Output Setting and Operation Commands
CURRent:PROTection {<current>|MINimum|MAXimum}
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 91).
An overcurrent condition can be cleared with the CURR:PROT:CLE command after
the condition that caused the OCP trip is removed.
CURRent:PROTection? {MINimum|MAXimum}
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 {0|1|OFF|ON}
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.
