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 to
calculate the characteristic curve of the scale. The characteristic curve is active immediately.
Note
The characteristic curve data in data record 3 active prior to execution of
command 82 is
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
DR 4 Output of calculated calibration digits
8.5.1
Data record DR 4 outputs the digits calculated from the automatic scale calibration and the
calibration check. This data record cannot be sent to the scales.
