i
When calibrating the rim data, the handle of the
electronic rim-distance gauge must be held correctly
to avoid errors when balancing.

12.3.4 Calibration of ROLL R6 M
i
Follow the instructions shown on the monitor.
1. Attach a motor vehicle wheel of medium size
(e.g. width 5.5", diameter 14") and in very good
condition to the flange.
2. Select ROLL R6 M calibration and confirm with <I>.
« Calibration is started.
3. Enter the rim data and confirm with <I>.
4. Press <I>.
« Measurement commences.
5. Enter any balance weight between 40 g and 120 g
and confirm with <I>.
6. Attach a balance weight of the value entered to the
inner side of the wheel.
7. Press <I>.
« Measurement commences.
8. Turn the wheel until the balance weight is in the
12 o'clock position.
9. Remove the balance weight from the inner side
of the wheel and attach it to the outer side
(12 o'clock).
10. Press <I>.
« Measurement commences.

11. Turn the wheel such that the weight is in the 6
o'clock position.
12. Press <I>.
"
This completes calibration.
i
The calibration made is permanently stored
automatically.
12.3.5 Reference measurement
i
Exact centering of the wheel is a basic prerequisite
for this reference measurement and for all
balancing operations.
i
In the following description the audio is activated.
1. Attach a motor vehicle wheel of medium size (e. g.
width 5.5", diameter 14") and in very good condition
to the flange.
i
Use the same sample wheel as in the calibration
phase.
2. Enter the wheel data.
3. Close the wheel guard.
« Measurement commences.
4. Check that the wheel is perfectly balanced, with the
exact measurement value not rounded-off.
5. Create an artificial unbalance by attaching a test
weight of e. g. 60 g to one of the two sides.
6. Close the wheel guard.
« Measurement commences.
« ROLL R6 M must exactly indicate the unbalanced
value applied with a maximum range of error of
5 g.
i
To check the position of the unbalance, turn
the wheel until the position recommended for
attachment of the balance weights is attained. The
test weight attached must be vertically beneath the
axis of rotation (6 o'clock position).
!
Calibration must be repeated in the following cases:
$
The unbalance error applied is greater than 5 g.
$
Deviation from specified unbalance position (test
weight not between 5:30 and 6:30 position).
