Details
This command manually selects the measurement range for the specified source.
If you select a specific source range, the range must be large enough to source the value. If not, an
overrange condition can occur.
If an overrange condition occurs, an event is displayed and the change to the setting is ignored.
The fixed current source ranges are 10 nA, 100 nA, 1 µA, 10 µA, 100 µA, 1 mA, 10 mA, 100 mA,
and 1 A.
The fixed voltage source ranges are 200 mV, 2 V, 20 V, 200 V, and 1000 V.
When you read this value, the instrument returns the positive full-scale value that the instrument is
presently using.
This command is intended to eliminate the time required by the automatic range selection.
To select the range, you can specify the approximate source value that you will use. The instrument
selects the lowest range that can accommodate that level. For example, if you expect to source levels
around 50 mV, send 0.05 (or 50e-3) to select the 200 mV range.
If automatic range selection is set to on, when you select a specific range, automatic is set to off. To
set the range to automatic selection, use the source autorange command.
