i After the start, the external laser (if present and
active) will direct a beam at the wheel.
! The external laser must have been calibrated.
15. Attach a balance weight to the outside of the wheel
at the centre of the laser beam and confirm with by
pressing <MENU>.
 The next screen is displayed.
16. Close the wheel guard.
 The measurement will start. Wait until the pro-
cess is completed.
i If there is no external laser, position the balance
weight at the 12-o'clock position on the outside of
the wheel, press the <MENU> key and close the
wheel guard.
17. Turn the wheel until the balance weight is in the
6-o'clock position.
i The process described here is very important for
calibration.
18. Press the <MENU> key.
19. Remove the balance weight.
" Calibration complete.
i The calibration performed will be automatically
saved permanently.
20. Press the <MENU> key.
 The calibration options are presented again.
12.6.5 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, automatic start is
active.
1. Attach a motor vehicle's wheel that is in very good
condition, of intermediate size and on a steel rim
(e.g. width of 5.5", diameter of 14") to the flange.
i Use the same sample wheel previously used in the
calibration phase.
2. Enter the rim data.
3. Close the wheel guard.
 The measurement will start.
4. Attach a balance weight of 60g to the inside in
order to create an artificial imbalance.
5. Close the wheel guard.
 The measurement will start.
 The MT ZERO 6 LCD must show the exact im-
balance value with a maximum inaccuracy of 5g.
i After the measurement, the wheel will automatically
position itself on the first balancing plane at low
speed. The balance weight attached must be
vertically beneath the axis of rotation (6-o'clock
position).
i Some machine versions require the wheel to be
positioned manually according to the instructions
shown on the display.
! The calibration process must be repeated in the
following cases:
$ Error of the intentionally added imbalance
exceeding 5g.
$ Deviation from the position of the specified
imbalance (balance weight not between the 5:30
and 6:30 positions).
6. Remove the balance weight.
7. Release the wheel, and rotate it by approx. 90°.
8. Secure the wheel again.
9. Close the wheel guard.
 The measurement will start.
" After this reference measurement, the imbalance
displayed must not exceed 10 g per side (15 g for
particularly heavy wheels). The error may result
from the rim centering tolerances. If the reference
measurement indicates a greater imbalance, check the
components used for centering the wheel for wear, play
and contamination.
