:A2 (CALibration:PROTected:DC:A2)
Purpose To program the 2A comprehensive calibration step.
Format :cal:prot:dc:a2 <Cal_current>
Parameter <Cal_current> = 0.95 to 2.05 [A]
Description A2 programs the 2A comprehensive calibration step. The allowable range of the calibration cur-
rent parameter is from 0.95A to 2.05A. Use the 1A value whenever possible for best results.
Example :CAL:PROT:DC:A2 1 Program 2A step.
3.3.9 :LLEVel (:CALibration:PROTected:LLEVel)
