The information included in this manual applies to all QS5 series
ultrasonic corrosion and wall thickness gauges including models B, DL,
E and DLE.
dmq is a registered trademark of demeq S.R.L and its affiliate
companies.
The information contained in this manual is intended to educate users
on the operation of the QS5 gauges. Failure to read and understand
this manual can lead to measurement errors. Decisions based on
measurements and or results that are erroneous can lead to property
damage, personal injury or even death. Demeq S.R.L assumes no
responsibility as a result of the improper use of our instruments.
ASTM E797
The user must be trained in ultrasonic testing procedures and on how
to properly configure the unit for testing. All of the following should
be taken into consideration:
Understand the theory on sound wave propagation.
Select the instrument as well as the transducer that is best
suited for your application.
Know the specific requirements for the test you will be
conducting.
This manual provides all of the information needed to configure and
operate the QS5 gauge. However there are additional factors that can
VI
Page 9
affect tests done with this instrument. Specific information on those
factors is outside the scope of this manual. When in doubt you should
always seek expert advice or refer to specific textbooks on ultrasonic
testing. Additional information can also be found on the internet and
through local government agencies as well as in technical institutes.
The QS5 operates with dual crystal transducers that use the “pitchcatch” principal. Dual crystal transducers use two piezoelectric crystals
whereby one crystal is excited with short electrical pulses from the unit
sending short acoustic waves into the test piece. The second crystal
then receives the acoustic waves reflected at the end of the test piece.
The frequency of the acoustic waves changes between 2 and 10 MHz
depending on the probe being used.
All QS5 gauges operate in Echo-1 or normal (no coat) mode where a
measurement is the result of the sum of the time delay from the
transducer and the time it takes for the acoustic wave to rebound back
to the transducer after it reaches the end of the test piece. In Echo-2 or
thru-paint mode (QS5 E and QS5 DLE only), the unit measures the time
interval between the first and second echoes and does not take into
consideration the time delay from the transducer.
VII
Page 10
Figure 1: Echo-1 and Echo-2 mode acoustic wave representation
In ultrasonic testing information is obtained from measuring sound
waves. Users must be very careful when making assumptions in
regards to the entire test piece condition when there are areas that
have not been inspected. In large and massive test pieces it would be
practically impossible to test the entire piece and therefore conclusions
for the whole piece based solely on the areas that have actually been
inspected, should only be done by experienced operators. Only trained
users should evaluate test pieces that could present erosion and or
corrosion.
In order to minimize test result errors the following must be observed:
Before taking actual measurements the unit and transducer have to be
calibrated. Calibration of the transducer is also known as zero
calibration or delay calibration (Page 15). If the unit and transducer are
not calibrated, or calibrated incorrectly, the resulting measurements
will be unreliable. Each and every time a transducer is changed it must
be calibrated to the unit.
Because the sound velocities in materials will often vary significantly
from published values, best results are obtained when the instrument
is calibrated on a reference test block made from the same material as
that of the actual test piece. The block should be flat, of a smooth
finish, and be as thick as the maximum thickness of the test piece.
Careful consideration by the user must be made when evaluating the
accuracy of a thickness value because considerable changes in the
sound velocity of a material may have occurred as a result of a
treatment. So for example a test piece made of steel that has been
thermally treated, will look the same as a regular test piece made of
VIII
Page 11
untreated steel, but the sound velocities vary significantly. Instruments
should be calibrated before and after testing to minimize errors.
Transducers must be in good condition and show no visible signs of
excessive wear or defects on their surface. Badly worn transducers can
provide erroneous measurements.
The thickness of the material being tested must be within the specified
thickness range of the transducer and the temperature of the material
must also be within the specified temperature range of the transducer.
Calibration as well as actual testing should be performed under similar
coupling conditions. Couplant must be applied in an even and
consistent manner to minimize variations in couplant layers that may
result in testing errors. The amount of couplant should be kept to a
minimum and consistent pressure should be applied on the transducer
when measuring.
Doubling refers to a thickness measurement that displays a reading
that is twice or even three times the real test piece thickness. Doubling
often may happen when trying to measure below and above the
specified range for the transducer and when using worn transducers.
When in doubt, the test piece thickness must be measured using other
methods and or instruments and the unit must then be calibrated
using reference test blocks of known thickness values that are made of
the same material as the actual test piece. This is very important when
measuring unknown test pieces for the first time.
When possible calibrate your instrument on-site using a test block that
is at the same temperature as the test piece in order to minimize
errors.

