- Keep the arm in position and wait for the acoustic confirmation signal.
- Return the measuring arm to the rest position.
If the measuring arm is returned to the rest position after acquiring the data relating to
only one plane or if first the outer plane data then the inner plate data are acquired, the
"A 23" message is displayed and the acquired data are not considered.
- Carry out a spin
in the version with manual sensor, proceed as follows:
- Press the key to prepare the machine for entering distance d1 relative to the
internal side (the distance LED lights up on the panel).
- Position the end of the measuring arm on the plane chosen for the application of the
inner weight (Fig. 13/13a for ALU 1P and Fig. 10/10a for ALU 2P). In Alu 1 P, the centre of
the pawl on the end section of the lever is taken as a reference for the centre line of the
weight (version without the weight holding device). In versions with the weight holding
device, the centre line of the weight must correspond with the centre of the groove in
which the weight will be placed. In Alu 2 P, the rim edge is taken as a reference, since
the inner weight is of the conventional clip type.
Pay maximum attention when the end of the arm is being positioned in an area of
the rim free of discontinuity, so that the weight can be applied in that position.
- Read the internal distance d1 from the body on the rule.
- Modify the value on the right display by pressing the
previously measured distance d1.
- Press the key again to prepare the machine for entry of the d2 distance relating
to the outer side (the distance LED lights up on the panel).
- Position the end of the measuring arm on the plane chosen for the application of the
outer weight, as previously described for the inner side.
- Read the distance d2 from the body on the rule.
- Modify the value on the right display by pressing the
previously measured distance d2.
- Press the key again to set the machine for entering the nominal wheel diameter.
- Read the rated rim diameter value on the tyre.
- Modify the value displayed on the right display by pressing the
get the previously measured nominal diameter.
