Notes:
– The statistics data must be deleted before each new measuring task

– In the case of rough, contaminated surfaces, averaging may improve
the measurement result.
– Statistics can be used to determine the average coating thickness on
extensive measurement areas; to do this, set at least 10-20 measuring
points distributed across the entire area.
