Keithley 2001 Calibration Manual

Calibration Command Reference
3-9
3.3.10 :DC
(CALibration:PROTected):DC
The :DC commands perform comprehensive (user) calibration. Table 3-3 summarizes these
comprehensive calibration commands.
:ZERO
(:CALibration:PROTected:DC):ZERO
Purpose To perform short-circuit comprehensive calibration.
Format :cal:prot:dc:zero
Parameters None
Description :ZERO performs the short-circuit calibration step in the comprehensive calibration proce-
dure. A low-thermal short (Model 8610) must be connected to the input jacks before send-
ing this command.
Programming example 10 OUTPUT 716; “CAL:PROT:DC:ZERO” ! Do short-circuit cal.
:LOW
(:CALibration:PROTected:DC):LOW
Purpose To program the +2V DC comprehensive calibration step.
Format :cal:prot:dc:low <cal_voltage>
Parameters <Cal_voltage> = 1.0 to 2.0 [V]
Description :LOW programs the +2V DC comprehensive calibration step. The allowable range of the
calibration voltage parameter is from 1.0 to 2.0V, but 2V is recommended for best results.
Programming example 10 OUTPUT 716; “:CAL:PROT:DC:LOW 2” ! Program 2V step.
