Introduction

Introduction

The PosiTector UTG is a hand-held Ultrasonic Thickness Gage
that uses the non-destructive ultrasonic pulse-echo principle to
measure the wall thickness of a wide variety of materials. It
consists of a body (Standard or Advanced) and probe (UTG C or
UTG M, see pg. 4).

The PosiTector UTG powers-up when the center navigation
button is pressed. To preserve battery life, the instrument
powers down after approximately 5 minutes of no activity. All
settings are retained.

1. Remove the protective rubber cap from the probe.

2. Power-up Gage by pressing the center navigation button.

3. Zero the probe (see pg. 10)

4. Select the correct velocity of sound (see pg. 11)

5. Measure the part (see pg. 6)

Certification

All PosiTector UTG probes include a Certificate of Calibration. For
organizations with re-certification requirements, instruments may
be returned at regular intervals for calibration.

DeFelsko recommends that customers establish calibration
intervals based upon their own experience and work environment.
Based on our product knowledge, data and customer feedback, a
one year calibration interval from either the date of calibration, date
of purchase, or date of receipt is a typical starting point.

To disconnect a probe from a body, power-down the
instrument and slide the plastic probe connector
horizontally (in the direction of the arrow) away from the
body. Reverse these steps to attach a new probe.

When powered-up, the PosiTector automatically
determines what type of probe is attached and does a
self-check.

Probes

Probes

PosiTector UTG probes transmit an ultrasonic pulse into the

material to be measured. This pulse travels through the material
towards the other side. When it encounters an interface such as air
(back wall) or another material, the pulse is reflected back to the
probe. The time required for the pulse to propogate through the
material is measured by the Gage, represented as t1and t2 below.

PosiTector UTG C and UTG M (in single-echo mode) probes
determine thickness by measuring t1(uncoated) or t2 (coated),
dividing it by two and then multiplying by the velocity of sound for
that material (steel). See Figure 1.

For uncoated materials t1relates directly to material thickness.
When a material is coated the propagation time is increased and

is shown above as t

.

Coatings such as paint have a slower velocity of sound than that
of metal. Thus the single-echo technique will produce a thickness
result greater than the actual combined coating+metal thickness.

The PosiTector UTG M in multiple-echo mode determines
thickness by measuring the time between at least three
consecutive back wall echoes.

In the figure above, multiple-echo mode measures only the time
between echoes. Regardless of whether the steel is coated or not,
all times between echoes are the same. In multiple-echo mode,
the Gage determines thickness by measuring t

1+t2+t3

, dividing it

by six and then multiplying by the velocity of sound for that
material. The resultant thickness calculation made by the
instrument is therefore an accurate measurement of the steel
thickness only, disregarding the coating thickness.

The velocity of sound is expressed in inches per microsecond or
meters per second. It is different for all materials. For example,
sound travels through steel faster (~0.233 in/µs) than it travels
through plastic (~0.086 in/µs).

Additionally, the PosiTector accepts a number of probe types
including magnetic and eddy current coating thickness, surface
profile, environmental and ultrasonic wall thickness probes.
Perform the latest software Updates (pg. 35) to ensure probe
compatibility with your Gage. For the latest information on probe
interchangeability see www.defelsko.com/probes

How to Measure

How to Measure

1. Remove rubber cap from probe. Couplant

(glycol gel - included) must be applied to the
surface to be tested to eliminate air gaps
between the wear face and the surface. A
single drop of couplant is sufficient when
taking a spot measurement.

2. Place the probe flat on the surface. Use moderate pressure to
press against the top of the probe with the thumb or index finger.
When the probe senses echoed ultrasound, a coupled symbol

will appear on the display and thickness values will be
displayed. While the probe is coupled, the PosiTector UTG
continually updates the display.

3. When the probe is removed from the surface, the last
measurement will remain on the display.

Occasionally, excess couplant will remain on the probe when the
probe is lifted from the surface. This may cause the PosiTector
UTG to display a final measurement value different from those
observed when the probe was on the surface. Discard this value
and repeat the measurement.

7

Surface Conditions

Surface Conditions

Ultrasonic measurements are affected by the condition,
roughness and contour of the surface to be tested.

