4.4 Symmetry measuring (Cross-measuring)
Before starting to measure it is important to
check the setting of the measuring arm, see
4.3 LENGTH MEASURING.
Measuring symmetry of a vehicle according to
dimension data sheet does not differ to any
significant extent from the previous section, 4.3
LENGTH MEASURING.
Symmetry measuring uses basically the same
procedure.
It is important during symmetry measuring
to NEVER measure or check height
deviations at the same time. The reason for
this is that the height measurement value
can be affected by the lateral inclination of
the vehicle. It is, however, important that the
height measuring rod be adjusted to the
same height applicable to length measuring.
In all other aspects, the same procedure as in
length measuring applies.
1. Read the height dimension given on the
data sheet and select a suitable height
rod. Mount the height rod in the
measuring head.
2. Mount a suitable socket/tip at the top of
the height rod or the next even numbered
socket if the datasheet shows a socket
with uneven number.
3. Read the given symmetry dimension on
the data sheet (measuring line no 2),
which makes the length between the
magnet attachment and the measuring
point to measure.
4. Mount the magnetic attachment on the
chosen magnet point on the vehicle. Pull
out and adjust the measuring arm so that
the selected measurement point can be
reached.
It can be advantageous here to use the
hold feature to freeze the measurement
value, especially if it is difficult to see the
display while measuring. Press the
