Set Wheel Circumference
cm
The wheel size used by the instrument to
calculate distance can be adjusted to match
your front tire circumference. Place a mark on
your tire and a corresponding mark on the floor.
Roll the wheel one revolution, then place a
second mark on the floor. This is your actual
wheel size. For our example we will adjust the
instrument to a wheel size of 215 cm.
