Commands
Measure range commands:
smuX.measure.autorangei = smuX.AUTORANGE_ON
smuX.measure.autorangei = smuX.AUTORANGE_OFF
smuX.measure.autorangev = smuX.AUTORANGE_ON
smuX.measure.autorangev = smuX.AUTORANGE_OFF
smuX.measure.lowrangei = lowrange
smuX.measure.lowrangev = lowrange
smuX.measure.rangei = rangeval
smuX.measure.rangev = rangeval
Source range commands:
smuX.source.autorangei = smuX.AUTORANGE_ON
smuX.source.autorangei = smuX.AUTORANGE_OFF
smuX.source.autorangev = smuX.AUTORANGE_ON
smuX.source.autorangev = smuX.AUTORANGE_OFF
smuX.source.limiti = level
smuX.source.limitv = level
smuX.source.lowrangei = lowrange
smuX.source.lowrangev = lowrange
smuX.source.rangei = rangeval
smuX.source.rangev = rangeval
* smuX = smua for the Model 2601/2611; smuX = smua (Channel A) or smub (Channel B) for the Model 2602/2612.
** See Table 6-1 for measure ranges.
*** See Table 6-1 for source ranges
Range programming example
The listing below shows a programming example for controlling both source and measure ranges.
The SourceMeter is set up as follows:
• Voltage source range: auto
• Current measure range: 10mA
• Measure low range: = 10μA
• Voltage source current limit: 10mA

smua.reset()
--Restore Series 2600 defaults.
smua.source.autorangev = smua.AUTORANGE_ON
--Set V source range to auto.
smua.measure.rangei = 1e-2
--Enable 10mA measure range.
smua.measure.lowrangei = 1e-5
--Set lowest range to 10μA.
smua.source.limiti = 1e-2
--Set limit level to 10mA.
