1.0 Mach-I Introduction
The Mach-I is a portable, compact, lightweight and user friendly Digital Ultrasonic Flaw Detector. The
Mach-I has a COLOR LCD display which provides a wide viewing angle and allows for fast scanning
speeds. The Mach-I’s fully charged battery gives continuous operation of eight hours and charging
time is just 2 to 3 hours. A-scan trace pattern can be directly printed out on a conventional PC printer
having serial port interface or can be transferred to a PC via RS232 Serial port for storage of data.

2.0 Ultrasonic Flaw Detector Basics
The Mach-I is a single channel ultrasonic testing instrument used for the inspection of homogeneous
materials for the presence of inclusions, porosity and other discontinuities that can affect the
performance of material and components. It can also be used for thickness gauging of homogeneous
materials, requiring access from only one side of the test piece. High frequency sound (ultrasonic
sound) waves are introduced into the test material or part from a transducer/probe that is usually
coupled to the test piece by water or other suitable coupling liquid. The transducer converts electric
signals to ultrasound and vice versa. A short burst of ultrasound is introduced into test material so
some or all of the energy is reflected by discontinuities. The reflection of the ultrasound
energy is a function of the ratio between the
acoustic impedance of the discontinuity and the
base material. The greater the impedance ratio
the more sound energy will be reflected. The
principle of ultrasonic testing is shown in figure1.
It shows the ultrasonic energy generated in the
test piece and resulting instrument display.
Thickness gauging with the Mach-I
operates on the principle of the time-of-flight

Mach-I OPERATING MANUAL Rev. 2.0 1/12/06 PAGE 5 of 37
measurement. This principle utilizes the precise timing of the transit time of a short burst of ultrasound
energy through a material under test. The ultrasound waves travel to the far side of the test piece and
reflect back to the transducer/probe and a measurement is obtained.
Transducers
Basically three types of transducers/probes are available for different types of applications:
1. Straight beam Probe (Normal probe)
2. TR probe (Dual crystal probe)
3. Angle beam Probe
1. Straight beam Probe: A straight beam probe introduces ultrasound normal to the test piece
surface utilizing longitudinal or compression waves. Straight beam probes are used primarily for
flaw detection and thickness gauging (ref. Figure 1.).
2. Dual probe: A dual probe contains separate transmitting
and receiving elements (as shown in Figure 2)
usually mounted on delay lines. This design
improves near surface resolution by separating
the initial pulse from the received echoes. Dual
probes are suitable for thickness gauging of pitting
and corrosion and are also better for near surface resolution.
Mach-I OPERATING MANUAL Rev. 2.0 1/12/06 PAGE 6 of 37
3. Angle Beam Probe: An angle beam probe introduces ultrasound at an angle to the surface of
the test piece. In most angle beam probes, the
wave energy is mode converted from a
longitudinal wave to a shear wave by the
refraction principle . These probes are suitable
for inspection of welds. The reason
for this is its ability to position the
transducer/probe away from the weld bead
yet propagate energy into the weld zone.
Another reason to use angle beam testing on
welds is to position the sound beam more
normal to the expected discontinuities since
the flaws in welds are usually perpendicular to
the test piece (except porosity). Figure 3 shows the principle of angled beam weld testing.

6.0 Printer Interface
The Mach-I can print a copy of A-Scan patterns with full calibration set-up values. This requires a
conventional PC printer having a Serial Communication connector. The printer should be an IBM-
PC compatible with the serial port – Serial printer EPSON FX/LQ type is recommended.
Printer settings are below:
Baud Rate 9600 Parity bit None
Data Bits 8 Stop Bits 1
To print out trace pattern, follow these steps.
●Connect Serial cable (supplied with Mach-I) between connector (20) of Mach-I and serial
printer.
●Switch ON Serial PC printer.
●Switch ON Mach-I.
●Get the required Trace pattern and freeze using Freeze key (3).
●Using Menu key go to memory menu (6).
●Using ACTION UP/DN key select “PRINT”.
●Press ENTER UP/DN key to initiate printing.
For Interface with PC Using Serial port refer to Help.txt file supplied in Software CD.

7.0 Power Supply
The Mach-I is powered by a Lithium-Ion battery pack (Mach001) which is fitted in Mach-I using
two screws. It electrically connects to Mach-I via two internal terminal contact points. With fully
charged battery pack, Mach-I can operate continuously for eight hours under typical operating
conditions. The battery pack can be charged when inside Mach-I by connecting Battery charger
Mach002 to the connector (19). Alternatively, the battery pack can be charged outside Mach-I
which allows uninterrupted use of Mach-I using multiple battery packs.
Battery Charging
The battery Charger (Mach002) supplied with Mach-I is a special quick-charge charger. The
charging time is 2.5 hours. The Mach002 battery charger is suitable for use with mains supply from
100 to 240 volts AC/50/60 Hz. The LED on charger illuminates to indicate power on. When the
battery voltage is low (discharged condition) the LED glows RED. When the battery is almost
charged, the LED turns to YELLOW. When the battery is fully charged, the LED glows GREEN.
The output voltage from the charger is 16.4 Volts DC. The charging current is constant at 2.0
Amps.

8.0 Precautions
●Avoid shock to the Mach-I and probes.
●Avoid High-Energy electrical static sources (welding equipment) which can cause erratic
operational behavior in sensitive digital equipment.
●Wipe couplant off probes and Mach-I after each use.
●When battery pack is out-of Mach-I, keep battery contacts away from metal objects.
●Never heat the battery pack (Mach001) nor throw into a fire.
