OPERATION
7.1. Setup of CIRC-IT on a Pipe or Tube
1. Install the wedges (see Installing Wedges on page 20) as well as set the desired
probe spacing (see Setting Wedge Spacing on page 28) (Fig. 32).
2. Determine the diameter of the pipe or tube to be
scanned. Included in the CIRC-IT kit is a setup
chart which will indicate the number of links,
wheel links and type of latch required
based on the pipe/tube diameter
(Fig. 33).
3. Assemble the
appropriate configuration of
links, wheel links and latches (see
Link Connection on page 41) to the
scanner body (Fig. 34).
TIP: This example provided is a
configuration for a 3.5 inch
tube diameter.
Fig. 32 - Set wedge spacing
Fig. 33 - Refer to setup chart
Fig. 34 - Assemble links on a flat surface

PAGE 15 of 53 DJ0050 Rev 05.4
NOTE: Alternate wheel links and links ensuring links are always separated by a wheel
link (see Correct Link Configuration on page 42).
4. Loosen the two screws (Fig. 28-H) on either side of the setup tab (Fig. 28-F), do not
remove these screws, a 1/4th turn should be sucient. Perform this task on both
sides of the scanner (Fig. 35).
5. Lower the setup tab on both sides of the scanner (Fig. 36).
6. Tighten the screws of the setup tabs (Fig. 37).
