Verification instructions
An EU type approval exists for balances described in their technical data as verifiable. If a
balance is used where obligation to verify exists as described above, it must 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!
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 reg-
ular 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.
