The steering function allows measuring the characteristic steering angles:  caster, SAI, TOOT. 

It consists of making several measurements with the wheels steered at different steering angles.

You can select from three steering modes:

• 

FAST steering: recommended because it is fast to execute

•  10° steering: there is no technical reasons to use this method but it is available because many operators 

are accostumed to use it. It is advisable to execute fast steering instead as it is faster 

•  20° steering: necessary to measure the TOOT and when imposed by the vehicle manufacturer

Press the key corresponding to the desired steering mode.
