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?

VOLTPROT? MAX and VOLTPROT? MIN return the maximum and minimum programmable overvoltage trip levels This query returns the currently selected range. The returned parameter for the Agilent E3633A is ‘‘P20V’’ HIGH or ‘‘P8V’’ LOW and the parameter for the Agilent E3634A is ‘‘P50V’’ HIGH or ‘‘P25V’’ LOW Triggering Commands Trigger Source ChoicesTo select the immediate trigger source, send the following command Triggering Commands DISPlay OFF ON System-Related CommandsChapter 4 Remote Interface Reference System-Related Commands DISPlay?SYSTemERRor? Chapter 4 Remote Interface Reference System-Related CommandsOUTPREL command +0, ‘‘No error’’This command resets the power supply to its power-on state as follows To recall a stored state, you must use the same memory location used Calibration Commands This command corrects the differential nonlinearity error of the internal DAC without an external meter. 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 Event Register?
