Preparing the Measurement Surface
1. Clean any dust, dirt or rust off the object, and remove any coating
such as paint.
2. Smooth the surface of the object by grinding or polishing it. You can
also use a coupling gel with a high viscosity.
Important Note: In any ultrasonic measurement scenario, the shape and
roughness of the desired test material are of great importance. Rough,
uneven surfaces will prevent the ultrasonic sensor from seating properly
against the surface, thus limiting the penetration of ultrasound through the
material, resulting in unstable and therefore, unreliable measurements.
Taking Thickness Measurements
1. Set the sound velocity on the meter (see Adjusting the Sound
Velocity for details).
2. Apply coupling gel on the material, place the sensor rmly against
the desired measurement area.
Note: For most applications a single droplet of coupling gel is sufcient.
3. Verify that the coupling Indicator "

6. Press the button to save the measurement if applicable.
7. If the coupling indicator " " does not appear on the display,
or the measured values appear to be erratic, verify that there is an
adequate amount of coupling gel in between the ultrasonic sensor
and the material under test. It is also important that the ultrasonic
sensor sits at against the material.

Minimum Capture Measurements
When the ultrasonic sensor couples with the test piece it will display the
current measurement. When it is lifted away it will display the minimum
value of the measurement carried out while the MIN Indicator ashes for
several seconds. Measurements taken during the MIN indictor ashing
cycle will continue to be part of the minimum value capturing. If you carry
out measurements after the MIN Indicator stops ashing the minimum
value capturing will re-start. The MIN indicator will only display when the
minimum capture function is ON (see System Setup section for details).
Measurement Methods
There are three base measurement methods:
1. Single measurement method: This method involves measuring the
thickness at a single point.
2. Double measurement method: This method
involves performing two thickness measurements
near a single spot rotating the ultrasonic sensor
from 0 to 90° respectively, with respect to the split
face (see Figure A).Take the smaller of the two
indicated values as the thickness of the material.

Maintenance
Cleaning the Test Piece
After taking a measurement, clean the test pieces to prevent them from
rusting. If the pieces are not to be used for a long period of time, coat
them with oil to prevent rust.
Protecting the Ultrasonic Sensor
Be sure to clean the ultrasonic sensor and cable after each use. Grease, oil
and dust will cause the cable to dry out and shorten life expectancy. The
temperature of the surface being measured should not exceed 140°F (60°C).
Replacing the Ultrasonic Sensor
The degradation and wear of the probe's interlayer plate will inuence
measurements. Replace the probe when the following occurs:
•
If it always displays the same value when measuring different
thicknesses or;
•
When a measurement displays no value.

Appendix
Measurements on Cylindrical Surfaces
When measuring cylindrical material, such as pipes or oil tubes, it is
important to properly adjust the angle between the ultrasonic sensor's
crosstalk interlayer plate and the axial line of the material being measured.
1. Couple the sensor with the material being measures.
2. Make the sensor's crosstalk interlayer plate perpendicular or parallel
to the axial line of the material under test.
3. Shake the sensor vertically along the axial line of the material under
test, the readouts displayed on screen will change regularly.
4. Use the minimum readout.
The standard for selecting the angle between the sensor's crosstalk
interlayer plate and the axial line of the material under test depends on the
curvature of the material under test. For a pipe with a large diameter the
sensor's crosstalk interlayer plate should be perpendicular to the axial line of
the material under test. For a pipe with small diameter, the sensor's crosstalk
interlayer plate can be both parallel and perpendicular to the axial line of the
material under test, and take the minimum readout as the thickness.
Measuring Compound Profiles
When the material being measured has a compound prole (such as
a bend in a pipe), one can use the procedures to measure cylindrical
surfaces. The exception is that one should have two analyses and get
two results when the sensor's crosstalk interlayer plate is both parallel
and perpendicular to the axial line of the material under test. Take the
minimum readout as the material thickness.
Measuring an Un-Parallel Surface
To get a satisfactory ultrasonic response, the other surface of the
material under test must be parallel to or co-axial with the surface being
measured, otherwise it will cause a measuring error or even provide no
displayed reading.
www.GlobalTestSupply.com
continued...
18
Influence of Material's Temperature
Both the thickness and transmitting speed of ultrasonic waves are
inuenced by temperature. If there is a high requirement of measuring
accuracy, please use one of the comparison methods listed below:
1. Use a test piece of the same material being measured, under the
same temperature.
2. Obtain the temperature compensation coefcient.
3. Use this coefcient to correct the actual measurement of the material
being tested.
Material with Large Attenuation
Material with porous and coarse particles (such as bre) will cause a large
scatter and energy attenuation in the ultrasonic wave. This will cause
abnormal readings or provide no readings on the display (generally, the
abnormal readings are less than the actual thickness). These type of
materials cannot be measured by our ultrasonic thickness gauges.
Measuring Castings
Castings will cause large attenuations in sound energy due to coarse
crystal particles and a not-so-dense structure. The attenuation is due to
the material's scatter and absorption of sound energy. Coarse out-phase
structures and coarse crystal particles will cause abnormal reection (i.e.
a grass-shaped or tree-shaped echo) resulting in errors in the readings.
When the crystal particle is coarse, the anisotropy in exibility in metal's
crystallizing direction will be obvious. This results in difference in sound
velocities in different directions, with the maximum difference being up to
5.5%. The compactness in different positions of the workpiece is different,
which will also cause difference in sound velocity. All of these will produce
inaccuracies in the measurements.
While measuring castings pay attention to the following:
1. When measuring casting with an un-machined surface use engine
oil, consistent grease, or water glass as a coupling gel.
2. Calibrate the sound velocity for the material under test with a
standard test piece having the same material and measuring
direction as that of the material being measured.
3. If necessary, take a 2-point calibration.

