As auto-trigger function is available, it is not necessary to press the "MEASURE"
button again.
After obtaining tension or frequency values, compare at least two additional
data. If multiple measurement results are close to each other, it means that the
measurements are correct.
More vibrations and measurement errors are prone to occur on the belt with too
low tension. If a tension value cannot be obtained, the belt may be too weak to
produce a clear frequency signal. In order to get an accurate tension value, the
belt should be a little tensioned.
Frequencies are stored in the record, otherwise the red LED light
of the meter will always be on.

Measuring results
Compare the results measured in Section 4.3.3 with the data in the table below. If they are
not within the standard range, repeat the measurement in Section 4.3.3.
