The 844 console will display a large “ US ” in the center of the display. The default
value “ US ” indicates that all default values will be shown in U.S. measurements,
unless changed to Turf ( trF ), Anhydrous ( nh3 ), Imperial Gallons ( INP ), or Metric ( SI )
units. Turf units displays information in Gallons per 1000 ft 2 , NH

and SI displays all units in metric (l/min, l/ha, km/hr, cm).
If you will be using U.S. measurements no change is necessary, depress the

Default = FLO
The 844 system can be used with either a flow meter, pressure transduce or

The default value is set for a “ FLO ” based system using a flow meter. If this is what
you have installed on your sprayer, then depress the key to advance to the
