13.3.3 Angle Sensor Calibration Procedure
After completing steps 1 through 4 at the beginning of this section, boom down to a flat angle and
mechanically adjust the angle sensor. The angle should be set to be +/-0.0 of the measured angle.
Material – calibrated inclinometer.
Note: the displayed angle indication is noted
by XX.X in following steps.
Press “OK” when the sensor is mechanically set.
Pressing “OK” confirm the mechanical adjustment.
Boom up to the next correction angle, 40 DEG (range 35°- 45°). Note: When the boom angle is within
the calibration range, the screen will add the ‘CHANGE’ and ‘OK’ text to the screen similar to the
screen below. Measure the boom angle with the inclinometer and when the boom is positioned in the
calibration range, compare the measured angle to the displayed angle.
Use the ‘UP’ and ‘DOWN” arrow buttons to select “CHANGE” then press ‘OK’. The displayed angle
should now be flashing.
Use the ‘UP’ and ‘DOWN” arrow buttons to adjust the indicated angle to match the measured angle.
After the display shows the correct angle, press ‘OK’.
After ‘OK’ is selected the system defines a high boom correction angle, 70 DEG (range 65°- 75°).
Complete the above procedure to set the correction factor at high boom angle.
After ‘OK’ the system request the angle sensor calibration be saved.
Use the ‘UP’ and ‘DOWN” arrow buttons to select ‘YES’, which should be flashing then press ‘OK’ to
confirm calibration.
Press EXIT to leave calibration or select the ‘CALIBRATE SENSORS’ to calibrate another sensor.
