Mean filter
The mean filter carries out a moving averaging of the measured values. This filter is
suitable for smoothing a noisy signal diagram in order to ensure better repeatability.
Filter depth: 1 / 2 / 4 / 8 / 16 / 32 / 64 / 128 / 256 (default value) / 512 / 1024 /
2048 / 4096 / 8192 / 16384 / 32768 / 65536 (unit: measuring point)
The mean filter can be deactivated by selecting filter depth 1.
Median filter
The moving median filter sorts the measured values according to their size and selects
the middle value from a sequence. This filter is suitable for excluding individual outliers
from the calculation of an average value.
Filter depth: Off / 7 / 15 / 31 (default value)
Both types of filter affect the response time of the device.
