The measurement can be carried out with two different measurement devices. The measuring instrument used must have a graphic black-white display, a current software release and a memory for up to six articulation angles

Propeller shaft inclinometer

gotis://A_41/46/45_03.0

Units with a graphic black-white display have been delivered since the end of 2003. On these units after switching on, a Romess graphics logo appears on the display. The black-white display is larger than the older four line green display.

An updating kit for up to six articulation angles is available for instruments with a graphic black-white display which only have a memory for four articulation angles.

If an older instrument (with four line green display) or an instrument (with graphic display) with a memory for only four articulation angles is used, the articulation angle measurement must be carried out by means of the inclination measurement function, see:

AR41.10-P-0084RT

Drive shaft bend angles that are outside the specified tolerance range can lead to reports of drivetrain vibration and rough response to acceleration

The transmission mounts and the exhaust system must not be under stress during the inclination angle measurement

If necessary relieve the stress on the transmission mounts and/or exhaust system.

The diagonal struts must not be tensioned during the articulation angle measurement

On vehicles with panoramic glass roof with top sliding roof, code 413.

If necessary, relieve the load on the diagonal struts.

The vehicle must be on its wheels for the measurement.

Display all articulation angles, compare the displayed articulation angles with specified values and correct if necessary

Have the articulation angles displayed by pressing the MEMORY button on the measuring instrument.

The electronic measuring instrument calculates the articulation angles internally from the measured absolute angles, no other calculations have to be carried out!
