Tank method
During practical ow calibration the tank is partly emptied through the noz-
zles. Whilst emptying, the display calculates the quantity emptied on the basis
of the actual calibration value (PPU). The quantity displayed is compared with
the quantity actually dosed.
This can be according to the tank contents level indicator or by weight dier-
ence before and after. The quantity displayed is corrected to read the quantity
actually dosed.
Method
1. Place the tank on level ground and ll up with water until the level reaches
a unique mark on the tank contents level indicator, e.g. 1000 litres.
2. Open all boom sections and, if tted, close end nozzle.
3. Open menu and set the main ON/OFF to ON.
4. Engage the P.T.O.
The display unit will then begin to count the volume
being emptied through the nozzles.
5. When for example, 600 litres have been emptied out, as shown by the tank
contents level indicator, the P.T.O. can be disengaged.
6. Correct the volume shown on the display with the arrow key to read the
volume shown on the tank contents level indicator. The display will briey
show the new calibration value PPU when returning to the main display
picture.
