Moving Average
The moving average is used to suppress the effects of noise that is riding on the signal.
The input signal of the measurement channel is set to the averaged value of the m most
current data points (the number of moving-averaged data points) acquired using the scan
interval. The number of moving-averaged data points (m) can be set in the range 2 to 16.
The figure below shows an example indicating the operation of the buffer for the moving
average computation when the number of moving averaged data points is set to “5.”
The moving average can be set on each channel. The moving average is initially turned
OFF.
