Figure 2-20 Separating the two halves of the scanner
4. For dual-probe scanning, you need to assemble the two halves of the scanner (see
Figure 2-21 on page 38):
a) For outside diameters less than 32.5 mm (1.280 in.), use only one crossbar.
Slide the crossbar through the link of each probe holder, and then clamp the
crossbar in the desired position with the crossbar screw.
b) For outside diameters greater than 32.5 mm (1.280 in.), use two crossbars:
(1) Slide one crossbar through the link of each probe holder, and then clamp
the cross bar in the desired position with the crossbar screws.
(2) Slide the second crossbar through the male links that are roughly in the
center of the scanner, and then clamp the crossbar in place with the
crossbar screws.
(3) Use the graduations on the crossbars to set the scanner separation equal
at both crossbar locations. You can set the exact probe spacing later (see
section “Using the Wedge-Separation Indicators” on page 41 for details).
