Verification information
An EU qualification approval is available for those balances marked as appropriate
for verification in the technical data. In the event that the balance is applied in an
area subject to verification as described above, it must be officially verified and re-
verified at regular intervals.
Re-verification of a balance is carried out in compliance with the respective legal
provisions of the states. The term of verification validity for balances in Germany, for
example, is normally 2 years.
The legal provisions of the country of use are to be observed.
After verification the balance is sealed at the marked positions.
Verification of the balance is invalid without the seal.

Balances with obligatory verification must be taken out of service if:
- The weighing result of the balance is outside the maximum limits of
operating errors. Therefore load balance is regular intervals with known test
weight (ca. 1/3 of the max. load) and compare with displayed value.
- The date for subsequent or periodical verification has passed.
