WARNING: BINDING ON A SCALE/VESSEL OR LOAD CELL CAN DENY THE LOAD CELL FREE VERTICAL
MOVEMENT AND PREVENT THE INSTRUMENT FROM RETURNING TO THE ORIGINAL ZERO REFERENCE POINT.
ATTENTION: LIEU SUR UNE ÉCHELLE / UN BATEAU OU UNE CELLULE DE CHARGE PEUT ENDOMMAGER LE
MOUVEMENT VERTICAL LIBRE DE LA CHARGE DE CHARGE ET ÉVITER L'INSTRUMENT DE RETOURNER AU
POINT DE RÉFÉRENCE ZERO ORIGINAL.
C2 Calibration
C2 calibration requires C2 load sensors. If you do not have C2 load sensors you must perform a traditional
calibration with test weights which we call a Hard Calibration. The Weigh Module reads the performance
characteristics of each individual load cell and detects the quantity of load cell(s) in the system. C2 Calibration
can be performed by via Allen Bradley RS LOGIX 5000.
C2 Calibration Procedure:
Step 1. Place the ref weight on the scale (if not zero).
Step 2. Send the C2 calibration command (0x66) by placing the command number into the command
register in the output table.
C2 Calibration Using Ladder Logic
1.
Check to be sure that the parameters have been setup for your weighting process. (See Chapter
4, Setup & Operations)
2.
We have provided a Ladder Logix example explaining how to perform the C2 calibration. The
Ladder Logix example is available on the Hardy Process solutions Web Site:

C2 Calibration Using the Faceplate
Once the Faceplate is up and running (for faceplate set up refer to Faceplate quick start), navigate to the
calibration menu of the faceplate. Be sure to set your reference weight to the weight that is on the scale (if there is
weight on the scale, otherwise leave it at zero). Once the parameters are set make sure to save them, by clicking
on the
Save Parameters
button. Now that the parameters are set you are able to perform a C2 Calibration by
clicking on
Do C2 Cal
. The Calibration status will display once “Calibration Ok” once the calibration is finished.
