29NOTE :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 ate.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 5gcut - off threshold set and therefore 0 or 5 appear alternatively. For 10g threshold the resultsmay be 0 or 10.9.5. Balancing light - alloy wheelsLight - alloy wheels are balanced by means of stick - on weights or combination of stick - onand studded weights. Set appopriate balancing programme according to the method of fixingweights (see item 8.3.4) .NOTE :Measurement settings are entered as for studded weights. these are geometrical dimensionsof the whell rim. Selection of appoprite balancing method ( e.g. both weights stick- on) resultsin the balancing machine taking into account the change in weight fixing points - on respectivecorrection planes different from those resulting from the entered data.Stick - on weights must not be removed and replaced. Therefore after unblance value hasbeen displayed stuck always a weight 5 -10 g lighter than that indicated by the machine. Aftersecond 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 positioncorrection by shifting the weights is avoided which in the case of stick -on weights is not possible.9.6. Conversion of unbalancePush - button marked is used for unbalance conversion.Example :Data, inccorect for the wheel balanced were entered in the machine memory . The measurementwas carried out but the results were incorrect. If we want to know the true unbalance values forthis wheel without another measurement, enough to enter in the machine memory ( see item8.3.2 - 8.3.4.) correct data and push - button |
