EW/EG-KB-e-9811 134 SECTION 4. ADJUSTMENTS AND SETTINGS4.1 Span calibration (Cal) - EW type1. It is recommended to use a calibration weight ofbetter accuracy than the scale.2. The calibration is available with ½ of F.S.Nevertheless, it is recommended to use weight closerto F.S. for accurate calibration.3. Error messages:0 - E r r : The calibration weight is over the full capacity.1 - E r r : The calibration weight is less than ½ of the capacity.2 - E r r : The data error exceeds 0.4%.Or perhaps the scale may be defective.
