Recalibration
Routine Span
To perform a routine span recalibration, run the conveyor until the belt is empty and stop
it. Suspend the test weights from the belt scale per its instruction manual.
Run the conveyor empty at maximum operating speed.
The cause of the increased deviation must be found and rectified. A span recalibration as
previously described can then be retried.
If the operator deems this deviation to be acceptable, set P388 to 1 to invoke an initial
span calibration. Further deviations are now based on this new initial span.
Notes:
• E6 is a reminder that a zero calibration is strongly suggested before a span
calibration is initiated. Press ENTER to bypass this message.
• E4 is an indication that the mechanical system is errant. The use of P388, initial
span, should be used judiciously and only after a thorough mechanical
investigation has been exercised.
Note: Remove the test weight when the span calibration is complete.
