will make calculations which will stabilise the fluctuations of the measurement results. The meter dis-
plays a filtered value of measurements for a specified time period. The filter is selected by pressing the

the second press from the last 30 s, then for 60 s and finally the filter is turned off "- -". The filter setting
is circulating. The filter setting is erased automatically after the meter has been turned off or when the
measurement function is changed using the rotary selector.
The ability to set the filter depends on the set t measurement time, for example when t=20 s it is
only possible to set the filter for 10 s.
