nozzles. Whilst emptying, the display calculates the quantity emptied
on the basis of the actual calibration value (PPU). The quantity dis-

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.
