5.6 Output value filter

The LLB measuring system contains a filter for the measurement value, which can be activated and
offers different configurations. This filter is available in the following Measuring characteristics (see
5.4.1 "Measuring characteristics overview" 108):
Normal
-
Fast
-
Precise
-
Natural Surface
-
Timed
-
The output value filter is made of a moving average, spike suppression or as error suppression. These
filters are all configurable with the command "Set/Get measurement filter configuration (sNfi)"
(chapter 10.3.7 on page 144) to offer most possible flexibility for the adaption of the LLB device to
various applications.
The filter is inactive for the moving target characteristic.

The moving average filter averages a specified
number of
measurement values can be averaged. If a new
measurement value is present, this value will be
added to the filter values, while the last value will be
removed (see
measurement values divided by the size of the filter
is transferred to all outputs.
The spike suppression eliminates pairs of min max
values inside the filter values (Number of filter
values can be defined). Always the smallest and
largest values are removed from the average
calculation.
A maximum number of errors inside the filtered
values can be suppressed. If the number of errors
inside the filtered values is less as the specified
value, no error is shown at the output.
See 10.3.7 "Set/Get measurement filter
configuration (sNfi)" on page 144.
