● Load cell manufacturer
The manufacturer of the installed load cells can be quickly and easily identified in a
service case.
● Load cell order number
The order number of the installed load cells can be quickly and easily identified in a
service case.
7.3.5
Complete automatic calibration
● The scale must be empty (only mechanical dead load).
● Activate the "Automatic Calibration (82)" command.
7.3.6
Receive all data
Activate the "Receive all data" function in the communication menu.
All parameters can now been saved as a backup file on the hard disk. If a module is
replaced, the backup file can be downloaded to the new module within a few seconds. At the
time of input of the backup file, the scale is directly in the calibrated state again – without a
new calibration.
7.3.7
Checking the scale after calibration
Perform the following steps:
1. Scale is unloaded and shows "0 kg".
2. Place a known reference weight on the scale.
→ Check the displayed value.
3. If a second known reference weight is available, place it on the scale additionally.
→ Check whether the scale displays the sum of the reference weights.
4. Remove the reference weight from the scale.
→ Check that the display is "0 kg" again.
Should these steps not yield the expected results, the electrical connection of the load cells
and the scale mechanics must be checked.
