48 9.6 Measuring Unbalance; 49 9.7 Application Of The Balancing Weights - WERTHER INTERNATIONAL MERCURE 200 Manual De Instrucciones

Fig. 53:
3. Lock the detected measurement by tightening the
thumbscrew (7) and detect the value in position "J"
on the millimetric scale;
4. After pressing the "Width" key
to enter the rim width value measured in "inches".
" All the required wheel data have been recorded.
9.6 Measuring unbalance
i A wheel can only be correctly balanced if all the set-
tings correspond to the mounted wheel.
i The automatic start is activated. In the following
description.
i Measurement can be interrupted at any time by
pressing <STOP>.
1. Close the wheel guard.
 The imbalance measurement starts automatical-
ly, if set to start automatically, otherwise press
<START>;
2. On completion of measurement the values of the bal-
ance weights required are shown on the display.
$ left display for internal balancing plane;
$ right display for external balancing plane.
3. Open the wheel protection cap only when the wheel
has completely stopped.
i If the imbalance measured on the wheel is very high
(e. g. static unbalance exceeding 50 g) it is recom-
mended to perform optimisation procedure through
which the static imbalance of the tyre is balanced
with the static imbalance of the rim (minimisation of
the imbalance, see chap.10).

i After you have secured the balancing weights, repeat
the unbalance measurement for checking purposes.
9.7.1
i LEDs in arrow form (Fig. 36, pos.7) indicate the di-
rection in which the wheel has to be turned in order
to reach the 12 o'clock position for securing the
balancing weight.
i In the following description the audio is activated.
Internal weight fixing:
1. Turn the wheel by hand.
 The LED (Fig. 36, pos.8) lights-up as soon as the
, use <-> or <+>
correct position for fixing the balancing weight is
reached and an acoustic signal sounds to confirm
the correct position.
i Block the wheel with the pedal.
2. Fasten the balancing weight of the value indicated
on the left display in the highest perpendicular posi-
tion (12 o'clock) of the wheel if it is a clamp weight,
otherwise use the weight positioning calliper for an
adhesive weight.
i The internal weight can be either a spring-clip weight
of an adhesive weight according to the selected
balancing program.
¶
See chap.9.8 to fix the spring-clip weights.
¶
See chap. 9.9.2 to fix the adhesive weights with
internal clamp.
External weight fixing:
1. Turn the wheel by hand.
 The LED (Fig. 36, pos.2) lights-up as soon as the
correct position for fixing the balancing weight is
reached and an acoustic signal sounds to confirm
the correct position.
i Block the wheel with the pedal.
2. Fasten the balancing weight of the value indicated on
the right display in the highest perpendicular posi-
tion (12 o'clock) of the wheel if it is a clamp weight,
otherwise use the weight positioning calliper for an
adhesive weight.
