Allvis – Manual (EN 2021-05-25)
4 Measuring
The technician must have a clear understanding of the
damage to the vehicle before attempting to use the Allvis
measuring system and vehicle dimension data.
Being well informed and aware of specific structural damage
to the vehicle beforehand will highlight possible faults or
inconsistencies in measurement values on data sheets at an
early stage, also incorrect mounting, calibration or measuring
points selected by mistake.
Measurement values shown on data sheets and the way the
measuring arm is being used should be constantly reviewed
to ensure that it is being used correctly. Likewise checking to
see that the right vehicle has been selected in the database is
equally important.
When in doubt check the above points thoroughly, and if the
problem persists, contact the ALLVIS distributor or submit your
question to our on-line tech support. Refer also to items 3.1 –
3.2.
4.1 Mounting the Magnet Attachment
Make sure that the mounting points on both sides of the
vehicle are in the right location, and that they have been
cleaned.
Select a suitable height calibration rod and snap the magnetic
adaptor onto the ball of the height rod and test attach it in the
selected mounting position. Make sure that the magnetic
attachment is firmly seated and that there is no play.
Remove the magnetic attachment with height calibration rod
and mount it in the socket at the rear end of the measuring
arm. Use firm downward pressure to click the rod in place.
