Custom calibration
1.
First enter menu [3.5.3.01 Custom calibration of gauge].
2.
Go to menu [3.5.2.1 Water level].
3.
Fill the sprayer up to nominal tank contents, using an external
calibrated flowmeter. Alternatively weigh the sprayer before and
after filling, and note the weight difference.
4.
Press Enter.
˜
ATTENTION! As the accuracy of the custom calibration is affected,
it is of high importance that the external calibrated flowmeter
measures the correct quantity within a 2% deviation. Same
accuracy of 2% must be kept if weighing the sprayer before/after
filling is used.
±
WARNING! Do not leave the sprayer while filling the tank, and keep an eye on the level indicator in order NOT to
overfill the tank.
5.
Press Enter after ensuring the sprayer is level. Refill the tank up to
the tank lid if the sprayer is re-levelled.
˜
ATTENTION! Levelling the procession of sprayer is of great
importance as the accuracy is directly affected!
Assuming that the same tractor will be used after custom calibration, it
is not necessary for the sprayer to be level itself. But the whole
procession of tractor and sprayer (A) need to be level.
Use e.g. a beam (B) approximately 20 feet long, placed on two wooden
blocks at the location where the calibration will take place. Place a level
(C) on the beam (B) to find the level point of the calibration location.
