USM Vision+ User’s Manual
Preface
Important Notice
The information in this section must be read and understood by all users of
GE Measurement & Control ultrasonic test equipment. Failure to follow these
instructions can lead to errors in measurements or other test results. Decisions based
on erroneous results can, in turn, lead to property damage, personal injury or death.
General Warnings
Proper use of ultrasonic test equipment requires three essential elements:
• Selection of the correct test equipment
• Knowledge of the specific “test application requirements”
• Operator training about welds
This operating manual provides instruction in the basic setup and operation of the
GE equipment. There are, however, additional factors which affect the use of
ultrasonic test equipment. Specific information regarding these additional factors is
beyond the scope of this manual. The operator should refer to textbooks on the
subject of ultrasonic testing for more detailed information.
Operator Training
Operators must receive adequate training before using ultrasonic test equipment.
Operators must be trained in general ultrasonic testing procedures and in the setup
and performance required by a particular test. Operators must understand:
• Sound wave propagation theory
• Effects of the velocity of sound in the test material
• Behavior of the sound wave where two different materials are in contact
• Areas covered by the sound beam
More specific information about operator training, qualification, certification, and
test specifications is available from various technical societies, industry groups, and
government agencies.
USM Vision+ User’s Manual

Preface
Testing Limitations
In ultrasonic testing, information is obtained only from within the limits of the
sound beam. Operators must exercise great caution in making inferences about the
test material outside the limits of the sound beam. For example, when testing large
materials, it may be impossible or impractical to inspect the entire test piece.
When a less-than-complete inspection is to be performed, the operator must be
shown the specific areas to inspect. Inferences about the condition of areas not
inspected, based on data from the evaluated areas, should only be attempted by
personnel fully trained in applicable statistical and probability techniques. In
particular, materials subject to erosion or corrosion, in which conditions can vary
significantly in any given area, should only be evaluated by fully trained and
experienced operators.Sound beams reflect from the first interior surface
encountered. Because of part geometry and overlapped flaws or overlapped
surfaces, thickness gauges may measure the distance to an internal flaw rather than
to the back wall of the material. Operators must take steps to ensure that the entire
thickness of the test material is being examined.
Operators must be familiar with the use of ultrasonic couplants. Testing skills must
be developed so that couplant is used and applied in a consistent manner to
minimize variations in couplant layer thickness and errors in test results. Calibration
and actual testing should be performed under similar coupling conditions, using a
minimum amount of couplant and applying consistent pressure on the transducer.

Chapter 2. Initial Startup and Operation
2.2 Setting up the USM Vision+
The USM Vision+ has a prop-up stand and handle at the rear that locks into place in
different positions.When completely folded out, it becomes a transport handle for
the instrument. You can set up the USM Vision+ at different angles to have the best
possible view of the screen.
Important: Place the USM Vision+ on a stable flat surface. When operating on a
stable flat surface, make sure that the stand is secure, and do not
touch the instrument on its back. Due to the applied force, the prop-up
stand might move and could either snap to the back or the instrument
could drop on the surface. When opening the handle, be sure to grasp
it firmly to avoid unwanted movements.
The device is intended for indoor or outdoor use. Select a suitable location for
installation that guarantees meeting the environmental conditions. The ambient
temperature must be between 0 and +45°C. The relative humidity must not exceed
95%.
Because the USM Vision+ generates heat during operation, ensure that there is
adequate ventilation and enough clearance between the unit and heat-sensitive
objects or equipment.
Avoid direct heat, heat accumulation and overheating by direct sunlight or other
heat sources. Ensure that there is adequate and unhindered circulation of air.
Ensure that no dirt or only dry, nonconducting dirt accumulates on the instrument,
in particular at the connectors.
The following condition must be met for safe operation:
• No iron or steel dust must penetrate into the instrument, in particular at the
connectors. Apply protective caps on any connectors that are not in use.

