4.1 Please note that load cells may be damaged because of (shock) overloading, lightning strikes or
heavy surges. Also current, chemical or moisture ingress, mishandling ( dropping, lifting with cable,
etc), vibration, seismic events or internal component malfunction, may cause the loadcell to be
damaged. Inspect the loadcells before and after every season. Give special attention to critical areas
of the load cell such as metal bellows, seals etc. Regularly inspect for corrosion damage to the load
cell and mounting hardware. If practically possible, carry out cleaning and perform remedial work
(paint or other protective coating). Do not allow build-up of debris around load cells or mounts.
