This section describes C2 or eCAL and traditional calibration procedures. For the Weight Processor Modules to give precise
readings, they must be routinely calibrated both during operation or when it has not used for an extended period of time. It is
important that users and service personnel be familiar with the procedures in this chapter before installing or operating the HI
6600 WPM modules.
All calibration is done in the Gross mode. Be sure to follow all the procedures completely to insure that the
weights read by the unit are accurate.
In some incidents it is better to verify a calibration than just re-do the calibration. If during the scale verification, it
is found to be out of calibration, check for damage and a mechanical problem. When all checks OK, then
recalibrate. Perform a calibration and perform a scale verification. No calibration process ensures the load cells are
functioning or installed correctly.
Always verify your scale after any calibration and maintenance routine.
NOTE: Do not perform a calibration while an application is in operation.
Pre-Calibration Procedures
Verify that the load cells have been properly installed.
 Refer to your load cell operations and installation manual for proper installation instructions.
 On some sensors and cells an arrow indicates the direction of the applied load. If the arrow is pointing in
the wrong direction, change the position of the load cell so that it is mounted in the direction of the
applied load.
 Check for binding on the Load Cell or other parts of the weighing system.