All QS5 series corrosion and thickness gauges are for industrial use
only and cannot be used in medical applications. The QS5 operates on
two AA size batteries. We strongly recommend that you use only top
brand name alkaline batteries.
Disposal of your QS5 gauge and its components must be done in
compliance with all applicable regulations.
Because of its complexity level, software is never really completely error
free. For this reason in software controlled instruments always make
sure that the operations required for your application are in correct
working order.
Demeq S.R.L provides a limited warranty for a period of 2 (two) years
on electronic units and for 6 (six) months on transducers from the date
of purchase and may be extended for up to 5 years.
Every instrument undergoes thorough testing during manufacturing as
well as before shipping. In the event warranty service where to become
necessary, dmq and or your local distributor or representative will
make a reasonable effort to replace your defective unit with another
new or used unit, while your instrument undergoes warranty repair.

The QS5 is powered by 2 (two) AA batteries that are placed in the
battery compartment located in the back of the unit. To access to the
battery compartment slide the cover as shown in figure 1.3-1 and
gently push the extraction ribbon upward and slightly towards the
right to release the batteries (figure 1.3-2).
When you install new batteries, first insert the positive end of each
battery so that it coincides with the positive pole inside the battery
compartment as you see in figure 1.4-1. Always leave the extraction
ribbon underneath the batteries.

The QS5 has two type Lemo “00” connectors located on top of the
unit. Because this is the standard for most dual crystal probes, you
could basically connect any probe to your QS5. Keep in mind that the
gain may need to be adjusted when changing probes.
To connect the probe, simply align any
of the male connectors located at the
end of the transducer cable to any of
the female connectors located on the
gauge and press gently until
connected.
To release the probe hold the knurled
section on the male connectors and
pull gently away from gauge until
released.

The QS5 uses a zero (delay) calibration procedure that is activated by
simply coupling the transducer over the calibration disk located in
front of the unit.
Figure 2.6: Zero calibration procedure
When this automatic procedure ends, the unit is calibrated to measure
steel which is the default material velocity used in this calibration
method.
Chapter 2 15
Page 28
Tip
In order to measure the thickness of the calibration disk
without activating the automatic calibration procedure
simple touch the edge of the disk until an icon appears
as shown in (Figure 2.1, 8. Inactive calibration disk
indicator, Page 9) While still touching the edge of the
disk, couple the transducer to obtain its thickness
measurement. When the transducer is coupled you no
longer need to touch the edge of the disk.
16 Chapter 2
Page 29
In order to obtain precise measurements, especially when exchanging
transducers, the QS5 can be calibrated with your own test piece
samples. To access the two calibration modes available on the QS5, go
to the Ultrasonic menu (page 43) and enter the Calibr. option. Select
2-Points and follow the procedure below for calibration:
Figure 2.7: One point and two point calibration procedure
1. Measure using the calibration disk located in the unit front
panel.
The unit will proceed with the automatic calibration
procedure and “Calibrating” will be displayed on the unit
Chapter 2 17
Page 30
Notes
In the 2 point calibration procedure, the thickness of the
1st point (first test piece sample) MUST be lower than the
thickness of the second test piece sample.
The unit assumes that the material velocities of the test
piece samples are the same and that the correct velocity
has been set in the unit before the calibration procedure
was initiated.
Use of the unit calibration disk does not change the
velocity set by you.
screen. When the calibration is done, the unit will display
“Calibration… Done!”. At this point the unit will ask that you
measure the first test piece sample “Measure 1st Pt.” and
two additional options will be displayed: Edit and Exit.
2. Touch (Exit) to end the calibration using just the unit
calibration disk, or measure the first test piece sample.
3. After a measurement is displayed touch (Edit) to edit
the value using the cursor keys so that it matches the actual
test piece thickness.
4. When you are done editing the measurement, touch to
save and the unit will ask “Measure 2nd Pt.”.
5. When a measurement is displayed for the second test piece
simple, touch (Edit) to edit the value using the cursor
keys so that it matches the second test piece simple
thickness. When you are done editing the measurement,
touch to end the 2-point calibration procedure.

