3-4 : Drop out
Adjustable from 0 to 10% of setting range. This function is used to set the dropout
value for the pulse output. The pulse output will be cut off below the setting value to
avoid flow pulsation in range value close to zero, thus preventing incorrect totalization
of the flow rate. Pulse counting pauses when the flow rate reaches this preset
percentage of the set range. Drop out is set by adjusting variable resistor. Default
setting is approximately two percent. If pulse is still output even though the valve is
shut off, fluid may pulsate. Set the drop out value as approximately five percent.
