8.1 Information for certified scales in EC countries
Weighing instruments verified at the place of manufacture bear the preceding mark on
the packing label and green "M" sticker on the descriptive plate. They may be set to
work immediately.
Weighing instruments which are verified in two steps have no green "M" on the
descriptive plate and bear the preceding identifaction mark on the packing label. The
second step of the verification must be carried out by the approved OHAUS Service or
by the W&M authorities. Please contact OHAUS Customer Service.
The first calibration step of the verification has been carried out at the manufacturing
plant. It comprises all tests according to EN45501-8.2.2. Scales with analog connec-
tion to the weighing platform require an additional test according to EN45501-
3.5.3.3. However, this test is not mandatory if the terminal bears the same serial
number as the weighing platform.
If national regulations in individual countries limit the period of validity of the certifica-
tion, the operator of such a scale is himself responsible for its timely re-certification.
