Mask function
The
Mask
function can be used to define one or more areas in which the device does
not make measurements. A typical application is the blanking of a transparent protec‐
tive screen located between the measuring object and device.

Setting the measurement value filter
The measurement value filters optimize the signal diagram in order to simplify the eval‐
uation by the control system (e.g., for regulation tasks). You can select from the follow‐
ing filters:
•
Average filter
•
Median filter
By default, the average filter is set to a filter depth of 256 measured values and the
median filter to a filter depth of 31 measured values.
Average filter
The average 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 average 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.
