Example of a smooth run-down diagram (segment size ~26 cm)

Figure 9-5 shows an example of a smooth run-down test over a large
distance. Because of the large segment size, the drum unbalance is no
longer directly visible. The unbalance however is indirectly visible,
because it causes the lines to be wider apart now. The slope in the
measured frequency is caused by the wire weight that increases for
lower levels.

Example of an erroneous run-down diagram

Figure 9-6 shows an example of an erroneous run-down test over a
small distance. The gauge clearly shows issues over the complete
range, indicating that this couFigure 9-6ld be bearing issues rather than
obstructions.
