If the balance does not show exactly zero although the pan scale is unloaded, press
the TARE-button and the balance will be reset to zero [ a ].

6.5.4 Auto-zero-function

6.6 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. It is
also recommendable to adjust the balance periodically during weighing operation in
order to obtain exact measured values.
