Adjustment - KERN GAB-N Operating Instructions Manual

9 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.
•
For verified balances the adjustment is locked. In order to access the
menu you will have to short-circuit the two contacts of the circuit board
with a jumper (See chpt 9.3).
Attention:
After destruction of the seal the balance 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.
Observe the verification notes (see chapter 9.3).
•
The weight to be used depends on the capacity of the balance. Carry
out adjustment as near as possible to the balance's maximum weight.

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