13.3.4 MERCURE 200 calibration
1. Call up the calibration menu.
2. Press the <MENU> key until C-2 appears on the left-
hand display.
3. Attach a motor vehicle wheel of medium size (e.g.
rim width 5.5", rim diameter 14") and in very good
condition to the flange.
4. Enter the rim data.
5. Close the wheel guard.
 Measurement commences.
 The left-hand display shows C-3, the right-hand
display shows 60.
6. Attach the 60 gr calibrating weight to the rim.
 The new value is displayed on altering the balance
weight.
7. Attach a balance weight of the value entered to the
inner side of the wheel.
8. Close the wheel guard.
 Measurement commences.
 The left-hand display shows C-4.
9. Turn the wheel until the balance weight is in the 12
o'clock position.
10. Remove the balance weight from the inner side
of the wheel and attach it to the outer side (12
o'clock position).
11. Close the wheel guard.
 Measurement commences.
 The left-hand display shows C-5.
12. Turn the wheel until the balance weight is in the 6
o'clock position.
 The calibration angle value is displayed.
13. Press the <SPLIT> key.
" This completes MERCURE 200 calibration.
i The calibration made is permanently stored auto-
matically.

Reference measurement

i Exact centering of the wheel is a basic prerequisite
for this reference measurement and for all balanc-
ing operations.
i Automatic start has been activated in the description
that follows.
1. Attach a motor vehicle wheel of medium size (e. g.
width 5.5", diameter 14") to the flange.
i Use the same sample wheel as in the calibration
phase.
2. Enter rim data.
3. Close the wheel-guard hood.
 Measurement commences.
4. Create an artificial imbalance by attaching a test
weight of 60 g, for instance, to one of the two sides.
5. Close the wheel-guard hood.
 Measurement commences.
 The MERCURE 200 must display precisely this im-
balance (value and position) on this side. For the
other side, the value must not exceed 5 g.
i To check the position of the imbalance, turn the
wheel until the position recommended for attach-
ment of the balance weights is attained. The balance
weight attached must be vertically beneath the axis
of rotation (6 o'clock position).
! Calibration must be repeated in the following cases:
$ Deviation from specified imbalance value (greater
than 1 g on balance weight side, more than 5 g on
other side).
$ Deviation from specified imbalance position (bal-
ance weight not between 5:30 and 6:30 position).
6. Remove balance weight.
7. Release the wheel and rotate it approx. 90°.
8. Secure the wheel again.
9. Close the wheel-guard hood.
 Measurement commences.
" On completion of this reference measurement, the
display must not exceed a maximum imbalance of 10 g
per side (15 g for particularly heavy wheels). This error
may be caused by the rim centering tolerances. If this
reference measurement indicates greater imbalance,
the components used for centering the wheel must
be checked for wear, play and contamination.
