CALIBRATION
The flow meter and the forward speed sensor must be calibrated for correct
operation and this is done in the calibration menus.
The procedure for these calibrations follows:
FLOW METER CALIBRATION
Automatic flow meter calibration:
The TeeJet 500 Slurry computer has an automatic flow meter calibration function
and the procedure for using this is as follows:
Step/Key Description
1
If this is the first time that the flow meter is to be calibrated then
encode 1000 as the flow figure using the arrow keys.
2
Press this key (program key 1) and encode the amount of slurry in
the tank.
3
Spread the contents of the tank taking care not to allow air to pass
through the flow meter (do not empty the tank completely).
4
Press this key (program key 2) and encode the amount of slurry
remaining in the tank (Ton left).
5
Press this key (program key 4) and a new flow figure is calculated
automatically by the TeeJet 500 Slurry computer.
Manual flow meter calibration:
The flow figure can also be calculated manually and the procedure for this is as
follows:
1. Fill the slurry tank completely so that the exact amount filled is known.
2.
Reset or start a new task (see page 21).
3. Empty the tank completely (avoiding air in the flow meter).
4.
Note the amount (Ton) spread under “Trip counter” (see page 21).
5. Place the value in the following formula:
NEW FLOW FIGURE =
Old flow figure x amount spread
Amount displayed (TeeJet 500)
6. Encode the calculated result as the new flow figure.
