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 during the initial start-up, after change in location and variation of
surrounding temperature. To receive accurate measuring values it is also recommended to adjust the balance
periodically in weighing operation.
6.7 Adjusting (see chapter 7.2.1)
With an adjustment weight, the weighing accuracy can be checked and re-adjusted at any time.
Attention: In the verified balances the adjustment is not possible.
Procedure when adjusting:
Observe stable environmental conditions. A short warming up time of ca. 15 minutes is recommended for
stabilization.
6.8 Verification
General introduction:
According to EU directive 90/384/EEC balances must be officially verified if they are used as follows (legally
controlled area):
a) For commercial transactions if the price of goods is determined by weighing.
b) For the production of medicines in pharmacies as well as for analyses in the medical and
pharmaceutical laboratory.
c) For official purposes
d) For manufacturing final packages
In cases of doubt, please contact your local trade in standard.
Verification instructions
An EU type approval exists for balances described in their technical data as verifyable. If a balance is used
where obligation to verify exists as described above, it must officially verified and re-verified in regular intervals.
Re-verification of a balance is carried out according to the respective national regulations. The validity for
verification of balances in Germany is e.g. 2 years.
The legal regulation of the country where the balance is used must be observed!
