Operation
3–16 TM-XR9B-01XN
VRHI The power supply outputs a voltage value to an external voltmeter connected as
part of the calibration procedure and records a voltage readback value internally.
These values are at the high end of the programmed voltage range. Refer to the
output value as VRHI and record it to use as input with the VRDAT command. Set
CMODE ON before using this command. See also the calibration procedures in
Chapter 4.
VRLO The power supply outputs a voltage value to an external voltmeter connected as
part of the calibration procedure and records a voltage readback value internally.
These values are at the low end of the programmed voltage range. Refer to the
output value as VRLO and record it to use as input with the VRDAT command. Set
CMODE ON before using this command. See also the calibration procedures in
Chapter 4.
VSET <voltage>
or
VSET <-voltage>
Sets the power supply’s output voltage in volts (default) or in millivolts. This
programmed voltage is the actual output in CV (constant voltage) mode or the
voltage limit in CC (constant current) mode.
If you enter a negative voltage value, the power supply will assert a signal on Pin 4
of the user signal line. You can use the user signal to trip external relays to switch
the output polarity.
Range: 0 to model maximum output voltage (VMAX)
Initial value: 0 volts
VSET? Asks for the power supply’s present output voltage setting. Does not apply to
voltage settings which are being held. See HOLD command.
Response: VSET <voltage>
