4.0 OPERATION
Please refer to the User Manual for the details on operation.
5.0 CALIBRATION
5.1 CALIBRATION PROCEDURE
The scales are sealed to prevent unauthorised calibration.
Contact Adam Equipment or your supplier for more details.
The calibration of the AZ
extra
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.
5.2 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.
