Scale parameters and functions8.4 Calibration procedureSIWAREX WP23180 Manual, 07/2014, A5E31238908A-028.4.2 Automatic calibrationScales can be rapidly commissioned with automatic calibration. The accuracy of the scalegreatly depends on the entered parameters and the mechanical properties of the scale. Thebest level of accuracy for the scale can be achieved by calibrating with calibration weights.During initial commissioning with automatic calibration, the module must be reset using the"Load factory settings" or "Load standard parameters" command.The load cell parameters must subsequently be defined in data record 10. Command 82"Perform automatic calibration" then uses this data and the currently applied dead load tocalculate the characteristic curve of the scale. The characteristic curve is active immediately.NoteThe characteristic curve data in data record 3 active prior to execution of command 82 isdirectly overwritten.Automatic calibration requires the following criteria:● Correct mechanical installation of the scale● Scale is empty (only mechanical installation (= dead load) present on the cells)● Installed load cells are evenly loaded● There are no shunt circuits
