This command sets the voltage range of the power source . Two voltage ranges are available: a
135 volt range and a 270 volt range. However, to allow this voltage to be present at the load,
the AC source allows voltage settings slightly higher than this. This allows for one or two volt
of cable loss. Consequently, the actual voltage range values will be slightly higher than 135
and 270. To determine the actual range values, use the query format of the RANGE
command. The returned values for high and low range (e.g. 136 and 272) should be used to
change range. In any case, the high voltage range value will be two times the low voltage
range value. Sending a parameter other than the actual range values will not be accepted.
Some P Series may use other voltage range values than shown here. It is recommended to
query the actural range values using the LIM:VOLT? query as part of your application program.
When the range is set to 136, the maximum rms. voltage that can be programmed is 136 volts.
The VRANGe command is coupled with the CURRent command.This means that the
maximum current limit that can be programmed at a given time depends on the voltage range
setting in which the unit is presently operating.
