5 Quick Guide
5.1 Quick Guide without Data
•
Take care to select a combination of datum and height measuring rods with attachments that
will leave sufficient room to operate the telescoping measuring arm freely under the vehicle.
•
Ensure that both the datum and height measuring rods are locked in place.
•
The points under the vehicle where the magnetic attachment is to be mounted must be
symmetrical and undamaged.
•
To facilitate fast level calibration of the measuring arm it is important to set up the datum
and height measuring rod lengths so that the measuring arm will be near level with the
vehicle to be measured.
•
The measuring arm must be fully collapsed before calibration and measurement can
commence.
•
During all measuring operations, especially during height measuring and calibration
procedures, it is important to hold onto the digital measuring head and not the telescoping
part of the arm, which could affect measuring accuracy.
•
Beforehand check that the adjustment wheel on the end of the red level is exposed and that
the level is in line with the measuring arm. If not turn the level until it “clicks” in place and
the adjustment wheel is accessible.
•
Never simultaneously compare height and symmetry readings. The same applies to cross-
checking measurements.
•
For best results, make sure that the vehicle is set up level and do not lean on any part of the
vehicle during measuring operations.
•
Always refer to the Allvis main instruction manual prior to measuring!
Coordinate Length Measuring – Using Generic Vehicle Dimension Data
(Follow this procedure when Allvis Vehicle Dimension Data is not available)
Allvis measuring system is equipped with ability to triangulate the vehicle’s measuring points. This
ability is especially developed for measuring operations when for example the manufacturer’s or
some other producer’s general measuring data is used to control measure the vehicle. In these
measure data (Datasheet) the length measures are generally given in a length axle, usually outside
the vehicles side. The same goes for the width measures that are given from a center line and out to
the measuring points on the car.
