Verification testVerification test

The weighing instrument is verified if

• the accuracy class is displayed in the metrological line,

• the securing seal is not tampered with,

• the validity is not expired.

The weighing instrument is also verified if:

• ‘Approved scale’ is displayed in the metrological line,

• Labels with the metrological data are placed near the weight display,

• The securing seal is not tampered with,

• The validity is not expired.

The period of validity is country-specific. It is in the responsibility of the owner to renew verification in due time.

Combinations of a weighing terminal and an analog weighing platform use a Geo Code to compensate for gravitational influence. The manufacturer of the weighing instrument uses a defined Geo Code value for verification.

Please check if the Geo Code in the instrument corresponds with the Geo Code value defined for your location. The Geo Code value is displayed when you switch on the instrument. The Geo Code for your location is shown in the appendix.