Measurement results may vary on coarse surfaces. Where
possible, it is recommended to seat the transducer on a smooth
flat surface that is parallel to the opposite side of the material.

On rough surfaces, the use of a generous amount of couplant
minimizes the surface effects and serves to protect the transducer
from wear, particularly when dragging the probe across a surface.

During scanning operations, the probe can be become physically
decoupled, that is physically separated, from the material, either
due to the rough and/or scaly surface of the material or due to
user operation. Avoid this by using the Smart Couple

TM

feature

(pg. 17)

On smooth, uncoated metal surfaces the Gage
(in multiple-echo mode) may occasionally be unable to give a
measurement result even when the "coupled" symbol
appears. Use additional couplant and lighter pressure on the
probe when measuring. Alternatively, laying a plastic shim on the
surface with couplant applied to both sides to simulate a painted
surface will help produce a steel-only thickness measurement
(multiple-echo mode). Switching the Gage to single-echo SE
mode (pg. 16) will also help produce a steel-only thickness
measurement.

Calibration, Verification and Adjustment

Calibration, Verification and Adjustment

Three steps ensure best accuracy…

1.Calibration - typically done by the manufacturer or a qualified

lab. All probes include a Certificate of Calibration

2.Verification of Accuracy - as done by the user on known

reference standards such as calibration step blocks.

3.Adjustment - to a known thickness or sound velocity for the

material to be measured

Calibration

Calibration is the controlled and documented process of
measuring traceable calibration standards and verifying that the
results are within the stated accuracy of the Gage. Calibrations
are typically performed by the Gage manufacturer or by a certified
calibration laboratory in a controlled environment using a
documented process. The standards used in the calibration are
such that the combined uncertainties of the resultant
measurement are less than the stated accuracy of the Gage.

Written Calibration Procedures are available online at no charge
http://www.defelsko.com/downloads.htm

Verification

Gage accuracy can and should be verified using known reference
standards of the material to be tested.

Verification is an accuracy check performed by the user using
known reference standards. A successful verification requires the
Gage to read within the combined accuracy of the Gage and the
reference standards.

To guard against measuring with an improperly adjusted Gage,
verify the Gage at the beginning and the end of each work shift.
During the work shift, if the Gage is dropped or suspected of
giving erroneous readings, its accuracy should be re-verified.

Adjustment

Adjustment, or Calibration Adjustment is the act of aligning the
Gage's thickness readings to match that of a known reference
sample. See Calibration Adjustment pg. 10.

The center button is purposely recessed to help eliminate
unintentional powering-up of the instrument.

Cal Settings Menu

Cal Settings Menu

The PosiTector UTG is factory calibrated. In order for it to take
accurate thickness measurements of a particular material it must
be set to the correct sound velocity for that material. Be aware that
material composition (and thus its sound velocity) can vary from
stated tables and even between lots from a manufacturer.
Adjustment to a sample of known thickness of the material to be
measured ensures that the Gage is adjusted as close as possible
to the sound velocity of that specific material. Samples should be
flat, smooth and as thick as the maximum expected thickness of
the piece to be tested.

The PosiTector UTG allows four simple adjustment choices. All
four methods are based on the simple premise of adjusting the
sound velocity. The first three adjustment methods make 1-point
calibration adjustments to optimize the linearity of the PosiTector
UTG over small ranges. The fourth method makes a 2-point
calibration adjustment to allow for greater accuracy over a large
range.

Zero

PosiTector UTG probes can be "zeroed" to compensate for

temperature and wear. This action is not required when operating
in multiple echo mode (UTG M probes only) except when the
instrument is new and after a Reset (pg. 13). However, it ensures
best accuracy when operating in SE (single-echo) mode.
Therefore, it is a good idea to "zero" the probe before each work
shift and when the temperature of the part changes. During
zeroing, it does not matter what the current velocity setting is.

1. Make sure the instrument is on and the probe is wiped clean.

2. Apply a single drop of couplant onto the zero plate located on
the underside of the probe connector. DO NOT apply couplant
directly onto the probe face.

3. Select the Zero menu option and follow the on-screen prompts.

Calibration Adjustment

11

Thickness

The most common method of adjustment is to measure a sample
of known thickness. Select a reference standard of material as
close as possible in composition to the intended application. For
best results, the thickness of the reference standard should be
equal to or slightly greater than the thickness of the part to be
measured.

