Number of Averaging Measurements
Take the following procedure to determine the number of times to average measured
values.
Setting Range
Select the number of averaging measurements from the following.
1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, 2048, and 4096
If you want to average the fluctuation of measured values and obtain stable results,
select a comparatively large number. For high-speed measurement, the number se-
lected should be comparatively small.
■ Averaging Time and Refresh Cycle
The LS-7000 Series averages measured values in a moving averaging method, thus
making it possible to output the measured values within a short time.
The following table lists the averaging time, the number of moving averaging data items,
and the refresh cycle of a target according to the number of averaging measurements.
