How do I make a material calibration?
• Navigate to the CALIBRATION menu.
• Enter the material name and your production parameters.
• Start calibrating. The following screen appears:
• The calibration will take approximately three (3) minutes but can take longer depending on the material
used and production parameters.
It is possible to stop
the calibration to refill the hopper, for example.
To continue, select “YES” and press “Enter”. To stop, select “NO” and press “Enter”.
• The calibration will automatically finish and save after the setpoint is within the set calibration deviation
(Cal dev: default = 5%) set in the CONFIGURATIONS menu. (See Chapter 7.4)
• The control will automatically go to the PRODUCTION menu and the stored calibration will be selected.

Stored material curves have a * after the filename.
During the calibration the TrueFeed is adjusting to its setpoint. When the setpoint is reached, the calibration
will be saved. A complete material calibration curve is made on the basis of default pre-programmed curves.
Material Calibration
You can also save the actual material calibration during a running production process.
This function is called “Save data Function”. (See Chapter 7.8 for more information)
How can I select a calibrated material?
When one or more material calibrations are made, one can be selected as follows:
• Navigate to the PRODUCTION menu.
• Use the cursor to go to Material.
• Press the “Enter” button for two (2) seconds. A list will appear with stored material calibrations
• Select one with the arrow buttons and press “Enter”.
If the material calibration made is not in the list, enter the first letters of the calibration name and press “Enter”.
Now a filtered list appears. To go back to the main list, fill in the selection with spaces and press “Enter”.
It is also possible to fill in the material description immediately in the PRODUCTION menu and press “Enter”.
The message “Material not found, select new material” appears when a false material is filled in. To clear
the description, fill in the selection with spaces or select an empty calibration out of the list and press “Enter”.
How can I delete or rename a calibrated material?
To delete one or more material see Chapter 7.13.
To delete all Materials, select master reset MATERIAL in the CONFIGURATIONS menu and press “Enter”.
