Pre-scale Function

This function converts the pulse number by multiplying the input pulse number by an arbitrary setting value.
Sampling pulse number calculation
The following arithmetic expression is used to convert the input pulse value per count cycle into a unit pulse number. The
converted value is stored in 'CH1 Sampling pulse number' (Un\G0) as the sampling pulse number.
