Encode the size of the field to be sprayed here. END TIME, REST DOS., REST
METRE and FILL VOLUME are calculated from this encodement.
FLOW FIGURE
This figure is the calibration figure for the flowmeter. For normal flowmeters (20-
200 l/min) encode a value of 2000. See the recommend flow figure for other
flowmeters.
CALIBRATION:
Use a “start value” of 2000 as the flow figure.
Method 1: (automatic).
1.
Fill the sprayer with min. 600 litre (the more the better).
2. Encode the filled amount in “LITRE LEFT” .
3. Spray a minimum of 500 litre (spray with all boom sections open in the
normal pressure range).
4. Read the amount left in the tank using the sight gauge on the sprayer.
5. Encode the above amount left in the tank in “TANK LIT” .
6. Press the flashing “CALC: FLOW” key.
7. The new flow figure has now been calculated.
NOTE: Greater accuracy can be achieved by weighing the sprayer
before and after spraying or by conducting a jug test and
comparing the flow in L/MIN.
Pressing the flashing “CALC. FLOW” key will always calculated a new flow figure.
Method 2: (Manual):
1.
Fill in min. 600 litres (the more the better).
2. Zero the LITRE counter in DATA/DELETE .
3. Spray 500 litres.
4. Read the consumed amount on the indicator on the tank.
5. Read the LITRE counter in DATA/DELETE .
6. Insert the values in the following formula:
Old flow figure x Amount sprayed
NEW FLOW FIGURE =
Read litre counter (TeeJet 5000)
Encode this new value as the new flow figure.
NOTE: Check this calibration at regular intervals if the sprayer is fitted with a
standard TeeJet AGRO paddlewheel flowmeter.
This check is always easy with the TeeJet 5000, as the amount sprayed
should be the same as what the TeeJet 5000 displays.
Changing the paddlewheel in the flowmeter is recommend every other
year.