Chapter 2. Initial Startup and Operation
2.3 Connecting a Probe
A wide range of probes manufactured by GE may be used in combination with the
USM Vision+, provided the suitable connecting cable is available.The connector
sockets for one or more probes are located on the top side of the USM Vision+.
When connecting probes having only one transducer element, you can use either
connector socket. The connectors for transmitter and receiver are marked with a red
ring (= receiver) and a black ring (= transmitter).
2.4 Power Supply
the USM Vision+ can be powered using an external power supply or by up to two
lithium-ion batteries. You can connect the USM Vision+ to the mains supply system
when the battery is in the instrument. A discharged battery will be charged in this
situation, while the instrument remains in operation.
The power supply unit provided is intended only for indoor operation.
2.4.1
Operation Using the External Power Supply
The external power supply automatically adjusts to any AC input voltage between
90 V and 240 V nominal voltage.
Connect the USM Vision+ to the mains socket-outlet using the external power
supply with the appropriate power cable. The socket connector is under the cover on
the top side of the USM Vision+. Proceed as follows:
• Loosen the knurled screw in the cover on the top side of the instrument and
open the cover completely.
• Plug the Lemo connector of the external power supply unit into the socket
connector +15V until it snaps into place with a clearly-audible click.
• When pulling off the Lemo plug, withdraw the metal bushing on the plug
first in order to release the lock.
• When transporting the USM Vision+, always shut the cover and fasten the
knurled screw.
Note: When powering from mains operation, it is recommended that you use a
battery in the USM Vision+ in order to prevent a system failure and data
loss in case of a power failure.

Exchanging Batteries
Important: If you remove both batteries during operation and the instrument is
not connected to the mains supply, all unsaved data will be lost.
You can exchange one battery during operation as follows:
• First, insert a fully charged battery into an empty compartment.
• Then, remove the other battery.
2.4.5
Charging Batteries
You can charge the lithium-ion battery either directly in the instrument or by means
of an external battery charger. Several batteries are charged in succession.
If there is a battery in the instrument, the charging process starts automatically as
soon as you connect the external power supply. You can carry out ultrasonic tests
and charge a battery at the same time.
The charging time is approximately 6 hours per battery. Charging time is
independent of operation. The charging time applies to ambient temperatures from
25 °C to 30°C. Please keep in mind that the batteries are not charged to their full
capacity at high temperatures.
Charging lithium-ion batteries is also possible with the external battery charger
recommended and provided by GE Measurement & Control.
Note: You will find information on how to handle the external battery charger in
the documentation supplied with the charger.

2.5 Interfaces
Three USB sockets, a VGA socket and one network interface are located behind the
cover on the top side of the USM Vision+.
2.5.1
USB Sockets
The three USB Type A sockets offer multifunctional connection possibilities for
items such as a mouse, keyboard, printer or external data carriers.
Important: Do not use the USB Type B connector, as it may damage the USM
Vision+ or your computer.
Note: You will find information on the relevant software in the documentation
provided by the device manufacturer.
2.5.2
Network
For data transfer, you can connect the USM Vision+ with to Ethernet network. The
basic network functions are already set up, but have to be adapted and configured to
specific local network requirements.
2.6 The Trackballs and Touchscreen
2.6.1
Trackballs
The USM Vision+ features two trackballs to operate the graphical software
interface. The two trackballs work independently of each other.
Each trackball has a large button and a small button. Buttons on both sides of the
trackball have the same function. The big button confirms any selection or performs
the action of the button having the focus, while the small button cancels an action.
You can operate both trackballs simultaneously, such as moving the focus with the
right trackball while triggering functions with the buttons of the left trackball.

Chapter 2. Initial Startup and Operation
2.6.2
Touchscreen
The USM Vision+ is equipped with a touchscreen, enabling direct operation of the
menus appearing on the screen. This operation by direct touch replaces operation by
means of a mouse (selecting and clicking). A mouse pointer is therefore not
necessary. To select or to mark an element of the user interface, just touch the
corresponding point of the screen briefly.
CAUTION! Do not touch the touchscreen with any hard or
sharp-edged objects (e.g., ball-point pen or screwdriver). They
might severely damage the touch-sensitive surface. Do not apply
high pressure to the screen, as the touchscreen needs only slight
pressure to react.
2.7 Software Installation
The USM Vision+ is delivered completely configured and ready for operation.
2.8 Preparing the USM Vision+ for Use
When you unpack the USM Vision+, carefully remove the instrument, the probe,
the power supply and the cables from the shipping containers. Before discarding
any of the packing materials, account for all components and documentation listed
on the packing slip. If anything is missing or damaged, contact GE Measurement &
Control immediately for assistance
After you first receive the USM Vision+, you must insert the batteries into the
battery compartment on the bottom of the unit. You must then charge the batteries,
using the power supply included with the unit. When you start the USM Vision+,
you will need a user name and password from your system administrator to log onto
the system. Before beginning an inspection, you must also import an inspection
plan into the unit from a linked PC or USB memory stick and attach the probe to the
port at the top of the USM Vision+.

