VOLTage:PROTection? {MINimum|MAXimum}
This query returns the overvoltage protection trip level presently programmed.
VOLT:PROT? MAX
and
VOLT:PROT? MIN
ret urn the ma ximum an d minimum
programm able overvoltage trip levels.
VOLTage:PROTection:STATe {0|1|OFF|ON}
This com mand enables or disabl es the overvoltage protection function. An
overvoltage condition can be cleared with the
VOLT:PROT:CLE
command
after the condition that caused the OVP trip is removed. At
*RST
, th i s v alu e i s
set to ‘‘ON’’.
VOLTage:PROTection:STATe?
This query returns the state of the overvoltage protection function. The
returned parameter is ‘‘0’’ (OFF) or ‘‘1’’ (ON).
VOLTage:PROTection:TRIPped?
This query returns a ‘‘1 ’’ if the overvolt age prot ection circuit is tripped and not
cleared or a ‘‘0’’ if not tripped.
VOLTage:PROTection:CLEar
This com mand cau ses the overvoltage pr otection circui t to be cleared. After
this command, the output voltage is restored to the state it was in before the
protection feature occurred an d the OVP trip level remains unchanged to the
value presently programmed. Before sending this comma nd, lower t he output
voltage below the trip OVP point, or raise the OVP trip level above the output
setting.
Note that the overvoltage condition caused by an external source must
be rem oved firs t before proc ee ding this c omm a nd.
VOLTage:RANGe {P8V|P20V||LOW|HIGH} (For E3633A model)
or {P25V|P50V|LOW|HIGH} (For E3634A model)
This command selects an output range to be programmed by the identifier. For
example, when 8V/20A * range is selected, the
maxim u m program mable
voltage and cu rrent are limi ted to 8.24 volts and 20.60 amps. W hen 20V/10A *
range is selected, the
m aximum programm able
voltage and current are
limited to 20.60 volts and 10.30 amps. See
page 70 for more detail s of the
programm ing ranges of the Agil ent E3634A model. ‘‘P20V’ ’* or ‘‘HIGH’’ is the
identifier for the 20V/10A* range and ‘‘P8V’’* or ‘‘LOW’’ is for the 8V/20A* range.
At
*RST
, the 8V/20A* or 25V/7A ** range is selected.
