Example) When pulses are to be output per same liter in a span of m 3 /h,
select "m UNIT/P" since a L(liter) = 10 -3 ×
m 3
Set the low cut range percentage in parameter "F03".
Range of setting : (0 to 100% of span)
Select "Pulseoutput" in parameter number "B10".
Select the volume unit for the pulse weight in parameter number "B04".
Select the pulse width in parameter number "F04"
Set the pulse weight "10 (L)" in parameter number "F02".
*Since parameter number "F02" is a 5-digit data item, scrolling is
necessary to display all the data. Mind the decimal point when seting are
made. (The decimal point can be moved if required.)

Nor mally, these are all required settings.
The following settings are made depending on the application that is used.
Select instantaneous flow rate data or damped flow rate data for the pulse
output calculation.
(The damped value is the value set in “B02”.)
Set parameter “N02” to “OFF” when the pulse output transistor is to be
active in the off mode.