1. Apply a drop of couplant onto the reference standard.

2. Measure the reference standard.

3. Lift the probe. Select Thickness from the Cal Settings menu.

4. Adjust the display down (-) or up (+) to the reference thickness.

5. Press to the store the adjustment and exit.

Material

If a known thickness of the material is not available, but the
material is known, this quick adjustment allows the user to load
one of several preprogrammed material velocities.

1. Select Material from the Cal Settings menu.

2. Navigate to the desired material

3. Press to select and exit.

Velocity

If the sound velocity for the test material is known, the Gage can
be adjusted to that specific sound velocity

12

Cal Lock

ü

2 Pt Adjust

A 2-Point adjustment allows for greater accuracy while
simultaneously adjusting probe zero. Select two reference
standards as close as possible in composition to the intended
application. For best results, the thickness of the thicker reference
standard should be equal to, or slightly greater than the thickest
part to be measured. The thickness of the thinner reference
standard should be as close as possible to the lower end of the
expected measurement range.

1. Select 2 Pt Adjust from the Cal Settings menu.

2. Measure the thinner reference sample.

3. Lift the probe from the sample and adjust the display down (-)

or up (+) to the expected thickness.

4. When the expected thickness is reached, press

5. Measure the thicker reference sample.

6. Lift the probe from the reference sample and adjust down (-) or

up (+) to the expected thickness.

7. Press to store the adjustment and exit.

When checked, the icon appears and the current Cal settings
are “locked” to prevent further user adjustments. Uncheck to make
further adjustments.

Cal Reset

Clears all user calibration adjustments and returns the Material
back to Steel. The factory calibration icon is displayed.

1. Select Velocity from the Cal Settings menu.

2. Adjust the display down (-) or up (+) to the desired velocity.

Holding the (-) or (+) buttons increases the rate of change.

3. Press when the desired velocity is reached.

SmartCouple

ü

When selected, the probe, once coupled, will remain coupled until
the (+) button is pressed. Eliminates unintentional decoupling.

During scanning operations, the probe can be become physically
decoupled, that is physically separated from the material, either
due to the rough and/or scaly surface of the material or due to user
operation.

When this happens, analysis of the material stops and statistics
are displayed for only that portion of the surface to which the probe
was coupled. If the probe re-couples on purpose or accidently,
statistical values are reset to zero, and a new measurement
analysis session begins.

Due to the physical decoupling of the probe, the Gage may output
two or more independent measurement sessions. If the intention
was to measure the maximum and minimum thicknesses
continuously, erroneous indications may result due to the physical
decoupling of the probe from the material.

Smart Couple

TM

mode maintains a continuous measurement
session regardless of whether the probe becomes physically
decoupled from the material, and analyzes the thickness values of
the material at all locations where the probe was coupled.

This mode of operation provides a number of advantages. For
example, the user can make multiple passes between various
points of a material to be measured, and not have to actively
concentrate on ensuring that the probe is physically coupled to the
material. The user can therefore focus on the material itself, rather
than the instrument, or can focus more closely on the
measurement results displayed on the display. In addition, it
provides higher accuracy and faster scanning, since the user does
not have to stop and record between different scanning operations.
The user can deliberately lift the probe and scan a new area
knowing that all results will be analyzed if it were from one
continuous scan.

Coupled Smart Coupled

Connect Menu

Connect Menu

Auto SYNC

ü

Allows the Gage to automatically synchronize stored
measurements with PosiSoft.net when initially connected via USB
to an internet connected PC running PosiSoft Desktop Manager
(pg. 26).

Additional measurements added to memory while connected are
synchronized only when the USB cable is disconnected, then
reconnected or when the Sync Now option is selected.

Synchronizing (Sync) is the process whereby PosiTector stored
measurement data uploads to PosiSoft.net (from both Standard
and Advanced models) while images and batch notes are
downloaded to the Gage (Advanced model only). This transfer
occurs when the Gage is connected via USB, Bluetooth or directly
through your WiFi router/hotspot via WiFi. It can be triggered either
manually (USB, Bluetooth or WiFi) or automatically (USB only).

