7.6 Adjustment with external weight
As the acceleration value due to gravity is not the same at every location on earth,
each balance must be coordinated - in compliance with the underlying physical
weighing principle - to the existing acceleration due to gravity at its place of location
(only if the balance has not already been adjusted to the location in the factory). This
adjustment process must be carried out for the first commissioning, after each
change of location as well as in case of fluctuating environment temperature. To re-
ceive accurate measuring values it is also recommended to adjust the balance peri-
odically in weighing operation.
Procedure when adjusting:
In calibrated balances the adjustment function is switch locked.
To carry out calibrations, you will have to throw the unlock switch
Observe stable environmental conditions. A warming up time (see chapter 1) is re-
quired for stabilization. Ensure that there are no objects on the weighing plate.

Carefully place adjusting weight in the centre of the weighing plate. Adjustment will
be carried out automatically after dead stop control.
Remove adjustment weight during count down to zero.
The balance returns automatically into weighing mode. An error message will ap-
pear on the display should a adjustment error occur or should the adjustment
weight be incorrect. Turn balance off, then restart it and repeat the adjustment
process.
