6.8 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.
How to carry out adjustment:
 Unverified weighing systems, see chapter 11
 Verified weighing systems, see chapter 19.3
6.9 Verification
General introduction:
According to EU directive 90/384/EEC or 2009/23EG 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 notes:
An EU type approval exists for the appliance described in its technical data as
verifiable. If the appliance is used where obligation to verify exists as described
above, it must be verified and re-verified at regular intervals.
Re-verification of an appliance is carried out according to the respective national
regulations. Normally the validity for verification in Germany is e.g. 2 years.
The legal regulation of the country where the balance is used must be observed!
Verification of the device is invalid without the seals.
The seal marks / verification wire attached on verified appliances point out
that the appliance may only be opened and serviced by trained and
authorised specialist staff. If the sealing (paper seal/ verification wire) is
damaged, the verification validity expires. Please observe all national laws
and legal regulations. In Germany a re-verification will be necessary.
