FLOWMETER CALIBRATION (FLOW FIGURE)
Key Function
Flow figure:
1. If this is the first time that the monitor is being used with a sprayer, encode a
"start" flow figure of 2000.
2. It is recommended to hold still when calibrating the flow meter to avoid
incorrect readings on the sprayer tank indicator. If there is any doubt as to the
accuracy of the tank indication, then weighing the sprayer will give greater
accuracy.
3. Fill the sprayer with min. 600 litres (the more the better) and note the amount
filled.
4. Reset the litre counter as follows:
Press
Press the L key once then press and hold down the 0/C key until the
litre counter is zeroed.
5. Spray minimum 500 litres.
6. Read the amount remaining in the tank using the tank indicator.
7. Calculate the consumed amount using the following formula:
CONSUMPTION FROM TANK = Amount filled – Volume remaining in the tank
8. Insert the consumed amount in the following formula:
Old flow figure x Consumed litres
NEW FLOW FIGURE =
Amount displayed (litre counter)
9. Encode this new value as the new flow figure.
NOTE! If the percentile deviation of the flow meter is known, the calibration
figure can be altered using the +/-% key. Each time the key is pressed
the sign will be altered. The flow figure can only be altered in whole %
using this key.
