To set a filter, see "Settings menu" on page 24.
Example
The following section outlines the behavior of the filter for measuring voltage in the version
AV5 with:
• Filter s = 2
• Filter co = 2 or 10
On the version AV5 the full scale is 400 V, therefore with Filter s = 2 the intervention range
is +/- 8 V (2% of 400 V). It should also be noted that the greater the value of Filter co, the
greater stability is obtained in measurements.
