1.0 INTRODUCTION The AZextra series of digital price-computing scales provide an accurate, fast and versatile method of computing price by weight. These series of scales are EC approved for the use in UK and Europe. For all revisions from 2.29 and above, the Price per kilogram and per 100 gram [Kg 100g] key can be disabled at the factory for the scales to be used in South Africa and Far East.
5.0 CALIBRATION CALIBRATION PROCEDURE The scales are sealed to prevent unauthorised calibration. Contact Adam Equipment or your supplier for more details. The calibration of the AZextra scale is accomplished by removing the label at the base of the scale which covers a hole through which the PCB can be accessed.
The EC approved models should follow the requirements of the Metrological authorities to have the scale verified for use after calibration. If calibration is not possible, the load cells or PCBs may have been damaged. Contact Adam Equipment or the supplier. 6.0 SERVICE PARAMETERS USING “0000” TO ENTER THE CALIBRATION PARAMETER Calibration can be enabled by placing a jumper into the pins on the main PCB (marked as position J4) through a hole provided on the base of the scale.
