CURR? MAX and CURR? MIN return the highest and lowest programmable current levels for the selected range This command sets the current level at which the overcurrent protection OCP circuit will trip. If the peak output current exceeds the OCP level, then the output current is programmed to zero. The Questionable Status register ‘‘OC’’ bit is set see page 103. An overcurrent condition can be cleared with the CURRPROTCLE command after the condition that caused the OCP trip is removed The following program segments show how to use the VOLT UP or VOLTageSTEP numeric valueDEFault Output Setting and Operation CommandsVOLTageSTEP?

You must send this command before calibrating the voltage. It takes about 30 seconds to execute the command This command can only be used after calibration is unsecured and the output state is ON. It sets the power supply to a calibration point that is entered with CALVOLT command. During calibration, three points must be entered and the low-end point MIN must be selected and entered first RS-232 Interface Commands What is an Enable Register?
