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. From the run mode initiate zero calibration current zero count = #### 1 2 zero calculation, load value displayed 1 2 zero deviation calculated 1 2 accept deviation new zero count = #### 1 2 return to run mode 1 2 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. 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. Recalibration Page 32 Milltronics BW100 - INSTRUCTION MANUAL 7ML19985DJ01
