Release 1.0 (97/10)
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 Section
4.
VSET <volt>
Parameter:
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 the J7-4
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 by the HOLD command. See HOLD command.
Response:
VSET <voltage>
