Not Available On The PC Menu H330 Units [Ft CW ]
This option is used to set the units the stage value will be reported in. The H-330/H-331 has a
resolution of 200 counts per revolution. Using a 1.0 foot circumference pulley equates to 200
counts per foot. The default slope value of 0.005 per count will report each complete turn as one
foot of water level change. The user can change the units to one of two predefined options or
select a user defined value. The available options are listed below.
Ft CW: This uses a slope of 0.005 and will report water level in feet based on the pulley
turning clock wise for an increase in water level.
Ft CCW: This uses a slope of -0.005 and reports water level in feet based on the pulley
turning counter clock wise for an increase in water level.
User Def: This will open a new menu screen allowing the user to enter in any slope value
desired. This could be used to report the stage in meters, inches, etc.
Remember these settings are programmed into the H-330 or H-331, not the XL™.
