5.9.2 Measuring run
It is good practice to perform a measuring run after
applying the weights.
Having fi nished the measuring run, if the wheel is
balanced correctly, both the numerical indicators
should indicate 0 and an OK should be displayed
(Fig. 5-30).
Warning
If both unbalance values show 0 but there is no OK
reading, dynamic unbalances below the threshold
value (suppression for values lower than 3.5 g) add to
a static unbalance above the threshold value.
To check how much imbalance is left:
• Select the "Fine" key(21,Fig. 5-30).
Note:
The operator should decide if applying
the stated weight is necessary.
