Details
The filter count is the number of readings that are acquired and stored in the filter stack for the
averaging calculation. When the filter count is larger, more filtering is done and the data is less noisy.
Example
dmm.measure.func = dmm.FUNC_DC_CURRENT
dmm.measure.filter.count = 10
dmm.measure.filter.type = dmm.FILTER_MOVING_AVG
dmm.measure.filter.enable = dmm.ON
Set the measurement function to
current.
Set the averaging filter type to moving
average, with a filter count of 10.
Enable the averaging filter.
