The positioning of the vehicle is in
certain cases decisive for the
measurement accuracy with the
TECH-D measurement tool.
Above all it is the vehicle’s lateral
inclination, which is important, since
this influences the measurement
result when measuring the height of
the vehicle.
The table below reports the influence
on the measurement accuracy in
millimetres and degrees for a specific
lateral inclination of the vehicle.
This illustration shows that the vehicle
is 1200 mm wide, 600 mm on each side
of the centre line, and standing at an
inclination of 2°. If one goes out to 600
mm on the scale and down to 2 on the
graduated scale this shows that the
height difference is 21 mm from the
centre line + or - depending on which
side is measured. The millimetre scale
shows the height difference to be 100
mm from the centre, depending on how
many degrees the vehicle is inclined.
The example shows how important it is
for the vehicle to be level in order to
obtain a correct measurement result.
The table below shows how much must
be added on or taken away to obtain a
correct measurement value.
