Calibration Reference B-9
DC calibration commands
The :DC commands perform calibration of the DCV, DCI, and ohms functions. Table B-2
summarizes these calibration commands along with parameter limits.

DC calibration commands
: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.
