Menu 3.5 Tank gauge

General info

This menu item is only present if the HARDI Tank Gauge is fitted. For increased accuracy it is recommended to do the flow
calibration [3.2] before proceeding.
Present accuracy is up to +/- 25 litre. This is at the widest liquid surface area in the tank. The smaller the liquid surface area,
the more accurate the readout. The accuracy is also affected of the sprayer being level. Assume the height of hitch point
measured from the ground should be 550 mm, then readout of tank contents changes with the hight of the sprayer at the
hitch point. In the schematic an example of the difference in tank contents can be seen.

Menu 3.5.1 Adjustment

The correction factor for the specific gravity of the liquid sprayed can be
set.
Default value is 1.000.
For liquid fertilisers, the specific gravity may range up to 1.3 kg/L. The
value in this case would be 1.300.
Method
1. Press to change value.
2. Use and to move cursor to the figure to be changed.
3. Change figure by pressing
