 110 [V]
Description :STEP5 programs the 100V DC comprehensive calibration step. The
allowable 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 100 4-wire comprehensive calibration step.
Format :cal:prot:dc:step6 <Cal_resistance>
Parameters <Cal_resistance> = 90 to 110 []
Description :STEP6 programs the 100 4-wire resistance comprehensive calibra-
tion step. The allowable range of the calibration resistance parameter is
from 90 to 110 but 100 is recommended for best results.
Example :CAL:PROT:DC:STEP6 100 Program 100 step.
:STEP7
(:CALibration:PROTected:DC:STEP7)
Purpose To program the 10k 4-wire comprehensive calibration step.
Format :cal:prot:dc:step7 <Cal_resistance>
Parameters <Cal_resistance> = 9E3 to 11E3 []
Description :STEP7 programs the 10k 4-wire resistance comprehensive calibra-
tion step. The allowable range of the calibration resistance parameter is
from 9E3 to 11E3, but 10E3 is recommended for best results.
Example :CAL:PROT:DC:STEP7 10E3 Program 10k step.
