[SOURce:]VOLT:RANGe[:LEVel]
This command sets the voltage range of the power source . Two voltage ranges are
available: a 150 volt range and a 300 volt range. However, 2001RP units with optional
voltage ranges are available as well. In this case, the actual voltage range values will be
different. To determine the actual range values, use the query format of the RANGE
command. The returned values for high and low range (eg. 150 and 300) should be used to
change range. In most cases, 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.
For 2001RP-AV models configured for single voltage range, only one range is available. In
this case, the VOLT:RANG commend will return the value for the only available range.
Attempting to select any other voltage range will result in a “–100, Command Error”. The
presence of a single voltage range unit may be determined using the Limit subsystem, see
section 10.6.
Some RP Series may use other voltage range values than shown here. It is recommended
to query the actual range values using the LIM:VOLT? query as part of your application
program. See section 10.6.
When the range is set to 150, the maximum rms voltage that can be programmed is 150
volts.
The VOLT:RANG 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.