USB Drive

ü

Universal Serial Bus (USB) is a specification for communication
between devices and a host controller (usually a personal
computer). USB has effectively replaced a variety of interfaces
such as serial and parallel ports.

The PosiTector uses a USB mass storage device class which
provides a simple interface to retrieve data in a manner similar to
USB flash drives, cameras or digital audio players.

30

When checked, any computer can view datasets stored in memory
by navigating a virtual drive labeled “PosiTector” using the included
USB cable.

A formatted HTML report is viewed by selecting the "index.html" or
“START_HERE.html” file found in the root directory. Optionally, text
".txt" files located in each batch folder provide access to
measurement values. Stored datasets and graphs can be viewed
or copied using universal PC/Mac web browsers or file explorers.

When your PosiTector is first connected to your Windows PC via
a USB cable, an enumeration process is started that installs device
drivers without re-booting your computer. You may see several
pop-up windows in the taskbar at the bottom right of your screen.
Wait for the entire process to be completed before proceeding.

When connected, power is supplied through the USB
cable. The batteries are not used and the body will not
automatically power down. If rechargeable (NiMH) batteries are
installed, the instrument will trickle charge the batteries.

Application Notes

Application Notes

Measuring on pipes (UTG C probes)

When measuring the thickness of pipe walls, the proper placement
of the transducer is important. On pipe diameters larger than 10cm
(4 inches), it is recommended to place the probe parallel to the
long axis of the pipe. For smaller diameter pipes, it is
recommended that two measurements be taken, one with the
probe perpendicular, and another with the probe parallel to the
long axis of the pipe. The smaller of the two measurements should
be recorded as the thickness for that area.

Parallel - Better when measuring pipes with a diameter greater than
10cm (4 inches).

Perpendicular - Typically better when measuring small diameter pipes.

Measuring on rough surfaces

To optimize measurement results, the surface should first be
cleaned of any foreign debris including rust and scale. Depending
on the amount of contamination/ roughness, abrasion with a wire
brush or grinding tool may be necessary.

On rough surfaces, the use of a generous amount of couplant
minimizes the surface effects and serves to protect wear on the
transducer, particularly when dragging across the surface is
involved.

During scanning operations, the probe can be become physically
decoupled, that is physically separated, from the material, either
due to the rough and/or scaly surface of the material or due to user
operation. Avoid this by using the Smart Couple

TM

feature

(pg. 17).

37

Measuring on hot surfaces

Measurements taken at higher temperatures (above 100° C / 212°
F) require special consideration. Both material sound velocity and
probe zero will change with temperature. For maximum accuracy
at high temperatures, adjustment should be performed using a
material of known thickness heated to the temperature where
measurements are to be performed. The probe should remain on
the surface only as long as it takes to get a measurement.

The surface temperature of the test piece should not exceed (150°
C / 300° F).

Measuring laminated materials

The density (and thus sound velocity) of laminated materials often
varies considerably within a single piece or from piece to piece.
For best accuracy, perform a calibration adjustment to a sample of
known thickness. This sample should be as close as possible to
the density characteristics of the part to be measured. Be aware
that air gaps between laminates will likely cause strong reflections,
resulting in the Gage measuring a lower thickness value than the
actual total thickness.

Calibration

Measurement accuracy is directly related to the accuracy and care
taken when performing a gage calibration adjustment. Adjustments
will likely be required whenever the test material or temperature
changes. Periodic checks with samples of known thickness are
recommended to verify that the Gage is operating properly.

Taper or Eccentricity

If the measured surface and the back wall are not parallel to one
another, measurement accuracy may be diminished due to a
distorted echo.

Sound Scattering

Some materials have conditions which can limit the accuracy and
thickness range of the Gage. For example, individual crystallites in
cast metals and dissimilar materials in composites can scatter the
ultrasonic pulse. The return echo may be too weak for the Gage to
effect a measurement.

38

Troubleshooting

Troubleshooting

Some common reports received by our Service Department along
with possible causes. Most conditions however can be cleared
with a Reset (pg. 13).

Probe continues to measure after lifted from surface

Wipe away any excess couplant on probe tip.

Gage fails to power down

Ensure the probe is clean and free of couplant. The Gage will not
turn off if coupled symbol is displayed on LCD.

Gage is coupled, but not measuring

See Surface Conditions, pg. 7.

