(14) Dividing function
The dividing steps down the input pulse to one-tenth or one-hundredth. If the dividing is stepped down to one-
tenth, 1 is counted every 10 pulses. For the dividing, input dividing and output dividing are available. The input
dividing executes dividing before the pulse from flowmeter enters the counter. The output dividing divides the
external output pulse.
(13) Display of cumulative total flow unit
The cumulative total flow unit can be displayed in the upper right of total display part (parameter item 16).
The types of units to be displayed are shown below.

Scaler:
If the flowmeter input pulse unit is unscaled, set it to correction pulse using a scaler.
Do the calculation with CPU.
Input dividing:
Step down the input pulse to one-tenth or one-hundredth.
Thus, in case of one-tenth, for example, the counter counts 1 while the input pulse counts
10.
Do the calculation with CPU.
Arithmetic processing: As the calculation is processed by software of CPU, scaler / dividing function is realized
by calculation formula shown below.
Display counter = internal counter x scaler value x input dividing value
The fractional number after decimal point of calculation result should be cleared for each
batch for both of counter for batch and counter for integration.
For the output pulse multiply the output dividing value furthermore.
Input synchronization: Function for dividing only the counter value of batch counter and outputting the input
unscaled pulse for the output pulse
It is functioned by setting parameter of output dividing.
