Direct Span

Direct span entry (P368) is intended for use when replacing software or hardware, and
when it is not convenient to perform an initial span. A record of the last valid span count
is required.

Multispan

The BW500 offers a multispan function, which allows the BW500 to be calibrated for up
to eight different feed conditions that would produce varying load characteristics.
Different feed conditions are typically related to the running of different materials or
multiple feed locations. The varying load characteristic often has a bearing on the belt
tension, and is observed especially when in close proximity to the scale. To
accommodate such scale applications, a span correction can be made by selecting and
applying the appropriate span.
Since every material has its own unique physical properties, and may load the belt
differently, a span calibration may be required for each material to realize maximum
accuracy.
In the case of different feeder locations, a span calibration may be required to match
each feedpoint or combination of feedpoints.
