Precautions
When using the pre-scale function, set 'CH1 Pre-scale setting value' (Un\G135) to 1 or higher. If 'CH1 Pre-scale setting value'
(Un\G135) is set to 0, the value stored in 'CH1 Sampling pulse number' (Un\G0) will be 0 due to the relationship within the
arithmetic expression for the sampling pulse number. Therefore, even if the count operation is performed, it will appear as if
the input pulses have not been counted.
