5.7

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 at every start-up, after every change of loca-
tion as well as in case of fluctuating environment temperature. It is also recommend-
able to adjust the balance periodically during weighing operation in order to obtain
exact measured values.

Adjusting

5.8.1 Adjusting with externall weight (only KERN EW-B, EW-N)

For verified balances the verification switch is locked (except for class of accuracy I).
In order to proceed with the verification, please unlock the verification switch (except
for class of accuracy I).

5.8.2 Adjusting with internal weight (only KERN EG)

Adjust the balance prior to any start-up.
Using a precision weight, the accuracy of the balance can be checked at any time
and adjusted.
Adjustment procedure:
Check that the surrounding conditions are stable.
A short warm-up time of about 10 minutes is recommended for stabilisation.
