Details
When relative measurements are enabled, all subsequent measured readings are offset by the
relative offset value. You can enter a relative offset value or have the instrument acquire a relative
offset value.
Each returned measured relative reading is the result of the following calculation:
Displayed reading = Actual measured reading - Relative offset value
Example
dmm.measure.func = dmm.FUNC_AC_CURRENT
dmm.measure.rel.acquire()
dmm.measure.rel.enable = dmm.ON
Enables the relative measurements for AC
current and uses the acquire command to
set the relative level attribute.
