Verification instructions
An EU type approval exists for balances described in their technical data as verify-
able. 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 regula-
tions. 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!
Balances with obligation to verify must be taken out of operation if:
•
The weighing result of the balance is outside the error limit. Therefore, in
regular intervals load balance with known test weight (ca. 1/3 of the max. load)
and compare with displayed value.
•
The reverification deadline has been exceeded.
