Keithley 2000 Calibration Manual

:STEP1
(:CALibration:PROTected:DC:STEP1)
Purpose To perform front terminal short-circuit calibration.
Format
:cal:prot:dc:step1
Parameter None
Description :STEP1 performs the short-circuit calibration step in the comprehensive cal-
ibration procedure. Connect a low-thermal short (Model 8610) to the front
panel input jacks before sending this command.
Example :CAL:PROT:DC:STEP1 Perform short-circuit calibration.
:STEP2 (:CALibration:PROTected:DC:STEP2)
Purpose To perform front terminal open-circuit calibration.
Format :cal:prot:dc:step2
Parameter None
Description :STEP2 performs the open-circuit calibration step in the comprehensive cal-
ibration procedure. Disconnect all cables and accessories from the input
jacks before sending this command.
Example :CAL:PROT:DC:STEP2 Perform open circuit calibration.
:STEP3 (:CALibration:PROTected:DC:STEP3)
Purpose To program the +10V comprehensive calibration step.
Format :cal:prot:dc:step3 <Cal_voltage>
Parameter <Cal_voltage> = 9 to 11 [V]
Description :STEP3 programs the +10V DC comprehensive calibration step. The allow-
able range of the calibration voltage parameter is from 9 to 11, but 10 is rec-
ommended for best results.
Example :CAL:PROT:DC:STEP3 10 Program 10V step.
Calibration Command Reference 3-11
