Explanation of averaging:
Moving averaging „smooths" the measuring result (output signal) and enables the „mas-
king" 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.
Response times
0.4 ms = measured value (no average) (function 13)
4 ms = averaging with 10 measured values (function 14)
40 ms = averaging with 100 measured values (function 15)
Switch with
ON, if active
2
OFF, if inactive
SET
The last (max.) 10 measured values are used to form the average. For an explanation on
