5-3. Moving average filter
This filter takes the moving averages of sampled data and reduces fluctuation of indicated values.
The number of moving averages can be selected from OFF (zero, once) to 999 times. The more the
number of moving averages, the more stable the indicated values, but response will be slower.
Conversely, the less the number, the quicker the response, but indicated values will be more likely
to fluctuate. Set the most appropriate value in accordance with the kinds of measurements.
