cal (calIBraTIon) Menu [20]
Quick Config got your system up and running with a calibration based on system and sensor characteristics.
The Cal menu is used to refine and improve the calibration. This section provides explanations of each of the
calibration parameters and detailed navigation procedures through the menu tree for each type of calibration.
Cal menu has five submenus:
Auto Cal
Sets Lo Span, Hi Span, and Display value Correction values while moving material into
or out of the vessel. Auto calibration will result in the highest system accuracy
Manual Cal
Manually set scale factor weight, scale factor counts, and zero counts. Use manual
calibration to fine-tune the calibration or re-enter previous calibration data.
Linearization
Sets up and turns on and off the linearization table. Use this function if the vessel’s
structure responds nonlinearly, but consistently, to changes in load, resulting in
consistent, incorrect weight readings after the system has been correctly calibrated.
Zero Tolerance set the range within which the Zero Key can be used to zero the gross weight

There are three methods for performing automatic calibration:
• High-Accuracy Calibration
• Calibration by Adding a known Quantity of material
• Calibration by Subtracting a known Quantity of material
Each method requires moving a known quantity of material, representing at least 25% of the vessel’s total
capacity, into or out of the vessel. The latter two methods do not provide as high accuracy calibration as the first
method. However, these lower accuracy calibrations can be later refined to increase the accuracy (see refining
the Calibration with the Display Value Correction in this section).
note: See Troubleshooting Section for an explanation of error messages you may encounter while performing an
Auto Calibration.
