844-E Sprayer Control
Step 4 – Measure
Turn controller on and activate pump. Toggle on the Master Boom Switch and the number of boom sections to be measured. Insure that the
pressure at the boom is maintained at 40 psi (2 bar). While spraying press and hold the Program key in. Look at the lower right display to see
if the measured flow matches the calculated flow.
Step 5 – Adjustments
If the measured flow does not match the calculated flow, the flow meter number may need to be adjusted. If the measured flow is higher than the
calculated flow, the flow meter calibration number needs to be decreased. If the measured flow is lower than the calculated flow, the flow meter
calibration number needs to be increased.
Example: Calculated flow is 4.00 gPM (12.9 LPM)
{3.20 Imp gPM}; measured flow is 3.6 gPM
(11.6 LPM) {2.88 Imp gPM}
Decrease the flow meter calibration number by 10%. If original number was 650, enter 585 for this programming value.
