Not available for WBZ Scales.
12.0 CALIBRATION
12.1 CALIBRATION PROCEDURE
The scales have methods to either prevent or control unauthorised
calibration. If the Calibration Counters are enabled the scales can be
calibrated without breaking the seals, however the counters will be
incremented to identify a calibration or change in parameters.
If the scales do not have the counters enabled then access is controlled by
breaking the seals on the scale to gain access to the circuit boards inside.
See the figures on the security seal as given below.
WARNING: BREAKING OF THE SEALS MAY MAKE IT ILLEGAL TO USE
THE SCALES FOR SALES OF GOODS. CONTACT YOUR TRADING
STANDARDS OFFICE FOR FURTHER ASSISTANCE.
12.2 SECURITY SEALS
Method of sealing
Alternative method
The scale has got metallic loops on the base
and the cover, located at the right rear corner
as shown here. A metal pin or wire can be
passed through the loops and sealed using a
lead-wire seal. Ensure the seal is secured
enough to prevent removing the cover
without breaking the seal or damaging the
enclosure.
