5.5 Initial Commissioning

In order to obtain exact results with the electronic balances, your balance must have
reached the operating temperature (see warming up time chap. 1). During this
warming up time the balance must be connected to the power supply (mains,
accumulator or battery).
The accuracy of the balance depends on the local acceleration of gravity.
Strictly observe hints in chapter Adjustment.

5.6 Adjustment

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
receive accurate measuring values it is also recommended to adjust the balance
periodically in weighing operation.

5.7 Adjusting

The adjustment should be made with the recommended adjustment weight (see
chap. 1 "Technical data").
