The setting:
• Enable: smu.ON
• Disable:
smu.OFF
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:
Displayed reading = Actual measured reading - Relative offset value
Example
smu.digitize.func = smu.FUNC_DIGITIZE_CURRENT
smu.digitize.rel.acquire()
smu.digitize.rel.enable = smu.ON
Enables the relative measurements for
digitize current after using the acquire
command to set the relative level attribute.
