Span Count too Low.
Press CLEAR to continue.
Signal from load cell too low: ensure shipping brackets are removed and proper test weight or chain is
applied during span.
Calibration aborted
Belt speed is too low:
For example: belt speed is <10% of design (P014).
Calibration is out of range Deviation Error:
XX.XX
This indicates 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.
Find and rectify the cause of the increased or decreased deviation. Then re-try a span
recalibration.
If this deviation is still unacceptable, set P388 to 1 to invoke an initial span calibration. Further
deviation limits are now based on this new initial span.
Press the following key:

Initial Span
Note
Perf
orm an initial span when a calibration out of range message appears.
During this step the progress of the process will be shown on the display with a progress
indicator in %.
A zero calibration should be performed prior to performing a span calibration.
