Disclaimers and Notices
The following information must be read a
nd understood by users of the
Sonatest Sitescan
D-10 & D-20
ultrasonic flaw detector
and thickness
gauge.
Failure to follow these
instructions can lead to serious errors in test results or damage to the flaw detector.
Decisions based on erroneous results can lead
to property damage, personal injury or
death.
Anyone using this instru
ment should be fully qu
alified by their organization in the
theory and practice of ultrasonic testing, or
under the direct supervision of such
a person.
2.1
Specific Warnings
The Sitescan D-10 & D-20
contains a high-energy, precision pulser allowing optimum testing
results to be
obtained by mat
ching the pulse width
to the probe character
istics.
This
circuitry may be damaged
by voltage spikes.
It is recommended that the instrum
ent be
switched
off,
or
the
pulser
stopped
(by
pressing
the
key)
before
changing
transducers
(probes).
2.2
General Warnings
Proper use of the
ultrasonic test equipment requires three essential elements:
•
Knowledge of the specific
test or inspection and applicable test equipment.
•
Selection of the correct test
equipment based on knowledge of the
application.
•
Competent training of the instrument operator.
This user’s guide provides instruction in the basic operation of the Sitescan D-10 & D-20
flaw detector.
In addition to the methods included, m
any other factors can affect the use of
this flaw detector.
Specific information
regarding these factors is
beyond the scope of
this
manual.
The user should refer to appropriate textbooks on t
he subject of ultrasonic testing
and thickness gauging for more detailed
information.
2.3
Operator Training
Operators must receive adequate training before using this
ultrasonic flaw detector.
Operators must be trained in general ultrasonic testing procedures and
in the set-up and
performance required b
y each specific test or inspection.
Operators must understan
d:
•
Sound wave propagation theory.
•
Effects of the velocity of sound in the test material.
•
Behaviour of the sound wave at the interface of two different materials.
•
Sound wave spread and mode conversion.

Sitescan D-10 & D-20 User’s Guide ~ Disclaimers and Notices
Page 3
More specific information about operator training, qualification, certification
and test
specifications can be obtained from technical societies,
industry groups and government
agencies.
2.4
Testing Limitations
In ultrasonic testing, information is obtained only from
within the confines of the
sound
beam as it propagat
es into the test mater
ial.
Operators must
exercise great caution
when
making inferences about the nature of the test material outside the limits of the sound
beam.
The condition of materials can vary significan
tly and the results can be erratic
if
operators don’t exercise good judgment.
2.5
Critical Operating Factors
The following procedures must be observed
by all users of this
ultrasonic flaw detector in
order to obtain proper and accurate results.
2.5.1
Calibration of the Sound Velocity
An ultrasonic flaw detec
tor operates on the principle of measuring
the time of flight of a
burst of high frequency sound through the test piece as well as evaluating the amplitude of
reflected or transmitted
echoes.
The sound velocity of the test piece multiplies
this time in
order to obtain an accurate d
istance or thickness reading.
Since the actual sound velocity
in
materials can vary from the published values,
the best result is
obtained when the
instrument is calibrated on a reference block made from the same material as the test piece.
This block should be flat, smooth and as thick as the maximum thickness expected of the
test piece.
Users should also be aware that the sound velocity might not be constant throughout the
test piece due to effects such as heat-treating.
This must be taken into con
sideration when
evaluating the resul
ts of ultrasonic thic
kness testing.
The calibration should alway
s be
checked after testing to minimize errors.
2.5.2
Transducer (Probe) Zero Procedure
The transducer calibrat
ion procedures must be perform
ed as described in this manual.
The
calibration block must be c
lean, in good condition and free of n
oticeable wear.
Failure to
perform the transducer zero and calibration procedure will cause inaccurate thickness
readings.
2.5.3
Flaw Detection Calibration
When performing flaw detection, it is im
portant to note that the amplitude of ind
ications is
not only related to the size of the discontinuity; the depth of a discontinuity below the test
piece surface will also have an effect on the amplitude due to characteristics of the sound
beam spread and near field zone of t
he transducer.
In addition, the characteristics of the
discontinuity such as orientation and classification can alter the
expected amplitude

Sitescan D-10 & D-20 User’s Guide ~ Disclaimers and Notices
Page 4
response.
For these reasons, calibration
should be performed
on test blocks
made of the
same material as the test piece with artificial discontinuities within the range of size and
depth in the mater
ial to be detected
.
The user is again c
autioned to refer
to reference
books which are beyond the scope of this manual.
2.5.4
Effects of Temperature on Calibration
The sound velocity in test pieces and the transducer wear face changes with temperature
variations.
All calibrations should be perfor
med on site with test blocks at or near t
he same
temperature as that expected on the test piece, to minimize errors.
2.5.5
Transducer Condition
The transducer used for testing must be
in good condition, without noticeable wear of
the
front surface.
The specified range of the transducer mu
st encompass the complete ran
ge of
the thickness to
be tested and/or the
types of discontinu
ities to be investigated.
The
temperature of the material to be tested must be within the transducer’s specified
temperature range.
2.5.6
Use of Couplant
Operators must be familiar w
ith the use of ultrasonic couplant.
Testing skills must be
developed so that couplant is used and
applied in a consistent manner to
eliminate
variations in couplant thickn
ess which can cause errors an
d inaccurate readings.
Calibration
and actual testing should be performed under similar coupling conditions, using a
minimum amount of couplant and applying consistent pressure to the transducer.

Quick Start
3.1
Front Panel
The main control on the front of the unit is the scroll-wheel that is
used to navigate through
the menus and to adjust parameters this, along with the
lh
key in the middle of the wheel
allows quick and intuitive navigation.
Moving your finger in a clockwise direction moves the top line menu selection to the right
and increases a sel
ected parameter.
Moving your finger
in an anticlock
wise direction moves
the top line menu
selection to the left an
d decreases a
selected parameter.
The right arrow
moves the top menu selection right by one increment at a time, the left arrow moves it left
by one increment.
The down arrow moves down t
he four parameter boxes on the right of
the display while the
up arrow mov
es up.
When a parameter is select
ed using the
lh
button the up and down arrows change the
value by small increments while the
right and
left arrows change the value by a bigger increment.
The remaining front panel controls consist of a series sealed, pressure sensitive, tactile
buttons that have specific functions assigned to them; the exception to this are the four
"user" buttons that can be assign
ed to any menu item or a list of u

These buttons move the highlighted cursor along the top of the screen left
and right to the sub menu to be selected, they are also used to make large
increment changes to
a selected parameter.
These are momentary
buttons
with no repeat.
The parameter boxes along the right hand side of the screen
change as the sub menu is selected.
This button moves the selection of the parameter boxes on the right of the
screen up, it is also used make small increment changes to a selected
parameter.