Predefined Color Palettes
Color Palettes that come with the instrument are predefined and cannot be
changed by the operator. The operator can only choose from the given list
for Amplitude and Depth.
3.5.1b
Custom Color Palettes
Unlike predefined palettes, the “Custom” Color palettes can be changed by
the operators. They can specify the number of colors and specify, for each
color, at which value it will end and the color value. There will be a selector
for predefined colors, but they can also access the RGB values for each
color.
3.5.1c
Color Interpolations
Some of the predefined Color Palettes support a linear interpolation between
colors. This option is not available for custom colors, which will be limited
to colors that switch on a threshold.
3.5.1d
Function Bar: Color Selection
In the Color Selection menu, users can switch between the Amplitude or
Depth Mode Palettes, and select which palette should be used for the
selected mode. For a custom palette, they can set the number of colors.

Figure 21: Color Range Menu
In the Color Range menu, the operator can specify the upper value for the selected
color range, select a predefined color for it, or modify the RGB value of the color in
the selected range.
Range End [% LSH] will be replaced by Range End [%Depth displayed] for
predefined depth palettes and changes Range End [mm] for the “Custom” depth
palette. Range End [mm] is valid from 0.0 to 6000.0 (as is RangeEnd in
UT->Range).
Color Index value is limited from 1 to “Number of Colors”. With color control, the
user selects from a list of seven predefined colors: black, red, green, blue, yellow,
white and gray. Changing any of the red, green or blue values will set Color to
Custom. Values for red, green and blue controls range from 0 to 255.

Step Control Functionality
The linear and T/R pattern describe an aperture sequence of sending and receiving a
beam with the same angle and focal depth from different elements of a phased array
probe.
In USM Vision+ ver. 9.4.0, users could specify the first probe element where the
first beam aperture should start. The pattern contained all apertures starting at the
first element and the following probe elements, until the last element of the aperture
reached the last element of the probe. Therefore the first element of the aperture
increased by one from beam to beam.
With version 9.4.1, the operator can set the increment to a value other than one.The
pattern can thus contain a lower number of beams, because the USM Vision +
reaches the last probe element more quickly.
3.7.1
Valid Value Range
The minimum value for this control is 1 the maximum is (No of channels - 1) which
calculates to 127 for the current USM Vision+ hardware.
3.7.2
Number of Beams in Pattern
The number of beams in a linear or T/R pattern is:
Number of Beams =
(Number of Probe Elements - (Start Element -1) - Aperture) / Linear Step + 1
3.7.3
Grey Out Logic
Control is greyed out during any calibration and when the USM Vision + is in scan
or analyze mode.

Sound Velocity Measurement
Figure 27: Sound Velocity Measurement
Sound velocity measurement is the topmost calibration menu. The interface appears
similar to Figure 27 above.
The operator enters backwall, radius, side drilled hole or flat bottom hole as Ref.
Type, and the distances /depths of the two reference reflectors as Ref. Dist D1 and
Ref. Dist D2. In addition, if the scan is other than sector, the operator needs to select
the beam for the measurement in the Display Views menu.
The instrument will set the natural beam angle when the operator presses the
START-button. Beam selection will be grayed out while sound velocity
measurement is active. The operator can choose the threshold of gate A as well as
the TOF measurement mode for gate A. Peak-mode is the typical setting for sound
velocity measurement.
In the example on the following pages, the linear probe 115-000-766 has been used
on a 10 mm aluminum plate, started with 6400 m/s as material velocity in menu
Part. When pressing the START-button, the instrument switches gate A on, and sets
it around the first reference distance (Start = D1 - 2 mm, if possible, and
width = 4 mm).
USM Vision+ User’s Manual

