"MANUAL" SPEED CALIBRATION.
E.g. when sensor is fitted to a wheel:
1.
Mark the wheel (e.g. the valve), and mark the field.
2. Drive the machine exactly 10 revs, of the wheel.
3. Mark out on the Field.
4. Measure the driven distance carefully (to nearest cm). Calculate your
calibration figure. Use the following formula:
Example:
The measured distance between marks = 52.80 metre (5280 centimetre)
The wheel turned 10 revs.
Four (4) magnets are fitted.
5280 (the distance driven in cm)
10 (the revs.) X 4 (the magnets )
= 132.000 cm
This figure: (132) is to be encoded. Press function-key "WHEEL TRACTOR".
Encode 1 - 3 - 2 using the numerical keypad.
Incorrect encodements can be deleted using the "C"-key.
"Manual" speed calibration e.g. sensor fitted to a prop-shaft
1. Press the function-key : "CALIB CALC". The
screen to the left will appear:
2. Move (drive) slowly. Stop when "NO OF
PULSES" changes from "0" (nil), to "1".
3. Mark the field.
4. Drive slowly. Stop when NO OF PULSES"
changes from "50", to "51".
5. Mark the field. Measure the distance between
the two marks.
6. Divide the measured distance (cm), by 50.
7. Encode the result (in cm.) using the numerical
keypad.
TANK VOLUME
The sprayer’s tank size is encoded here. This is required if the automatic tank fill
feature is to be used.