Tip
Touch the when editing velocity and a screen will
appear with the most commonly used materials and
their velocities. Use the cursor keys to scroll the list and
touch to select or touch to exit and return to
the edit velocity field.
If you know the velocity of the material you will be measuring you can
manually enter the velocity by doing the following:
Go to any numerical measure screen mode. If you are in
graphic BScan mode touch (BScan) to switch to normal
mode.
Touch from any numerical measure screen to enter the
Select / Edit mode.
Touch to edit the velocity field.
Use the cursors to set the velocity and touch to confirm
or touch to cancel.
If you do not know the velocity of the material but you know the
material thickness you can set the velocity using the material thickness
value by doing the following:
Measure the material for which you already know the
thickness.
Lift the transducer and touch to enter the Select / Edit
mode.
Chapter 2 19
Page 32
Note
When changing the material velocity using a known
thickness value the unit must have already been
calibrated for the transducer being used (Page 15).
Touch to select the thickness measurement field.
Use the cursors to set the thickness value and touch to
confirm or touch to cancel.
When editing the thickness value observe that the velocity will change
accordingly.
The QS5 has two controls (Trigger and Gain) that have a direct impact
on the ultrasonic signal process so that any dual crystal transducer can
be used and optimized for best performance.
The following image shows you how to interpret changes done to the
trigger level represented in higher and lower trigger values.
Figure 2.8: Representation of high and low levels of trigger
20 Chapter 2
Page 33
The image below shows how you to interpret changes done to the
gain level represented in higher and lower gain values:
Figure 2.9: Representation of high and low levels of gain
The trigger level determines the echo signals detected by the unit. A
higher trigger means lower sensitivity where only larger echoes are
detected. The gain level works like a “volume control on an audio
device”, the higher the gain setting the more amplified the echoes will
be.
A low trigger and a high gain are ideal in obtaining good sensitivity,
but if the trigger is set too low or the gain too high “noises” are
generated in the transducer that can result in erroneous or unstable
measurements. Transducers that are defective, badly worn or of poor
quality will also produce noises.
By default the unit always indicates whether the transducer is coupled
(measuring) or if the transducer is not coupled (in the air). But when
the analyzer option located in the Ultrasonic menu (page 47) is
Chapter 2 21
Page 34
Important
Material defects that are represented by the coupling
icons serve only as a warning and should not be
interpreted as definitive results. The specific area where
the possibility of a material abnormality is detected
should then be further inspected to confirm or discard
the warning.
activated the unit now also alerts the operator on the possible
condition of the test piece being measured. When the material
condition analyzer - available exclusively from dmq - is enabled, the
QS5 can display any of the following coupling icons:
Figure 2.10: Coupling icon representations
The analyzer only works in Echo-1 mode. When measuring in Echo-2 or
thru-paint mode the coupling icon will simply indicate that you are
measuring in that mode (represented with two parallel lines).
The vertical bar located on the far right side of the measuring screen
shows the echo signal intensity or energy level received by the
transducer giving you valuable information such as:
The coupling condition between the transducer and the test
piece.
The reflective (bottom) test piece surface condition where
22 Chapter 2
low energy levels would typically indicate the possible
presence of corrosion or pitting.
Page 35
The material attenuation level that allows the operator to
detect metal treatments that have an effect on the ultrasonic
characteristics of a material.
The QS5 has two modes for representing the energy absorbed by the
transducer:
No DAC: Shows only the energy level as provided by the transducer
With DAC: Compensates the energy level based on the measured
thickness. Use DAC to detect material conditions such as thermal
treatments and test piece defects easier regardless of the measured
thickness. DAC is activated in the Ultrasonic menu (page 47).
The higher the energy level reflected from the test piece bottom, the
higher the energy level will be on the vertical bar. This is an indication
of good coupling.
Low energy indicates any of the following: poor coupling (not enough
coupling gel), high attenuation materials (treated metals and some
plastics), an irregular test piece bottom surface (possible corrosion or
pitting) or if DAC is disabled it may be reflecting the test piece
thickness.
Figure 2.11: Vertical bar energy level representations
Chapter 2 23
Page 36
Tips
Sudden intensity loses usually mean that there are
defects in the test piece related to corrosion or pitting.
When measuring thick test pieces with DAC turned off,
the energy level decreases because a greater distance
(thickness) usually results in more attenuated echoes
being received by the transducer.
When a test piece made of steel that will typically return
high energy levels, is returning low energy, this usually
means that it was subject to thermal treatment. To
confirm or discard this possibility, measure the velocity
of the test piece. Steel that has been thermally treated
will have a different material velocity.
In case of low energy levels always make sure you have
good coupling and that you used enough coupling gel
to avoid erroneous interpretations.
When measuring in Echo-2 or thru-paint the energy level
may be low because the unit uses the energy produced
by the second echo which is normally smaller and more
attenuated when compared to the first echo used in
normal Echo-1 measurements.
24 Chapter 2
Page 37
The QS5 E and QS5 DLE gauges can measure thru-coatingings such as
paint or epoxy so you no longer need to scrape and remove the
coating in a test piece. The unit now “skips” the coating and measures
only the actual test piece thickness.
To enable thru-coating or thru-paint mode (Echo-2) touch the
(Echo) key from the measuring screen and the unit will display the
mode you are in. (Echo-1 normal, or Echo-2 coating (thru-paint).
Switch between Echo modes touching and wait until the window
indicating the mode you are in disappears. This means that the unit is
now set for the Echo mode you selected.
Figure 2.12: Change of Echo windows (normal or coating)
Multi-echo units use separate ultrasonic configurations for each echo
mode. This means that when switching between Echo-1 and Echo-2
modes the gain, trigger and voltage of the pulse emission are
maintained for each mode. In the example below the gain level for
Echo-1 is 75 and for Echo-2 it is 63. These gain levels will not change
as you switch modes.
Chapter 2 25
Page 38
Figure 2.13: Ultrasonic settings on each echo mode
All unit menu screens display an icon indicating the echo mode that
the unit is operating in.
Figure 2.14: Echo mode icon in menu screens
In Echo-2 mode the unit does not need to be calibrated and calibration
is actually blocked because when operating with multiple echoes the
delay in the transducer does not affect the thickness measurement.
To obtain precise and reliable measurements in Echo-2 mode the
following considerations and limitations should be considered:
The test piece coating should not exceed 2mm. This may vary
according to the attenuation of the coating material.
The thickness of the actual test piece should not exceed
25mm.
26 Chapter 2
Page 39
Lose or poor adherence between the coating and the test
piece can result in scattering of ultrasonic waves making it
impossible to measure.
Use sufficient coupling gel for stable coupling in order to
avoid erroneous or incorrect readings.
Always use dmq hi-damp transducers to measure in Echo-2
mode. Standard probes will not work correctly in this mode.

