Output Setting and Operation Commands

CURRent:PROTection {<current>MINimumMAXimum}

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 CURR:PROT:CLE command after the condition that caused the OCP trip is removed.

CURRent:PROTection? {MINimumMAXimum}

This query returns the overcurrent protection trip level presently programmed. CURR:PROT? MAX and CURR:PROT? MIN return the maximum and minimum programmable overcurrent trip levels.

CURRent:PROTection:STATe {01OFFON}

This command enables or disables the overcurrent protection function of the power supply. An overcurrent condition can be cleared with the CURR:PROT:CLE command after the condition that caused the OCP trip is removed. At *RST, this value is set to ‘‘ON’’.

CURRent:PROTection:STATe?

This query returns the state of the overcurrent protection function. The returned parameter is ‘‘0’’ (OFF) or ‘‘1’’ (ON).

CURRent:PROTection:TRIPped?

This query returns a ‘‘1’’ if the overcurrent protection circuit is tripped and not cleared or a ‘‘0’’ if not tripped.

CURRent:PROTection:CLEar

This command causes the overcurrent protection circuit to be cleared. After this command, the output current is restored to the state it was in before the current protection tripped and the OCP trip level remains unchanged to the value presently programmed. Before sending this command, lower the output current below the trip OCP point, or raise the OCP trip level above the output setting. Note that the overcurrent condition caused by an external source must be removed first before proceeding this command.
