* See Available ranges
Range programming example
The programming example below illustrates how to control both source and measure ranges. The
Model 2651A is set up as follows:
•
Voltage source range: Auto
•
Current measure range: 10 mA
•
Voltage source current limit: 10 mA
-- Restore Model 2651A defaults.
smua.reset()
-- Set V source range to auto.
smua.source.autorangev = smua.AUTORANGE_ON
-- Select 10 mA measure range.
smua.measure.rangei = 1e-2
-- Set limit level to 10 mA.
smua.source.limiti = 1e-2
