- Preset the nominal width, which is normally stamped on the
rim, or else measure the width "b" with the calliper gauge
(standard accessory).
- Press button to switch to manual setting of all wheel dimensions.
- Press button to return to the Measurement screen.
"AUTOMATIC WIDTH" OPTION
- Move the gauges simultaneously into measuring position.
For distance + diameter gauge, see fig. 8.
Fig. 8B WIDTH gauge
During gauge movement, the symbols appear in movement on the display (see fig.8C/8D) indicating that
the gauges are not steady.
- Hold the gauges still in position for approx. 2 sec.
- Successful memorization is given by the change in colour of the correction weights which passes from
blue to red.
- Return the gauges to rest position.
N.B. - If the symbols of fig. 8C/8D remain on the display, it means that relative measuring gauge is not in
rest position.
- The two measurements (distance + diameter and width) can be made at different moments. In this
case first make the (distance + diameter) measurement. Correct position of the gauge tips is
essential for accurate measurement. Incorrect measurement of the distance entails incorrect width
measurement. Check that the data calculated with the nominal width stamped on the rim (errors up
to 1/2" do not normally cause appreciable residues).
