Used to switch laser beam on and off. Laser beam is ON when Q
beam is switched OFF. Last measured value remains. When reactivated, the response time is
prolonged according to the set mean value.

Explanation of averaging:
Moving averaging „smooths" the measuring result (output signal) and enables the „masking" of
individual imperfections (e.g. when measuring objects with rough surfaces).
The measured values are read continuously into a memory and the arithmetical mean is
formed. Functions no.14 and no.15 determine the number of measurements (10 or 100) to be
used for averaging.
With a scanning rate of 0.4 ms per measurement, the response time lies between 0.4 ms
(without averaging) and 40 ms.
