STEP %
Enter your desired percentage figure. (one entry only for +/-%) (max figure = 99%).
LITRE LEFT
To see how much is left in the tank, you must encode the amount filled into the
tank here.
If there is an amount remaining in the tank when filling, this amount must be added
to the amount filled thus:
Amount remaining in tank + amount filled = Litre left.
NOTE!
If the optional fill-flow equipment is fitted, LITRE LEFT is encoded
automatically
HA LEFT
As above, you must enter the field size before commencing work. (End time &
required fill amount are calculated from this parameter).
FLOW-FIGURE
This is the "calibration-figure" for your flowmeter.
In other words: The measuring accuracy of the liquid! You MUST calibrate your
flowmeter. Recalibrate the flowmeter if the consistency of the liquid used changes.
FLOW CALIBRATION
Encode (LH20 D meter) a "start" figure of 2000.
Method 1. (The computer calibration-mode)
(Just follow this instruction and those on the screen)!
1.
Fill the tank, or minimum 600 litres.
2. Encode the filled quantity in “LITRE LEFT”, and return to “Flow figure”.
3. Spray minimum 500 litres (All boom sections open, keep within normal
pressure range (e.g.3 Bar). You may keep the machine stationary, using the
simulated speed facility, (see "SYSTEM") or select “MANUAL” and set your
pressure (see page 13).
4. Verify the remaining litres in tank on the tank scale! (Note: machine must be
level).
5. Place the cursor on “TANK LIT” and encode the amount remaining in the
tank.
6. Press the flashing "CALC. FLOW"- key!
7. The new flow-figure is now calculated and automatically encoded.
NOTE!
If you should be uncertain regarding the accuracy of the tank-scale, it is
recommended to take the machine to a weigh- bridge for verification.