Gage readings appear to be double the expected thickness

This sometimes occurs near the minimum measuring range of the
instrument. The first return echo is unmeasurable, so the Gage
measures the second return echo. The resultant calculation is
double the actual thickness.

Measurement jumps as probe is lifted from surface

Occasionally, excess couplant will remain on the probe when the
probe is lifted from the surface. This may cause the PosiTector
UTG to display a final measurement value different from those
observed when the probe was on the surface. Discard this value
and repeat the measurement.

UTG C and UTG M probes

39

Gage displays -.-- (dashed lines) when measuring on an
smooth uncoated surface in multiple echo mode

See UTG M probes note on pg. 5

Gage is coupled, but not measuring

On smooth, uncoated metal surfaces the Gage (in multiple echo
(ME) mode) may occasionally be unable to give a measurement
result even when the "coupled" symbol appears. Use additional
couplant and lighter pressure on the probe when measuring.
Switching the Gage to SE mode (pg. 16) will also help produce a
steel-only thickness measurement. Alternatively, laying a plastic
shim on the surface with couplant applied to both sides to simu­late a painted surface will help produce a steel-only thickness
measurement in ME mode.

When measuring non-parallel surfaces, ME mode does not
display a reading

Measurement accuracy may be diminished when ME mode is
used to measure a part that has non-parallel surface and back
walls. A distorted echo or no echo at all may result. Switch to SE
mode (pg. 16) and retry.

Thickness values are repeatable, but seem incorrect

1. When measuring thick, hard coatings on thin metal, ME and SE
modes may both give improper results. This unusual condition
results in many gages interpreting the thick coating as the metal
and the thin metal as a coating on the backside. The Gage
therefore displays the thickness of the coating using the velocity
calibration for the metal. This application may not be measurable.

Or

2. The Cal Settings property may be incorrect. For best accuracy
the Gage must be set to the correct sound velocity for that
material (see pg.11).

Or

3. Too much loose rust or scale may be present on the surface.
Scrape away loose material with a wire brush or scaper and apply
sufficient couplant. In extreme cases, rotary sanders or grinding

UTG M multiple echo (ME) probes only

40

wheels may be necessary using care not to gouge the surface.

Or

4. There may be a coating on both sides of the metal. Switch to SE
mode for best results.

ME (multiple echo) and SE (single echo) results are not the
same

When measuring a COATED piece of metal, ME and SE modes
will likely produce different thickness values as expected. The ME
value will be thinner since it represents the thickness of only the
metal (ignores the coating).

Measurements of an UNCOATED piece of metal, however, should
be the same (within tolerance) except in the following
circumstances…

Surface Roughness, scale, etc.

ME mode may produce thinner measurement results because it
may ignore the surface roughness in much the same way it ignores
coatings.

41

Flaws, voids or pits

A void or flaw inside a metal object is better detected in SE mode
where the Gage will measure the distance from the surface down
to the flaw. Scan-mode will help locate the flaw. In ME mode the
Gage may not “see” the flaw and will display a thicker, total
thickness value.

Measuring the depth of a rod

ME mode may produce accurate results in situations where SE
mode may not be able to measure at all.

Probe pressure

Applying too much hand pressure on the probe while measuring
may squeeze out too much couplant and make it difficult for ME
mode to effect a measurement.

Temperature

Probe temperature: ME values are not affected by temperature
changes within the probe. But the Gage should be zeroed (pg. 10)
for best accuracy when operated in SE mode.

Metal temperature: Sound waves travel faster when the material is
heated. Preprogrammed sound velocities within the PosiTector
UTG are valid for normal temperatures in the vicinity of 15°C and
must be adjusted for extreme temperatures. For best results in
either mode, the Gage should be adjusted to the known thickness
of the material at a temperature similar to the part being measured.

42

The battery indicator displays a full bar with fresh alkaline
or fully charged batteries installed. As the batteries weaken, the
bar will be reduced. When the battery symbol is low
the Gage can still be used, but the batteries should be changed or
recharged at the earliest opportunity. The Gage will turn off
automatically when batteries are very low, preceded by a Low
Battery Warning on the display.

To retain all user settings and stored memory readings, only

replace the batteries after the Gage has powered-down.
