3.
Use swing arm knob to position the swing arm
(Fig. 56).
TIP:
The swing arm is typically used to adjust TOFD center to center distance
relative to the phased array probes on a four probe configuration
(Fig. 119)
.
4.
Using the supplied 3/8 in wrench
(Fig. 28)
, place the pivot buttons as
required
(Fig. 57)
.
TIP:
If narrow scanning footprint is required, use pivot button holes closest to
the yoke. Wedge pivoting may be impeded when closer to the yoke.
5.
Loosen the probe holder arm adjustment knob
(Fig. 58)
and remove outer
probe holder arm from yoke.
6.
Adjust inner probe holder arm as required to best centre the probe on the
yoke’s pivot axis
(Fig. 58)
.
TIP:
The probe holder yoke can accommodate many different probe and wedge
sizes of varying widths. It is best to centre the wedge with the yoke’s pivot
axis to reduce wedge tipping when scanning. Position the inner probe
holder arm accordingly with the centre of the yoke (Fig. 58).
7.
Position the wedge on the inner
probe holder arm
(Fig. 59)
.
8.
Slide outer probe holder arm
along the yoke pinching the
wedge in place.
