A limit applies to the maximum pulse scale that
can be set with respect to the pulse width. If a
value in excess of this limit is set, a setting
alarm will be displayed.
[E13: Pulse Low Cut] Setting of the pulse output
stop range
This parameter allows the settings to be made which
prevent pulse output when the flow rate is at or below
the low-cut setting value. In cases where there are
multiple ranges or forward/reverse ranges, low cut is
carried out at the setting value for the smallest span
(i.e., an integer between 0 and 10%).
Example: When the first range = 10 m

/h, the second
range = 100 m

/h, and the Pulse Low Cut =
3%, no pulse output is carried out at flow
rates of 0.3 m

[E20: Pulse Active Mode] Setting of active mode
for pulse output
This parameter sets whether pulse-output active mode
is to be “On Active” or “Off Active”.
