[ 02 ] Flow calibration - Tank method
During practical flow calibration in menu 02, the tank is partly emptied
through the nozzles. Whilst emptying, the display calculates the quan-
tity 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
difference before and after. The quantity displayed is corrected to read
the quantity actually dosed.
Method
1. Place the tank on level ground and fill up with water until the level
reaches a unique mark on the tank contents level indicator, e.g.
1000 litre / 300 gallons.
2. Open all boom sections.
3. Open menu 02 and turn the main ON/OFF valve on. [

will be displayed if there is no flow. The display unit will then begin
to count the volume being emptied through the nozzles.
4. When for example, 600 litre / 200 gallons have been emptied out, as
shown by the tank contents level indicator, the main ON/OFF valve
can be turned off.
5. 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 briefly show the new calibration value PPU (pulses per unit)
when returning to the main display picture.
