17.4 LENGTH SENSOR CALIBRATION PROCEDURE
NOTE: The length sensor can be calibrated for its zero point and its full range. This means, for the
correct voltage for retracted boom and for the extended boom. With retracted boom, the
potentiometer of the length sensor has to be at its 0 position, which is all the way counter-clockwise.
For extended boom, the adjustment is done by software as described in 6 section Length Sensor
Adjustment Procedure.
The length should be calibrated to be about 0.1 feet (or 0.05m for metric) accurate for retracted and
extended lengths. Perform the following steps:
Fully retract the main boom and check if indicated length is within 0.1’ of actual retracted boom length.
If it is not, adjust length potentiometer as described in 6.3.1. Afterwards always adjust retracted length
by software as described in section Length Sensor Adjustment Procedure.
