* When the measurement value is 999 mm or more, the display
shows “OL”.
* If the peripheral speed ring rotates in the opposite direction
during measurement, the distance is also added to the mea-
surement. For example, assuming that a 20 mm ring rotates and
then returns by 1 mm, the measurement value becomes
20 mm + 1 mm = 21 mm.
