User’s Manual SCPI Command Reference 18-77
The above command will select the 20V range for the V-Source.
As listed in the “Parameters,” you can also use the MINimum,
MAXimum and DEFault parameters to manually select the source
range. The UP parameter selects the next higher source range, while
DOWN selects the next lower source range.
Note that source range can be selected automatically by the instrument
(see next command).
AUTO <b>
:SOURce[1]:CURRent:RANGe:AUTO <b> Select auto range for I-Source
:SOURce[1]:VOLTage:RANGe:AUTO <b> Select auto range for V-Source
Parameters
<b> = 0 or OFF Disable auto range
1 or ON Enable auto range
Query
AUTO? Query state of auto range
Description This command is used to enable or disable auto range for the specified
source. When enabled, the instrument will automatically select the most
sensitive range for the specified source level. When disabled, the instru-
ment will use the range that the instrument is currently on.
Auto range will be disabled if a fixed range is selected (see previous
command).
Both *RST and :SYSTem:PREset enables source auto range. When the
SourceMeter goes into the local state, source auto range disables.
