Averaging
7.5.2.1
General
Averaging is recommended for static measurements or slowly changing measured values.
Averaging
Inactive
Measurement values 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
Measurement averaging is performed after the distance values have been calculated, and before they are
issued through the relevant interfaces.
Averaging
- improves the resolution,
- allows masking individual interference points, and
- ‘smoothes’ the reading.
Linearity is not affected by averaging.
The average values are continuously recalculated with each measurement. The desired averaging depth
is only achieved after the number of recorded measurement values corresponds at least to the averaging
depth.
i
The defined type of average value and the averaging number must be stored in the sensor to ensure
they are hold after it is switched off.
Grey shaded
fields require a
selection.

Dark-bordered
fields require
you to specifie
a value.
