6.7 Adjustment

As the acceleration value due to gravity is not the same at every location on earth,
each display unit with connected weighing plate 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 weighing system 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 display unit periodically in weighing operation.
•
The adjustment is locked for verified balances.
In order to unlock the access, the seal must be destroyed and the
jumper on the printed circuit board must be fitted (see chap. 6.9).
Attention:
After destruction of the seal the weighing system must be re-verified by
an authorised agency and a new verification wire/seal mark fitted before
it can be reused for applications subject to verification.
•
The weight to be used depends on the capacity of the scale. Carry out
adjustment as near as possible to the scale's maximum weight. Info
about test weights can be found on the Internet at: http://www.kern-

•
Observe stable environmental conditions. Stabilisation requires a
certain warm-up time.
