FLOW RATE FEATURE

The 844 Sprayer Control will measure a flow rate moving through the flow meter
in GPM (LPM) {Imp GPM}. This feature is activated by pressing and holding the

key while spraying in the normal operating mode. The flow rate display

replaces the area/volume display in the lower right portion of the display.

Any time the key is pressed while spraying in the normal operating mode the
flow rate will be displayed. Releasing the key will cause the display to return
to area/volume.

This feature can be used for tip calibration or for calibrating the flow meter.
Refer to page 38 of this manual for flow meter calibration procedures.

NOTE: Not all 844 models contain this feature. If the display makes no
change when pressing on the key while spraying in the normal
operating mode, then this feature is not available with this console.

APPLICATION ALARM

If the 844 senses a continuous discrepancy of 10% or more between the Target
Application Rate and the Actual Application Rate, the application rate units (GPA,
G/1000 ft

or l/ha) will flash in the display window. This alarms the operator to a

problem with the sprayer plumbing, operation or programming.

NO FLOW ALARM

If the 844 stops receiving pulses from the flow meter, the symbol will flash
at the top of the display. This alarm indicates that the flow meter has stalled and
alerts the operator that there is a problem with the flow meter or elsewhere in
the system.

This alarm will occur only when the Master Boom Switch and at least one boom
toggle switch is “on”.