Preventing Errors
Reference Test Pieces
To maintain high accuracy when taking measurements of different
materials, it is important to use a standard test piece that resembles the
material and conditions being measured. The ideal reference test pieces
should be a group of test pieces with different thicknesses made of the
same materials that is going to be measured. The test pieces can provide
calibrating factors for the meter (such as the microstructure of the material,
heat-treating condition, direction of particles, surface roughness, etc.).
To meet the highest requirements of accuracy a set of reference test
pieces are critical.
Under most situations satisfactory measuring accuracies can be met
with only one reference test piece. This should be the same material and
similar thickness to the material under test. Take an even-surfaced object,
measure it by using a micrometer, then use it as a test piece.
For thin material, when its thickness is near to the low limit of the sensor's
measuring range, you can use a test piece to determine the accurate low
limit. Never measure a material with a thickness lower than the low limit.
When the material under test is thick, especially an alloy with complex
internal structure, select a test piece similar to the object from a group of
test pieces, giving you an idea of calibration.
For most casting and forging, their internal structures have some direction.
In different directions, the sound velocity will experience some change. To
solve this problem, the test piece should have an internal structure with
same direction as that of the material under test, and the transmitting
direction of sound wave in it should also be same as that of the material.
Under certain circumstances, referring to a material speed-of-sound
table can replace reference test pieces. The value in the speed-of-sound
table may have some difference from the actual measured values due to
difference in the material's physical and chemical characteristics. This is
usually used for measuring low-carbon steel, and can only be taken as a
rough measurement.
www.GlobalTestSupply.com

20
Ultra-Thin Material
An error will occur when the thickness of a material under test is less
than the low limit of the ultrasonic sensor. When necessary, measure the
minimum limit thickness by comparing it with test pieces. When
measuring an ultra-thin material, sometimes errors called "double
refraction" may occur. This results in a displayed measuring reading that is
twice the actual thickness of the material under test. Another error result is
called "pulse envelop or cyclic leap". This results in the measured value
being larger than the actual thickness. To prevent these kinds of errors
repeat the measurement to conrm the results.
Rust, Corrosion, and Pits
Rust and pits on the surface of the object will cause irregular change in
the measured reading. In extreme situations it will even cause no readings
on the display. To avoid errors, orient the sensor's crosstalk interlayer
plate in different directions to take multiple measurements.
Error in Identifying Material
If you calibrate the meter with one material and then measure another
material, an error will occur. Be careful in selecting the correct sound velocity.
Degradation of Probe
The surface of the probe is allyl resin. Over time its roughness will increase
resulting in reduced sensitivity. If it is determined that this is the reason for
the errors, grind the surface with sandpaper or oilstone to make it smooth
again. If the readings are still not stable, the sensor must be replaced.
Overlapped Material and Compound Material
It is impossible to measure uncoupled overlapped material because
the ultrasonic wave can't pass through an uncoupled space. Since the
ultrasonic wave can't transmit in a compound material in even speed you
cannot use an ultrasonic thickness-gauge to measure overlapped material
and compound material.
Influence of Metal Surface Oxidation
Some metals can produce a dense oxidation layer on the surface, such
as aluminum. Even though the layer is in close contact with the substrate
and provides no obvious interface, the ultrasonic wave will have different
transmitting speeds in these two materials which will cause an error.
continued...
21
www.GlobalTestSupply.com
In addition, different thicknesses in oxidation layers will cause different
errors. Make a reference piece from a batch of objects by measuring with
a micrometer or calliper, and using it to calibrate the instrument.
Abnormal Readout of Thickness
The operator should be able to identify an abnormal measuring reading.
Generally the rust, corrosion, pit, and internal defect of the material under
test will cause abnormal measuring readings.
Utilization and Selection of a Coupling Gel (R7950)
Coupling gel is used for transmitting high-frequency energy between the
ultrasonic gel and the material under test. If the type of gel or utilization is
wrong, or the utilization it will cause an error. For most applications a single
droplet of coupling gel coated evenly is sufcient. When measuring a smooth
surface use a gel with low viscosity (such as the coupling gel provided or
light engine oil). When measuring a coarse object surface, vertical surface or
top surface, use a gel with high viscosity (such as glycerin grease, consistent
grease, and lubricating grease, etc.).
