Measured value averaging type:
0 - No averaging
1 - Moving average
(Number of values for moving average: 2, 4, 8, 16, 32,
64, 128, 256, 512 and 1024)
2 - Recursive average
(Number of values for recursive average: 2…32768)
3 - Median
(Number of values for median: 3, 5, 7 and 9)
Statistic depth:
0, 2, 4, 8, 16…16384; 0 = infinite
Error handling:
0 - Output of error value
1 - Hold last valid value for a number of measurement values
(Number of held values: 0….1024, 0 = infinite)
Video averaging:
0 - No averaging
1 - Recursive average of 2 video signals
2 - Recursive average of 4 video signals
3 - Recursive average of 8 video signals
4 - Moving average of 2 video signals
5 - Moving average of 4 video signals
6 - Moving average of 3 video signals
7 - Median of 3 video signals
Statistic signal: Measurement, for which the statistics is calculated (only in measurement
program multilayer)
