The symbol

is displayed automatically for static unbalance exceeding 30 grams (1.1 oz). The program allows

rim. It requires two spins with rotation of the tyre on the rim in the second spin.

Press

To display static unbalance, press the

button on the measurement screen (for ALUS static, the inner side

diameter is always considered).
