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 +/- 13 gallons. This is at the widest liquid
surface area in the tank. The smaller the liquid surface area, the more
accurate the readout.
Menu 3.5.1 Adjustment of specific gravity
The correction factor for the specific gravity of the liquid sprayed can be
set.
Default value is 1.000.
Corrected value is weight of solution divided by weight of water.
Liquid fertilizers may range up to 1.3 times heavier than water. 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 ¿ and ª. Alternatively key in on the numeric keys.
4. Confirm setting by pressing #.
Menu 3.5.2 Custom calibration of Tank gauge
Calibration of the HARDI® Tank Gauge is necessary if the factory
calibration proves inaccurate. This can be due to different placed hitch
point on the tractor or different tire mounting resulting in an inaccurate
calculation of the tank contents.
Therefore, it is recommended to begin the custom calibration by
connecting the sprayer to the tractor that will be used for spraying. Later
changes of tractor can affect the accuracy of the Tank gauge.
To make a custom calibration of TankGauge, do the following:
1. First enter menu [3.5.3 Select factory calibration]. Then select the
submenu [3.5.3.01 Custom calibration of gauge].
