HST-Lite Scanner 9
1. HST-Lite Scanner
The HST-Lite Scanner is a versatile pipe and plate scanner, which can be used to
inspect welds using TOFD and pulse-echo techniques.
The HST-Lite Scanner is composed of the following items (see Figure 1-1 on page 9):

1.1 Positioning the Frame Bar
The frame bar must be positioned differently according to the wedge model used:
• Stainless steel wedges (IHS)
• Rexolite wedges (IHC)
The engraving corresponding to the wedge model used must be facing upward. If it is
not the case, perform the following procedure.
To position the frame bar
1. Loosen the wheel block, the probe holder, the handle, and the wheel encoder
thumbscrews, and then remove all the components from the frame bar (see
Figure 1-2 on page 10).
Figure 1-2 Disassembled scanner
2. Position the frame bar so the engraving corresponding to the wedge model used
(IHS TOFD WEDGES or IHC TOFD WEDGES) is facing upward (see Figure 1-3 on
page 11).

3. Reassemble the scanner.
1.2 Installing a Probe and a Wedge in a Probe Holder
To install a probe and a wedge in a probe holder
Before installing a new probe into a probe holder, make sure that there is enough
couplant between the probe face and the wedge.
1. Apply couplant on the probe face (see Figure 1-4 on page 12).

2. Install the probe on the wedge.
3. Loosen the yoke thumbscrew (see Figure 1-5 on page 12).

4. Install the probe and wedge assembly between the two yoke arms (see Figure 1-6
on page 13).
Figure 1-6 Wedge installed
5. Push the yoke arm in order to place the yoke arm guiding pin into the wedge side
hole (see Figure 1-6 on page 13).
6. Tighten the thumbscrew until it holds the yoke arm tight against the holder.
7. Repeat the procedure to install the other wedge.
1.3 Setting the Distance Between Beam Exit Points
To set the distance between beam exit points
1. According to the scan plan, determine the distance between the beam exit points
(for example, 40 mm).
2. Divide the distance value by two (for example, 20 mm).
3. Position the probe holders so their indicators point to the half value (for example,
20 mm) on the left- and right-hand side frame rulers (see Figure 1-7 on page 14
and Figure 1-8 on page 15).

A millimeter appears as the distance between two short lines. The distance between
two long lines is 5 mm.
4. To make sure that the distance between beam exit points is properly set:
When using Rexolite wedges, measure the distance between the dots
engraved on yoke arms (see Figure 1-8 on page 15).
OR
When using stainless steel wedges, measure the distance between the vertical
lines engraved on wedges (see Figure 1-9 on page 15).

1.4 Positioning the Wheel Encoder
To position the wheel encoder
1. Loosen the wheel encoder thumbscrew (see Figure 1-10 on page 16).
2. Slide the wheel encoder to the desired position (see Figure 1-10 on page 16).
3. Tighten the wheel encoder thumbscrew.
Figure 1-10 Positioning the wheel encoder
1.5 Installing Tubing and Cables
To install tubing and cables
1. If you plan to use the offset probe configuration, assemble the HST-Lite Scanner
according to section 1.9 on page 26.
2. If required, install the preamplifier (see section 1.8 on page 24).
3. Connect the probe cables to the probes.
4. Cut four pieces of transparent tube. They should measure about 3.8 cm (1.5 in.)
long.
5. Install the four transparent tubes on the wedges (see Figure 1-11 on page 17).
6. Install a Y-fitting on each pair of transparent tubes (see Figure 1-11 on page 17).
