3.6 Output value filter

The DLS-C(H)/FLS-C(H) 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 3.4 Measuring characteristics) on the DLS-C(H) and the FLS-C(H):
- Normal
- Fast
- Precise
- Natural Surface
- Timed
The output value filter is made of a moving average, a spike suppression as well as an error suppression filter. These filters are all
configurable to offer most possible flexibility for the adaption of the DLS-C(H)/FLS-C(H) device to various applications.
This filter is inactive for the moving target characteristic.

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

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

The moving average filter averages a specified number of measurements.
Maximum 32 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. The sum of all measurement values divided by the
size of the filter is transferred to all outputs.
