Affix the probe holders (with attached wedges) to the low profile probe
holder frame. On the frame bar, place the secondary probe holders at the
front
(Fig. 163-2)
and the primary probe holders at the rear
(Fig. 163-1)
.
TIP
: Due to their larger size, scan results are generally improved when pulling or
dragging phased array wedges.
3.
Mount the low profile probe holder frame to the crawler
(see Cable Retainer on
page 48 for additional details)
. When mounting the low profile frame, ensure
the attachment knobs
(Fig. 163)
are at the front (non crawler side).
4.
Release the two swivel mount levers
(Fig. 164)
to position the swivel mount
parallel to the scan surface
(Fig. 165)
. When alignment with scan surface is
achieved, lock the crawler swivel mount levers.
