11.0 CALIBRATION
The CBC-M approved scales are sealed to prevent unauthorised
calibration. Contact Adam Equipment or your supplier for more details.
11.1 CALIBRATION PROCEDURE
The calibration of the CBC-M scale is
accomplished by removing the label at
the base of the scale which covers a
hole through which the PCB can be
accessed. If your scale is not provided
with this hole, you need to break the
security seals and remove the top
cover to gain access to the circuit
boards inside. See the figure on the
security seal below.
WARNING: CALIBRATION OF THE SCALES MAY MAKE IT ILLEGAL TO USE
THE SCALES FOR SALES OF GOODS. CONTACT YOUR TRADING
STANDARDS OFFICE FOR FURTHER ASSISTANCE.
11.2 SECURITY SEALS
To seal the scale a lead-wire seal can
be used as shown below. The base has
a metal pin that protrudes through the
cover. The security seal may be
threaded through this metal pin, making
it impossible to remove the cover
without damaging either the security
seal or the enclosure.
Metrology labels and additional security
measures may be added to the scale as
required by the national legislation.
An alternative method of sealing the scales is to have a seal covering the joint
between the base and cover. If this seal is broken the scale must be sealed by the
relevant authorities, using either the lead wire seal or an acceptable seal between
the cover and base.
