Details
This command selects the window size for the averaging filter.
The noise window allows a faster response time to large signal step changes. A reading that falls
outside the plus or minus noise window fills the filter stack immediately.
If the noise does not exceed the selected percentage of range, the reading is based on an average of
reading conversions — the normal averaging filter. If the noise does exceed the selected percentage,
the reading is a single reading conversion, and new averaging starts from this point.
Example
dmm.measure.func = dmm.FUNC_RESISTANCE
dmm.measure.filter.type = dmm.FILTER_MOVING_AVG
dmm.measure.filter.window = 0.25
dmm.measure.filter.enable = dmm.ON
