5.3 CALIBRATION PROCEDURE
The scales are sealed to prevent unauthorised calibration.
To calibrate the scales, access to the PCB inside is needed to place a jumper in K6
position. This is done by removing the tamper-proof label placed on a hole at the bottom of
the scale. Through the hole, pick up the jumper (the jumper will be there placed on one of
the pins on the PCB) and place it in the desired K6 position. If the hole is not provided in
your scale, the security seal has to be broken to remove the top cover and gain access to
the main PCB. Replace the cover and install the screws before starting the calibration.
