Model 2461 Interactive SourceMeter® Instrument Reference Manual

smu.digitize.rel.enable

This attribute enables or disables the application of a relative offset value to the measurement.
Type TSP-Link accessible
Attribute (RW) Yes
Usage
state = smu.digitize.rel.enable
smu.digitize.rel.enable = state
state
Details
When relative measurements are enabled, all subsequent digitized readings are offset by the relative
offset value that was calculated when you acquired the relative offset value.
Each returned measured relative reading is the result of the following calculation:
Example
smu.digitize.func = smu.FUNC_DIGITIZE_CURRENT
smu.digitize.rel.acquire()
smu.digitize.rel.enable = smu.ON
