TEMPERATURE
Temperature range: between 15 – 105 ºF (-10 - +40 ºC) the maximum inaccuracy is
0.1% of the weighed load. Outside this range inaccuracies of up to 0.3% may occur.
Fast temperature changes must be avoided because it can cause condensation in
the electronics. During acclimatization the weighing system must be shut off.
MAINTENANCE
The maintenance guidelines for normal electric pallet trucks apply to the chassis of
the mobile weighing system. The integrated weighing system still functions even
when the chassis is damaged by overloading. Care should be taken to prevent
damage to the load cells.
Main guidelines:
- Clean only with a damp cloth. Chemical cleaners and high pressure washers will
cause damage to the system. System should be cleaned regularly to remove any
accumulating dirt between the parts of the system.
- Check bolts regularly. When used roughly, they may loosen.
- The weighing system meets up to the protection class IP65. This means that dust
or moisture (rain or water beam from all sides), will not influence the operation of
the electronics. However, high-pressure cleansing in combination with warm water
or chemical cleansers will lead to the entry of moisture and therefore negatively
influence the operation of the system.
- Only specialists may perform any welding. This is to avoid damage to electronics
and load cells.
