Attention!
Measuring the actual perimeter of the
wheel: To measure the actual perimeter
of your wheel, make a dot on the In-Line
Skate Speedometer Wheel. Then roll your
skate over a piece of paper and mark the
places when the dot is closest to the
paper at least two times, the distance
between the two marks is the required
perimeter in [mm].
Programming the Display:
1. Setting the perimeter of the wheel:
To start the programming mode of the
display press
MODE
followed by the
SET
-
button. On the display the
PM
(perimeter)
symbol appears.
The preset perimeter is 239 mm, which
is equivalent to a 76 mm diameter wheel.
The range for the allowed perimeters
varies from 210 to 251. Press
DOWN
until
the correct value is reached, i.e. 251 for
an 80 mm wheel.
If “rockering“ is not possible with your
skates please use the next larger size of
the In-Line Skate Speedometer Wheel. The
exposure of this wheel will soon be worn
out by the higher pressure on this wheel.
The bigger size of the wheel does not
effect the accuracy of the measurement.
Pay attention that you always program the
perimeter of the In-Line Skate Speedo-
meter Wheel in the display and not the
perimeter of your other wheels.
Adjusting the wear out function:
The built in wear out function is based
on the statistical normal use of skates.
The real perimeter reduction may differ
individually due to the conditions of the
ground usually skated on as well as the
weight and technique of the skater. If you
get the feeling that the displayed perime-
ter differs from the real perimeter, you
should reprogram the watch with the
actual value to guarantee the precision
of the measurement.
