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 133). 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.
