B-12 Calibration Reference Model 2750 Multimeter/Switch System Service Manual
:STEP11
(CALibration:PROTected:DC:STEP11)
Purpose To program the 100mA comprehensive calibration step.
Format :cal:prot:dc:step11 <Cal_current>
Parameters <Cal_current> = 90E-3 to 110E-3 [A]
Description :STEP11 programs the 100mA comprehensive calibration step. The
allowable range of the calibration current parameter is from 90E-3 to
110E-3. Use the 100E-3 value whenever possible for best results.
Example :CAL:PROT:DC:STEP11 0.1 Program 100mA step.
:STEP12
(CALibration:PROTected:DC:STEP12)
Purpose To program the 1A comprehensive calibration step.
Format :cal:prot:dc:step12 <Cal_current>
Parameters <Cal_current> = 0.9 to 1.1 [A]
Description :STEP12 programs the 1A comprehensive calibration step. The allow-
able range of the calibration current parameter is from 0.9 to 1.1. Use a
value of 1 whenever possible for best results.
Example :CAL:PROT:DC:STEP12 1 Program 1A step.
