Before the measuring is started the spring packages at the inside of the two-mass-flywheel have to be
positioned. Therefore the flywheel has to be turned not more than three times into the desired
direction with a torque of about 350 Nm. After this the angle measuring system has to be reset to
null.
Thereafter the measuring can be done according to the following table. The measured angle values
have to be within the minimum and maximum tolerance values. The measuring direction may not be
changed during the procedure unless the spring packages will be repositioned for the change of the
direction.