Figure 3.32: Transducer pulser excitation tension editor screen
Just like with the trigger and gain settings the pulser tension is set
separately for Echo-1 and Echo-2 modes.
Considerations when adjusting the pulser excitation tension:
Higher excitation or tension levels mean that more energy is applied to
the emissions crystal in the transducer making it easier to measure in
high attenuation and large or thick materials.
When measuring small or thin materials high tensions produce
saturated echoes that can affect measurement results particularly
when operating in Echo-2 mode.
Avoid high tensions particularly when using small diameter transducers
as this could damage the transducer. For 5MHz transducers the
tension should not exceed 150V. Large diameter transducers of a lower
frequency can be set to higher tensions for better performance.

In order to optimize the use of the Datalogger in your QS5 DL and QS5
DLE it is important that you understand how data is organized.
In the QS5 data is stored in 8 individual files with alphanumeric names.
Each file contains a grid with columns and rows. And each grid
contains columns (identified with consecutive letters; A, B, …AA, AB…)
that store an “N” number of values or measurements (batch). Each
value is identified with a column letter and a row number.

Do not measure outside the thickness range specified for the
transducer that you are using.
Use just enough coupling gel to ensure stable measurements. Avoid
using excessive coupling gel as it may be added to the thickness value
of the actual test piece being measured.
Always do the zero calibration using the calibration disk located in the
front of the unit particularly when changing transducers.
Have a reference test piece of the same material that you will be
measuring and know the velocity of the material or its thickness value
so that you can precisely determine the velocity of the material based
on its thickness.
Gain and trigger levels are set from factory with the optimal values
that correspond to the transducer that was shipped with your unit.
When a transducer is changed gain and trigger levels should be
adjusted to optimize transducer functionality.
