VOLTage:PROTection? {MINimum|MAXimum}
This query returns the overvoltage protection trip level presently programmed.
VOLT:PROT? MAX
and
VOLT:PROT? MIN
return the maximum and minimum
programmable overvoltage trip levels.
VOLTage:PROTection:STATe {0|1|OFF|ON}
This command enables or disables 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
, this value is
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 overvoltage protection circuit is tripped and not
cleared or a ‘‘0’’ if not tripped.
VOLTage:PROTection:CLEar
This command causes the overvoltage protection circuit to be cleared. After
this command, the output voltage is restored to the state it was in before the
protection feature occurred and the OVP trip level remains unchanged to the
value presently programmed. Before sending this command, lower the output
voltage below the trip OVP point, or raise the OVP trip level above the output
setting.
VOLTage:RANGe {P15V|P30V||LOW|HIGH}
This command selects an output range to be programmed by the identifier.
When 15V/7A range is selected, the maximum programmable voltage and
current are limited to 15.45 volts and 7.21 amps. When 30V/4A range is selected,
the maximum programmable voltage and current are limited to 30.09 volts
and 4.12 amps. ‘‘P30V’’ or ‘‘HIGH’’ is the identifier for the 30V/4A range and
‘‘P15V’’ or ‘‘LOW’’ is for the 15V/7A range. At
*RST
, the 15V/7A range is selected.
VOLTage:RANGe?
This query returns the currently selected range. The returned parameter is
‘‘P30V’’ (HIGH) or ‘‘P15V’’ (LOW).
