Moving average function

This function calculates the mean value by performing moving average processing on the sampling pulse number obtained
per count cycle for the specified number of times of averaging operations. Use this function in situations such as when
variations occur in the sampling pulse number.
Operation
Setting 'CH1 Movement averaging processing selection' (Un\G132) to Moving average processing (1) causes average
processing to be performed on the sampling pulse number. Use 'CH1 Number of movement averaging processing' (Un\G133)
to set the number of times to perform averaging on the sampling pulse number.
When 'CH1 Movement averaging processing selection' (Un\G132) is set to Sampling processing (0), the sampling pulse
number is calculated without averaging processing.
■Example
This section describes an operation example when 'CH1 Number of movement averaging processing' (Un\G133) is set to 4.
Until the set count of sampling pulse numbers is calculated, averaging processing is performed with the current count.
