1.3.2. Maintenance
General cleaning of components is important to keep your system working
well. All components that have no wiring or cables are completely waterproof.
Components can be washed with warm water, dish soap and a medium bristle
brush.
Before using the scanner, ensure all connectors are free of water and
moisture.
NOTE: All components with wiring, cables or electrical connections are splash
proof. However, these components are NOT submersible.
NOTE: Never use strong solvents or abrasive materials to clean your scanner
components.

CHAPTER 4
OPERATION
4.1. Setup of Circ-it on a Pipe or Tube
1. Install the wedges (see Installing Wedges on page 15) as well as set the desired
probe spacing (see Setting Wedge Spacing on page 23) (Fig. 18).
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 blocks and type of latch required
based on the pipe/tube diameter
(Fig. 19).
3. Assemble the
appropriate conguration of
links, wheel blocks and latches
(see Link Connection on page 33) to
the scanner body (Fig. 20).
TIP: This example provided is a
conguration for a 3.5 inch
tube diameter.
Fig. 18 - Set wedge spacing
Fig. 19 - Refer to setup chart
Fig. 20 - Assemble links on a at surface

PAGE 10
NOTE: Alternate wheel blocks and links ensuring links are always separated by a
wheel block (see Correct Link Conguration on page 34).
4. Loosen the two screws (Fig. 14-H) on either side of the setup tab (Fig. 14-F), do
not remove these screws, a 1/4th turn should be sufcient. Perform this task on
both sides of the scanner (Fig. 21).
5. Lower the setup tab on both sides of the scanner (Fig. 22).
6. Tighten the screws of the setup tabs (Fig. 23).
Fig. 21 - Loosen the setup tab screws
Fig. 22 - Lower setup tab Fig. 23 - Tighten screws

PAGE 11 DJ0050 Rev 03.1
7. Loosen the pivot adjustment screws (Fig. 14-I) of the scanner 1/8th of a turn
(Fig. 24).
NOTE: It is unnecessary to loosen pivot adjustment screws beyond a 1/8th turn.
Doing so can hinder proper scanner setup.

Fig. 25 - Wrap scanner around pipe/tube Fig. 26 - Pull and fasten latches

PAGE 12
8. Wrap the scanner around the pipe or tube (Fig. 25).
9. Bring the scanner body around the pipe/tube. Pull and fasten latches (see Latch
Connection on page 32) to the latch hooks (Fig. 14-K) of the scanner. (Fig. 26).
Ensure the latch is in the at position prior to scanning.
10. Ensure that all wheels and both indicator points of the setup tab are contacting
the tube/pipe surface (Fig. 27).
11. Tighten the pivot adjustment screws on both sides of the scanner (Fig. 28).
Fig. 27 - Ensure setup tab contacts scan surface
Fig. 28 - Tighten pivot adjustment screws

PAGE 13 DJ0050 Rev 03.1
12. Loosen the screws of the setup tab on both sides of the scanner (Fig. 29).
13. Lift the setup tabs of the scanner and tighten the screws (Fig. 30).
4.1.1. Setup on diameters smaller than 31.75 mm (1.25 in)
Low clearance scanning on diameters smaller than 31.75 mm (1.25 in) may
require removal of the encoder cable guard (Fig. 14-A).
1. Remove the encoder cable from the clips along the side of the scanner
(Fig. 31).
2. Use the supplied 2 mm hex driver (Fig. 4) to remove the screw from the
wheel and encoder cable guard (Fig. 32).

PAGE 14
3. Remove the encoder cable guard (Fig. 33).
4. Replace the screw using
the 2 mm hex driver
(Fig. 34).
5. Place the encoder cable
in the clips along the
side of the scanner
(Fig. 35).
6. When low clearance
scanning is not required.
Replace the encoder ca-
ble guard by reversing
these steps.
NOTE: When scanning without the encoder cable guard, use caution to prevent
pinching/wearing the encoder cable.
4.2. Single Probe Scanner Setup
To use the CIRC-IT in a single probe scanning conguration,
follow these steps:
1. Loosen the crossbar retaining screws (Fig. 36).
Fig. 35 - Small diameter scanning
Fig. 36 - Loosen crossbar retaining screws

PAGE 15 DJ0050 Rev 03.1
2. Separate the two scanner sections (Fig. 37).
4.3. Installing Wedges
1. If present, remove chain assemblies from the scanner.
2. Loosen the pivot adjustment screws (Fig. 38)