Chapter 3. Phased Array (PA) Mode
3.8
Sound Velocity Measurement (cont.)
The instrument activates the A-Scan + Frame - layout, and displays the envelope
curve in the A-Scan. An inverted V-icon is displayed while sound velocity
measurement is active. At any time the gain may be changed, and the envelope
curve will be generated again.
Figure 28: Envelope Curve in A-Scan
At any time the sound velocity measurement can be canceled by pressing the
CANCEL button. In this case, the former layout, start and width of gate A are
restored.
The Set UT range button enables users to quickly set a UT range around the two
reference distances / depths, when the current display does not show them:
Range start = (D1 - 2mm) - 0.25 * ((D2 + 2mm) - (D1 - 2mm))
Range end = (D2 + 2mm) + 0.25 * ((D2 + 2mm) - (D1 - 2mm)).
The operator now maximizes the first reference echo, and presses the STORE D1
button: The instrument will display the message “Measured TOF is invalid”, when
no echo has been detected in Gate A (This should only occur when the echo does
not intersect the gate bar in case of gate TOF measurement mode = flank, or in case
of “loss of echo in interface gate”, when range trigger = IF in menu range, which are
not typical settings for sound velocity measurement).

Sound Velocity Measurement (cont.)
Figure 29: Recording TOF
The instrument records the TOF of the highest echo of the envelope curve, within
the TOF range given by gate A start to gate A end, when the measured TOF value is
valid and positions gate A around the value of 'Ref Dist. D2' (Start = D2 - 2 mm, if
possible, and Width = 4 mm).
The operator now maximizes the second reference echo, and presses the STORE D2
button: The instrument will display the message “Measured TOF is invalid”, when
no echo has been detected in Gate A (for the same reasons as mentioned in D1
above).
The instrument records the TOF of the highest echo of the envelope curve, within
the TOF range given by gate A start to gate A end, when the measured TOF value is
valid, and calculates the sound velocity according to formula (2) of M. Berke
related document, and displays it as grayed out as Sound Velo (see Figure 30 on the
next page).

With ACCEPT the measured sound velocity is confirmed and assigned to the actual
part’s material velocity. The delay law calculation is then automatically applied, and
the sound velocity measurement is complete. The former layout, start and width of
gate A are restored, and a V-icon, which is not inverted, will be shown.

Range Trigger: IP Acquisition and IF Gate
The parameter “Range Trigger” in the UT Range menu has an additional mode, “IP
Acquisition and IF Gate.” In this mode, the A-Scan starts with the initial pulse (IP),
while gates A and B, and the TCG are triggered by the echo in the interface gate.
Thereby, the area between initial pulse and echo in the interface gate is displayed in
A-Scan and frame view, when the Range Start is set up accordingly.
To enable this mode, operators must select a linear scan with phasing angle = 0
degree, and the interface gate must be switched on.
Gate A and B are dynamically displayed in the A-Scan, which means that their gate
bars move as the echo in the interface gate moves. Gate A and B are not displayed
in frame view or side view. Frame view, side view and A-Scan are related to initial
pulse and are in sync.
When the top view will be generated from gated data (Gate A or B), it will be
relative to the echo in the interface gate. The readouts of gate A and B are also
relative to the echo in the interface gate.
As the start value of gate A or B must be a positive value, and gate A and B are
triggered by the echo in the interface gate, it is not possible to position gate A or B
before the echo in the interface gate.

Since all entered values are correct related to the probe and part, the system should
show almost correct signals, when coupled to K2, and optimizing the echo from
radius 25 mm. Gate values have been set to measure the two echoes from 25 mm

Creating a Dual Sector Scan for Weld Inspection
Once you have correctly set up and calibrated the first group, you can then “clone”
a second group from the first, e.g., for a double side simultaneous scan (dual scan).
You must use a so-called “Y-probe” (two probes sharing one connector). This
example uses the “Y-version” of the probe used for the single sector scan
calibration, as described in section 4.4, order number P/N 115-500-013.
Here, the two 16 element probes are connected via the Y-cable with one socket. On
the socket, probe #1 (left) uses pins 1 – 16, probe #2 (right) uses pins 33 – 48. Pin
Offset for probe #2 is 32.
Set up the 115-500-013 probe on 36° wedge (69438) with:
• Calibration on K2
• TCG recording with 4 points (10, 25, 40, 55mm)
• Sector from 40° - 70°, stored to file “2Sector_left”

Sensitivity Calibration
Sensitivity calibration is used to compensate any differences in sensitivity for every
shot (beam) of the current group, based on a known reference reflector in a given
depth.
Sensitivity differences are related to:
• Production differences for the individual elements in the Phased Array probe
• Beam steering
• Changes of delay line length due to shifting the virtual probe along the array
(electronic linear scan)
Sensitivity calibration is achieved by using the TCG calibration for just one single
given reference reflector (→ 1-Point TCG).
Before the TCG calibration can be started, the Delay Law Calculation (DLC) and
the Delay calibration must have been completed successfully. The examples in this
section are for a linear scan 0° with probe 115-500-016 in direct coupling and for a
sector scan 40° to 70° with MWB4PA.

