3.3 Length sensor calibration procedure
NOTE: The length sensor can be calibrated for its zero point and its full range.
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 below.
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:
▼ Start screen zero point adjustment, boom length:
leave the service menu
Start length calibration
▼ Start screen min. boom length:
leave the service menu
skip calibration step / go to next menu
• Fully retract the main boom and check if indicated length is within 0.1 feet (or 0.05m for metric) of
actual retracted boom length.
• If it is not
, adjust length potentiometer mechanically as described below:
