4.3. Cart
4.3.1. Cart Body
A housing for the main encoder and
provides a mounting base for probe holders
and the umbilical housing (Fig. 20).
4.3.2. Cart Handle
The handle is used to both manage cabling
and provide an ergonomic grip during use.
To remove the cart handle, simultaneously
depress the handle release catch and slide
forward (Fig. 21).
4.3.3. Brake Handle
Pivot the brake handle left or right to
engage or disengage the brake.
To remove the brake handle, pull straight
up on the central knob of the black lever.
(Fig. 22). To reinsert, align the spline on the
handle with the socket and press down until
it snaps into place.
NOTE: Pulling the brake handle sideways causes binding and makes the handle
dicult to remove.

4.3.4. Wheels
The wheels of the cart are interchangeable.
To remove/install the cart wheels, insert the
provided 3 mm hex driver (Fig. 14) in the end of the
shaft opposite the
wheel you wish to
remove. Thread or
unthread the
desired wheel by
hand (Fig. 23). Additional magnetic wheels may be installed when added
magnetic attraction is necessary (see Magnetic Wheel Kit on page 24).
TIP: Be sure all wheels are tight as this can aect the brake and encoder
performance.
4.3.5. Umbilical Housing
The umbilical transmits encoder
signals to the user instrument.
To remove the umbilical, first remove
the cart handle (Fig. 21) and brake
handle (Fig. 22). Locate the black wing
knob at the bottom of the cart and
loosen one turn (Fig. 24).
With the knob loose, slide the umbilical
housing towards the rear of the cart
(Fig. 25).
TIP: The umbilical lock knob is only re-
quired to be loose, one turn should
be enough to remove the umbilical.
Fig. 23 - Umbilical housing removal
WARNING! MAGNETIC MATERIAL. The
magnetic wheels produce a magnetic eld which may
cause failure or permanent damage to items such as
watches, memory devices, CRT monitors, medical
devices or other electronics. People with pacemakers or
ICD’s must stay at least 25 cm (10 in) away.

PAGE 9 of 42 BT0179 Rev 04.5
TIP: If the umbilical does not slide freely from the body, you may need to push on the
wing knob to loosen the dovetail nut.
4.3.6. Front Pivot
The front pivot oers an attachment point for various frame bars.
To attach a frame bar, loosen both dovetail jaws enough to allow the frame bar
to be inserted and tighten the knobs (Fig. 26).
The angle of the bar can be adjusted by loosening the side mounted lever,
pivoting to the desired angle, and closing the lever again (Fig. 27).
4.3.7. Rear Pivot
The rear pivot is positioned at the rear of the cart body and provides an
attachment point for various frame bars. To mount a rear pivot follow these
steps:
1. Release the side mounted lever and rotate the pivot down 90° (Fig. 28).
2. Align the rear pivot with the pins at the rear of the cart (Fig. 29).

3. Using the supplied 3 mm hex driver, screw the rear pivot to the cart (Fig. 30).
4. Rotate the pivot to the original position and lock the side mounted lever
(Fig. 31).
4.4. Pivot Buttons
Available in a variety of shapes
and sizes fitting various wedge
dimensions.
Use the supplied 3/8 wrench
(Fig. 15) to remove and install
pivot buttons in the desired hole
location (Fig. 32).
4.5. Frame Bar
Frame bars (Fig. 33) are used to mount
probe holders, probe positioning systems
and other accessories.
Frame bars are available in a variety of
lengths (see - Frame bar on page 10).

To mount a UT wedge in the probe holder, follow these steps:
1. Rotate the probe holder adjustment knob and attach probe holder to a
frame bar (Fig. 35).
2. Use the probe holder adjustment knob to position the probe holder along
the frame bar (Fig. 36).

3. Use swing arm knob to position the swing arm (Fig. 37).
TIP: The swing arm is typically used to adjust TOFD center to center distance
relative to the phased array probes on a four probe configuration (Fig. 33).
4. Using the supplied 3/8 in wrench (Fig. 15), place the pivot buttons as required
(Fig. 38).
TIP: If narrow scanning footprint is required, use pivot button holes closest to the
yoke. Wedge pivoting may be impeded when closer to the yoke.
5. Loosen the arm clamp screw and the probe holder arm adjustment knob
(Fig. 39), remove the outer probe holder arm from yoke.
6. Adjust inner probe holder arm as required to best centre the probe on the
yoke’s pivot axis (Fig. 39).
TIP: The probe holder yoke can accommodate many dierent probe and wedge
sizes of varying widths. It is best to centre the wedge with the yoke’s pivot
axis to reduce wedge tipping when scanning. Position the inner probe holder
arm accordingly with the centre of the yoke (Fig. 33).
7. Position the wedge on the inner
probe holder arm (Fig. 40).
8. Tighten the arm clamp screw
(Fig. 40).
9. Slide outer probe holder arm along
the yoke pinching the wedge in
place.
10. Tighten probe holder arm
adjustment knob (Fig. 41).

4.6.2. Probe Holder Adjustment
To adjust the probe holder, follow these steps:
1. Ensure probe holder is in latched, upper position (Fig. 42). If the probe holder
is already latched, it will only move within the slip joint adjustment range and
have no spring tension.
2. Push the probe holder yoke down toward inspection surface until the
wedge is approximately 6 mm (¼ in) above the inspection surface (Fig. 43).
3. Lift probe slightly and press latch button (Fig. 44) to apply spring pressure to
the wedge.
4. Gently lower probe holder and wedge to the scanning surface (Fig. 45).
4.6.3. Probe Holder Force Adjustment
It is possible to adjust the tension of the probe holder spring.
NOTE: To perform this operation the 2 mm hex wrench (Fig. 17) and 3 mm hex
wrench (Fig. 19) is required.
Light 1 kg 2 lb
Medium 2 kg 4 lb
Heavy 3 kg 6 lb
When configured correctly, these
settings exert the indicated spring
force on the Probe.

Fig. 44 - Lift and press latch button Fig. 45 - Spring loaded scan position

PAGE 14 of 42
To adjust the probe holder’s force, follow these steps:
NOTE: Do not perform this operation on scanning surface.
1. Ensure the probe holder is in the upright latched position (Fig. 42).
2. Lift probe holder slightly and press the latch button (Fig. 46) to release the
probe holder the full 45° degrees.
3. Insert the short arm of a 3 mm hex wrench into the 3 mm slot (Fig. 47).
4. Place the 2 mm hex wrench into the force adjustment screw (Fig. 48).
5. Lightly press the long arm of the 3 mm hex wrench down. Using the 2 mm
hex wrench, loosen the force adjustment screw but do not remove it (Fig. 49).
6. Gently apply pressure on
the long leg of the 3 mm
hex wrench until the force
adjustment marker lines
up with the desired spring
tension. While keeping the
markers in line, tighten the
force adjustment screw
(Fig. 50).

4.6.4. Slip Joint Probe Holder Left/Right Conversion
To reverse the probe holder, follow these steps:
1. Unscrew the yoke from the swing arm (Fig. 51).
2. Loosen the probe holder arm adjustment knob and arm clamp screw. Slide
the arms from the yoke (Fig. 52).
3. Flip the yoke 180° and reverse the probe holder arms (Fig. 53).
4. Place the pivot buttons on the inside of the probe holder arms (Fig. 54) using
a 3/8 in wrench (Fig. 15). Slide the arms onto the yoke and tighten the probe
holder arm adjustment knob and the arm clamp screw.
