NOTE :
If zero ( no unbalance) is displayed on display „1” there will be not loacation display on display
„2” . The same applies to displays „3” and „4” .
It may happen that in subsequent measurement of wheel unbalance at cut - off threshold set at
e.g. 5g, the results will be as follows :
- first measurement : 0
- second measurement : 5g
- third measurement : 0
- etc..
These results are not no errors. The unbalance value is for sure close to the nominal value of 5g
cut - off threshold set and therefore 0 or 5 appear alternatively. For 10g threshold the results
may be 0 or 10.

Balancing light - alloy wheels
Light - alloy wheels are balanced by means of stick - on weights or combination of stick - on
and studded weights. Set appopriate balancing programme according to the method of fixing
weights (see item 8.3.4) .
NOTE :
Measurement settings are entered as for studded weights. these are geometrical dimensions
of the whell rim. Selection of appoprite balancing method ( e.g. both weights stick- on) results
in the balancing machine taking into account the change in weight fixing points - on respective
correction planes different from those resulting from the entered data.
Stick - on weights must not be removed and replaced. Therefore after unblance value has
been displayed stuck always a weight 5 -10 g lighter than that indicated by the machine. After
second measurement this unbalance may be corrected by sticking another small weight (e.g.
5 g ) at the new balance point as indicated by the machine. In such way possible position
correction by shifting the weights is avoided which in the case of stick -on weights is not possible.
9.6. Conversion of unbalance
Push - button marked
is used for unbalance conversion.
Example :
Data, inccorect for the wheel balanced were entered in the machine memory . The measurement
was carried out but the results were incorrect. If we want to know the true unbalance values for
this wheel without another measurement, enough to enter in the machine memory ( see item
8.3.2 - 8.3.4.) correct data and push - button
