Programmable DC Power Supply 62000L Series User's Manual
This command is used to program the pending triggered current level, which is a stored value
that is transferred to the output terminals when a trigger occurs. Subsequent CURRent
commands won't affect any pending triggered levels.
CURRent:TRIGgered? [MINimum|MAXimum]
This query command is used to query the triggered current level presently programmed.
When commanding CURR:TRIG? MAX and CURR:TRIG? MIN, the power supply returns the
highest and lowest programmable triggered current levels.
CURRent:PROTection {<current>|MINimum|MAXimum}
This command is used to set the current level where the overcurrent protection (OCP) circuit
will trip. If the output current is greater than the OCP level, the output current will be
programmed to zero. Then the Questionable Status register "OCP" bit will be set as well. This
condition can be cleared by commanding CURR:PROT:CLE after the condition caused the
OCP trip is removed.
CURRent:PROTection? {MINimum|MAXimum}
This query command is used to query the overcurrent protection trip level presently
programmed. When commanding CURR:PROT? MAX and CURR:PROT? MIN, the power
supply returns the maximum and minimum programmable overcurrent trip levels.
CURRent:PROTection:STATe {0|1|OFF|ON}
This command is used to enable or disable the overcurrent protection function.
CURRent:PROTection:STATe?
This query command is used to return the state of the overcurrent protection function. If the
OCP is enabled, 1 is returned. Otherwise 0 is returned.
CURRent:PROTecton:TRIPped?
This query command is used to query if a OCP tripped event occurred. If there is no OCP
tripped event occurred, 0 is returned. Otherwise 1 is returned. To clear OCP tripped event,
use the CURRent:PROTection:CLEar command.
CURRent:PROTection:CLEar
This command is used to clear the overcurrent protection tripped event. After commanding,
the output current is restored to the state in which it was before the current protection tripped
and the OCP trip level keeps unchanged to the value presently programmed. Before clearing
the tripped event, keep the output current lower than the trip OCP point, or adjust the OCP trip
level to be greater than the output setting.
MEASure:CURRent?
This command is used to query the current output value measured by the power supply. The
reading value is returned in the scientific format.
VOLTage {<voltage>|MINimum|MAXimum|UP|DOWN}
This command is used to set the CV limit level of the power supply. If the output is turn ON,
this commands change the output of the power supply to the newly programmed CV limit
level.
The MINimum or MAXimum can be substituted for a specific value used on current. The
predetermined UP or DOWN parameter can be used to increase or decrease one step of the
CV limit level. The command VOLTage:STEP describe below is used to set the amount of
increment and decrement step.
