SERVICE CALIBRATION
This section describes the Service Menu and sub-menus, which allow authorized service
personnel to perform factory Linearity and Span calibrations (no pre-set limits).
Note:
Be careful not to touch the scale or the surface it rests on while calibration is in
progress, as it will cause the process to fail.
