6. PARAMETER DESCRIPTION

[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 m3/h, the second range = 100 m3/h, and the Pulse Low Cut = 3%, no pulse output is carried out at flow rates of 0.3 m3/h or lower.

[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”.
