Accepting the Span returns to start of Span. A new Span can be performed, or enter
Run mode. If calibrating with a test weight or test chain, remove it from the scale and
store in a secure place before returning to the run mode.
Run Mode
Proper programming and successful zero and span calibration allow entry into the
run mode. Otherwise, entry is denied and the first missing item of programming or
calibration is displayed

The initial programming is complete and the BW500 is operating in the Run mode.
The belt conveyor can be put into normal service. The BW500 is functioning under its
initial program and calibration, reporting rate of material flow and totalizing.
If the initial entry and operation in the run mode is successful, the weighing system
should undergo a recalibration by performing a series of material tests. Material tests
will verify the BW500 reporting accuracy, and where inaccuracies exist, allow the
system to be corrected through a manual span adjustment (P019).
Recalibration of the zero and span are ongoing requirements that must be performed
routinely in order to maintain accurate reporting of rate and total.
Refer now to the Recalibration.
e.g. if there is no material on the
belt and the conveyor is running.
The current rate is 0 and no
material has been totalized.
the deviation from the previous span.
For an initial span, there is no previous
span count; hence the deviation is 0.
for example, the new span count, if
accepted
for example, the current span count