1-point TCG (0° Linear Scan)

Sector Scan TCG Recording
TCG recording is used to compensate any differences in sensitivity for every shot
(beam) of the current group, based on several known reference reflectors of the
same size, but at different known depths. Apart from ACG (Angle Corrected Gain),
the losses due to beam divergence and sound attenuation will be compensated
within the range defined by the distances of the reference reflectors.
Before the TCG calibration can be started, the Delay Law Calculation (DLC) and
the Delay calibration must have been completed successfully.
In case one TCG point has already been recorded (e.g., for ACG), recording may be
continued by adding new reference reflectors in other depths.
IMPORTANT:
You must continue an already existing TCG with the same reflector
type and size! If you cannot, clear the existing TCG and start a
completely new one.
1. Set up the TCG according to Table 26 below. In this example, 3mm SDHs
will be used for TCG recording. No TCG has been stored before.

To establish the number of ticks per mm (or inch), enter the wanted scan length into

Appendix C. Environmental Compliance
Appendix C. Environmental Compliance
C.1 Waste Electrical and Electronic Equipment Directive
GE Measurement & Control is an active participant in Europe’s Waste Electrical
and Electronic Equipment (WEEE) take-back initiative, directive 2012/19/EU.
The equipment that you bought has required the extraction
and use of natural resources for its production. It may contain
hazardous substances that could impact health and the
environment.
In order to avoid the dissemination of those substances in our
environment and to diminish the pressure on the natural
resources, we encourage you to use the appropriate take-back
systems. Those systems will reuse or recycle most of the
materials of your end life equipment in a sound way.
The crossed-out wheeled bin symbol invites you to use those systems.
If you need more information on the collection, reuse and recycling systems, please
contact your local or regional waste administration.
Visit www.ge.com/inspectiontechnologies for take-back instructions and more
information about this initiative.
C.2 Battery Disposal
This product contains a battery that cannot be disposed of as
unsorted municipal waste in the European Union. See the
product documentation for specific battery information. The
battery is marked with this symbol, which may include
lettering to indicate cadmium (Cd), lead (Pb), or mercury
(Hg). For proper recycling return the battery to your supplier
or to a designated collection point.
USM Vision+ User’s Manual
141
Appendix C. Environmental Compliance
C.2.1 What do the Markings Mean?
Batteries and accumulators must be marked (either on the battery or accumulator or
on its packaging, depending on size) with the separate collection symbol. In
addition, the marking must include the chemical symbols of specific levels of toxic
metals as follows:
• Cadmium (Cd) over 0.002%
• Lead (Pb) over 0.004%
• Mercury (Hg) over 0.0005%
C.2.2 The Risks and Your Role in Reducing Them
Your participation is an important part of the effort to minimize the impact of
batteries and accumulators on the environment and on human health. For proper
recycling you can return this product or the batteries or accumulators it contains to
your supplier or to a designated collection point.
Some batteries or accumulators contain toxic metals that pose serious risks to
human health and to the environment. When required, the product marking includes
chemical symbols that indicate the presence toxic metals: Pb for lead, Hg for
mercury, and Cd for cadmium.
• Cadmium poisoning can result in cancer of the lungs and prostate gland.
Chronic effects include kidney damage, pulmonary emphysema, and bone
diseases such as osteomalcia and osteoporosis. Cadmium may also cause
anemia, discoloration of the teeth, and loss of smell (anosmia).
• Lead is poisonous in all forms. It accumulates in the body, so each exposure is
significant. Ingestion and inhalation of lead can cause severe damage to human
health. Risks include brain damage, convulsions, malnutrition, and sterility.
• Mercury creates hazardous vapors at room temperature. Exposure to high
concentrations of mercury vapor can cause a variety of severe symptoms. Risks
include chronic inflammation of mouth and gums, personality change,
nervousness, fever, and rashes.
