OPERATION
3.1. Microbe Setup on a Scanning Surface
1. Assemble the appropriate
conguration to the cart (Fig. 11).
Install the wedge and probes that
will be used (see Slip Joint Probe
Holder on page 11).
2. Route cables and hoses through
the cart handle as a means of cable
management (Fig. 12)
3. Ensure cart’s brake is locked (see
Brake Handle on page 7).
4. Place the congured MICROBE on
the scan surface (Fig. 13).
TIP: Use caution when placing
equipment on the scan
surface. The magnetized
wheels can cause the
assembly to jump towards
the inspection surface.

5. Adjust the pivot nose (Fig. 14) angle to align the frame bar parallel with the
tangent of the scan surface (Fig. 15).
6. Lower the probes to the scan surface (see Probe Holder Adjustment on page 13)
to begin scan process (Fig. 16).

COMPONENT OVERVIEW
4.1. Cart
4.1.1. Cart Body
A housing for the main encoder and
provides a mounting base for probe holders
and the umbilical housing (Fig. 17).
4.1.2. 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. 18).
4.1.3. 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. 19). 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
difcult to remove.

4.1.4. Wheels
The wheels of the cart are interchangeable.
To remove/install the cart wheels, insert the provided
3 mm hex driver (Fig. 1) in the end of the shaft
opposite the wheel
you wish to
remove. Thread or
unthread the
desired wheel by
hand (Fig. 20). 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 affect the brake and encoder
performance.
4.1.5. Umbilical Housing
The umbilical transmits encoder
signals to the user instrument.
To remove the umbilical, rst remove
the cart handle (Fig. 18) and brake
handle (Fig. 19). Locate the black wing
knob at the bottom of the cart and
loosen one turn (Fig. 21).
With the knob loose, slide the umbilical
housing towards the rear of the cart
(Fig. 22).
TIP: The umbilical lock knob is only
required to be loose, one turn
should be enough to remove the
umbilical.
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.
Fig. 20 - Umbilical housing removal
WARNING! MAGNETIC MATERIAL. The
stabilizer wheel uses a magnetic wheel. People with
pacemakers or ICD’s must stay at least 25 cm (10 in)
away.

4.1.6. Frame Bar
Frame bars (Fig. 23) are used to
mount probe holders, probe position-
ing systems and other accessories.
Frame bars are available in a
variety of lengths (see Frame Bars on
page 34).
4.1.7. Front Pivot
The front pivot offers 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. 24).
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. 25).
4.1.8. Rear Pivot
The rear pivot is positioned at the rear of the cart body and provides an attach-
ment 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. 26).
2. Align the rear pivot with the pins at the rear of the cart (Fig. 27).
3. Using the supplied 3 mm hex driver, screw the rear pivot to the cart
(Fig. 28).
4. Rotate the pivot to the original position and lock the side mounted lever
(Fig. 29).
4.1.9. Pivot Buttons
Available in a variety of
shapes and sizes tting
various wedge dimensions.
Use the supplied 3/8
wrench (Fig. 2) to remove
and install pivot buttons in
the desired hole location
(Fig. 30).

3. Use swing arm knob to position the swing arm (Fig. 34).
TIP: The swing arm is typically used to adjust TOFD center to center distance
relative to the phased array probes on a four probe conguration (Fig. 10).
4. Using the supplied 3/8 in wrench (Fig. 2), place the pivot buttons as
required (Fig. 35).
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 probe holder arm adjustment knob (Fig. 36) and remove 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. 36).
TIP: The probe holder yoke can accommodate many different 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. 36).
7. Position the wedge on the inner
probe holder arm (Fig. 37).
8. Slide outer probe holder arm
along the yoke pinching the
wedge in place.
9. Tighten probe holder arm
adjustment knob (Fig. 38).

4.2.2. Probe Holder Adjustment
To adjust the probe holder, follow these steps:
1. Ensure probe holder is in latched, upper position (Fig. 39). 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. 40).
3. Lift probe slightly and press latch button (Fig. 41) to apply spring pressure
to the wedge.
4. Gently lower probe holder and wedge to the scanning surface (Fig. 42).
4.2.3. 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. 4) and 3 mm hex wrench (Fig. 6) is required.
Light 1 kg 2 lb
Medium 2 kg 4 lb
Heavy 3 kg 6 lb
When congured correctly, these
settings exert the indicated spring
force on the Probe.

6mm approx.
Fig. 41 - Lift and press latch button Fig. 42 - Spring loaded scan position

PAGE 14 of 36
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. 39).
2. Lift probe holder slightly and press the latch button (Fig. 43) 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. 44).
4. Place the 2 mm hex wrench into the force adjustment screw (Fig. 45).
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. 46).
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. 47).

4.2.4. Slip Joint Probe Holder Left/Right Conversion
To reverse the probe holder, follow these steps:
1. Unscrew the yoke from the swing arm (Fig. 48).
2. Loosen the probe holder arm adjustment knob and arm clamp screw.
Slide the arms from the yoke (Fig. 49).
3. Flip the yoke 180° and reverse the probe holder arms (Fig. 50).
4. Place the pivot buttons on the inside of the probe holder arms (Fig. 51)
using a 3/8 in wrench (Fig. 2). Slide the arms onto the yoke and tighten the
probe holder arm adjustment knob and the arm clamp screw.
