Carefully place calibration weight in the centre of the weighing plate. Calibration
will be carried out automatically after dead stop control.
Remove calibration weight during count down to zero.

appear on the display should a calibration error occur or should the calibration
weight be incorrect. Turn balance off, then restart it and repeat the calibration
process.
* The calibration should be made with the recommended calibration weight (see
chap. 1 "Technical data" in the operating manual).
