Recalibration
Routine Zero
Run the conveyor empty for several minutes to warm up the belt and insure that it is
empty. Test weights are not used during a zero calibration.
The cause of the increased deviation must be found and rectified. A zero recalibration as
previously described can then be retried.
If the operator deems this deviation to be acceptable, set P377 to 1 to invoke an initial
zero calibration. Further deviation limits are now based on this new initial zero.
Note: E3 is an indication that the mechanical system is errant. The use of P377,
initial zero , should be used judiciously and only after a thorough mechanical
investigation has been exercised.
