Maintenance - Mettler Toledo BTA226 Serie Bedienungsanleitung

The weight must be lifted freely: without touching the housing of the indicator or other
pallets:
Wrong way of lifting the load
The accuracy of the weighing system diminishes with circa 0.1% per degree starting
from a tilted position of 2°. This effect also occurs with pits/pot-holes in the floor. An
even floor is optimal.
The most accurate weighing result is obtained when the centre of gravity of the load
is placed between the forks. With an non-centric loading, the forks will tordate and
bend. This may result in a higher inaccuracy.
Non-optimal placement of the load
Temperature range: between -10 and +40° C 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 will cause condensation in the
electronics. During acclimatisation the weighing system must be switched off.

2.3. MAINTENANCE

The maintenance guidelines for normal pallet trucks apply to the chassis of the
mobile weighing system. From experience we know that the integrated weighing
system still functions when the chassis is damaged by overloading.
Main guidelines:
- Because the steering wheels are mounted in the front, pulling of the pallet truck is
preferred above pushing it.
- When the lifting mechanism is not used, the handle should be kept in the neutral,
middle, position. This prolongs the life span of the sealings.
- 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 undertake any welding. This is to avoid damage to
electronics and load cells.
