8.2.4 Exciting Frequency
You can select an exciting frequency of 6Hz, 12Hz or 24Hz.
Since each exciting frequency value has its own characteristics, you should select an appropriate
exciting frequency (24Hz is set at shipment. Depending on the characteristics of the detector, a
large frequency may result in excitation failure. When a large frequency value is set and it changes
the indicator value, decrease the frequency to a value that will not change the indicator value.)
