Averaging
7.4.8.1
General
The averaging is recommended for static measurements or slowly changing values.
Averaging
Inactive
Measurements are not averaged.
Moving N values
2 / 4 / 8 ... 128
Value Indication of averaging mode. The averaging
number N indicates the number of consecu-
tive measurement values to be averaged in
the sensor.
Recursive N values
2 ... 32768
Value
Median N values
3 / 5 / 7 / 9
Value
The averaging of measurement values is effected after the calculation of the displacement values prior to the
output via the interfaces.
The purpose of averaging is to:
- Improve the resolution
- Eliminate signal spikes or
- „Smooth out“ the signal.
Averaging has no effect on linearity.
In completion of the measuring cycle the internal average is calculated again.
i
The preset average value and the number of averaging are to save in the sensor, so that they remain
after switching off.
Averaging does not affect the measuring rate or data rates in digital measurement value output. The avera-
ging numbers can also be used if programmed via the digital interfaces. The sensor optoNCDT 1420 is sup-
plied ex factory with the default setting „Median 9“, that is, averaging with Median and 9 measurements.
Depending on the average type and the averaging number there is a different settling time, see Chap.
