Average On/Off8.2.5
Name: MEDIAN
Description: Switches between „Averaging on“ and „Averaging off“. The median is generated from a preset
number of measurement values. Here the inputted measurement values (3 measurement values) are resorted
after each measurement. The average value is then outputted as the median. When the median is gener-
ated in the controller only 3 measurement values are taken into account, i.e. a 0 median is not possible. This
means that individual interference pulses can be suppressed. The measurement value curve is not smoothed
to a great extent.
Byte 9 = 0; Median off
Byte 9 = 1; Median on
Default setting:
Median off
