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 .
From the
zero calibration
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.
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.
Remove the test weight when the span calibration is complete.
