With the rotation of the input axis, the counter drives the internal worm, worm gear and gear mechanism to display the rotation rounds on the 4 groups of decimal counting wheels, which are controlled by a division adjusting knob. When the division adjusting knob indicates “A”, the input axis rotates, and the group A counting wheels count. If the adjusting knob is adjusted to B, C and D respectively, the counting wheel group to which the adjusting knob points will display the rotation rounds of the input axis.
