4 - Calibration procedure
The machine is equipped with a 2 channel load cell type weight management system, mounted between the platform
and the boom assembly.
The location of the load cell means calibration is required when the system values become out of correct range, or
when any of the platform sub assembly components (cage, support, flooring etc) are replaced.
The system can be recalibrated in 3 ways depending on the software version :
• Reset of the Zero (empty cage) value.
• Calibration using a fixed known weight of 250 kg (551 lb).
• Calibration with a known weight of any value between 50 kg (110 lb) and 300 kg (662 lb).
