General information:

the following way (legally determined scope):
a) for commercial purposes when the goods' price is determined by weighing
them,
b) to produce medications in pharmacies and also for analyses in medical and
pharmaceutical laboratories,
c) for official purposes,
d) for manufacturing finished packagings.
In the case of any doubts, contact the local Office of Measures.
Guidelines concerning verification
The scale which is marked verifiable in the technical specification holds a type
approval certificate in force in the European Union. If the scale is to be used in the
above-mentioned area requiring verification, it must be verified and its verification
must be renewed on a regular basis.
Re-verification of the scale is carried out in line with the regulations in force in a given
country. E.g. in Germany the scale verification validity period is usually 2 years.
Always follow the regulations in force in the country of use!
Once the verification process is completed, the scale is sealed in the determined
position.
Scale verification with no "seal" is invalid.
Seal location (PLJ models)
The verifiable scales should be removed from operation if:
The scale weighing result is outside the permissible error limit. This

is why the scale should be loaded with the reference weight of a known
weight (ca. 1/3 of the Max load) regularly and the displayed value should
be confirmed with the reference weight.
The re-verification deadline is exceeded.
