1.0 INTRODUCTION
The Electromatic Model TI-007DL is a precision Ultrasonic Micrometer. Based on
the same operating principles as sonar, the TI-007DL is capable of measuring the
thickness of various materials with accuracy as high as ± 0.0001 inches, or ± 0.001
millimeters. The principle advantage of ultrasonic measurement over traditional
methods is that ultrasonic measurements can be performed with access to only one
side of the material being measured.
This manual is presented in three sections. The first section covers operation of the
TI-007DL, and explains the keypad controls and display. The second section provides
guidelines in selecting a transducer for a specific application. The last section provides
application notes and a table of sound velocity values for various materials.

2.0 OPERATION
The TI-007DL interacts with the operator through the membrane
keypad and the LCD display. The functions of the various keys
on the keypad are detailed below, followed by an explanation of
the display and its various symbols.
The Keypad
This key is used to turn the TI-007DL on and off. When the TI-007DL is
turned ON, it will first perform a brief display test by illuminating all of the
segments in the display. After one second, the tool will display the internal
software version number. After displaying the version number, the display will show
“0.0000” (or “0.000” if using metric units), indicating the tool is ready for use.
The TI-007DL is turned OFF by pressing the ON/OFF key. The tool has a special
memory that retains all of its settings even when the power is off. An auto-powerdown
mode conserves battery life. If the tool is idle for 5 minutes, it turns off.
The IN/MM key is used to switch back and forth between English and
metric units. This key may be used at any time, whether the tool is displaying
a thickness (IN or MM) or a velocity value (IN/µs or M/s).
The CAL key is used to enter and exit the TI-007DL’s calibration mode.
This mode is used to adjust the sound-velocity value that the TI-007DL will
use when calculating thickness. The tool will either calculate the sound-
velocity from a sample of the material being measured, or allow a known velocity
value to be entered directly. Refer to page 6 for an explanation of the two CAL
functions available.
The MODE key is used to toggle through features and settings of the
TI-007DL (alarm, diff, scan, gate, back light, and beeper). The MODE key
is used in conjunction with the arrow and send keys to enable/disable the
features and settings. Refer to page 8 for a further explanation of the different modes.
The UP arrow key has three functions. When the TI-007DL is in calibration
mode, this key is used to increase numeric values on the display. An auto-
repeat function is built in, so that when the key is held down, numeric values
will increment at an increasing rate. When MODE is activated, the UP arrow key
scrolls through the various features and settings of the TI-007DL. When the data log-
ging feature has been activated by pressing the MEM key, the UP arrow is used to
scroll through the various fields, storage locations, and functions for the data logger.
Refer to page 11 for further information regarding the use of the UP arrow key and the
data logger.
The DOWN arrow key has three functions. When the TI-007DL is in the
CAL mode, this key is used to decrease numeric values on the display. An
auto-repeat function is built in, so that when the key is held down, numeric
values will decrement at an increasing rate. When MODE is activated, the DOWN
arrow key scrolls through the various features and settings of the TI-007DL. When the
data logging feature has been activated by pressing the MEM key, the UP arrow is
used to scroll through the various fields, storage locations, and functions for the data
logger. Refer to page 11 for further information regarding the use of the UP arrow key
and the data logger.

The MEM key enables /disables the data logging feature of the TI-007DL.
This key is used in conjunction with the UP/DOWN arrows, SEND, and
CLR keys (hi-lighted in green). The combination of these keys control the
data logging features of the TI-007DL. Refer to the data logging section on page 11.
The CLR key is specifically used with the data logging feature of the
TI-007DL. This key clears the contents of an entire file, or individual
storage locations. The CLR key is also used to send an obstruct (ObSt) to
an individual storage location. The ObSt symbol would indicate that the user was
unable to take a reading at a particular locations, see data logging section on page 12.
The SEND key is used for sending data to internal storage locations and
external peripheral devices (serial printer/computer) The SEND key is also
used to select data logging functions in the TI-007DL, page 12.
The Display
The numeric portion of the display consists of 4 complete
digits preceded by a leading “1”, and is used to display
numeric values, as well as occasional simple words, to
indicate the status of various settings. When the TI-007DL
is displaying thickness measurements, the display will hold
the last value measured, until a new measurement is made.
Additionally, when the battery voltage is low, the entire
display will begin to flash. When this occurs, the batteries
should be replaced.
These eight vertical bars form the Stability Indicator.
When the TI-007DL is idle, only the left-most bar and the
underline will be on. While the gauge is taking a measure-
ment, six or seven of the bars should be on. If fewer than
five bars are on, the TI-007DL is having difficulty achieving
a stable measurement, and the thickness value displayed will
most likely be erroneous.
When the IN symbol is on, the TI-007DL is displaying a
thickness value in inches. The maximum thickness that
can be displayed is 1.999 inches.
When the MM symbol is on, the TI-007DL is displaying a
thickness value in millimeters. If the displayed thickness
exceeds 19.999 millimeters, the decimal point will shift auto-
matically to the right, allowing values up to 99.99 millime-
ters to be displayed.
When the IN symbol is on, in conjunction with the /µs
symbol, the TI-007DL is displaying a sound-velocity value
in inches-per-microsecond.
When the M symbol is on, in conjunction with the /s
symbol, the TI-007DL is displaying a sound-velocity value
in meters-per-second.

8.0 APPENDIX B — APPLICATION NOTES
Measuring tubing
When measuring a piece of tubing for wall thickness, it may prove beneficial to have
multiple delay lines with different radiuses for different tubing diameters. The delay
lines can be easily radiused by placing a piece of emery cloth around the tubing and
moving the transducer back and forth until a radius has formed on the tip of the delay
line.
Measuring hot surfaces
The velocity of sound through a substance is dependent upon its temperature. As mate-
rials heat up, the velocity of sound through them decreases. In most applications with
surface temperatures less than about 200 °F (100 °C), no special procedures must be
observed. At temperatures above this point, the change in sound velocity of the materi-
al being measured starts to have a noticeable effect upon ultrasonic measurement.
At such elevated temperatures, it is recommended that the user perform a calibration
procedure (refer to page 6) on a sample piece of known thickness, which is at or near
the temperature of the material to be measured. This will allow the TI-007DL to
correctly calculate the velocity of sound through the hot material.
When performing measurements on hot surfaces, it may also be necessary to use a
specially constructed high-temperature delay line. It is recommended that the probe
be left in contact with the surface for as short a time as needed to acquire a stable
measurement. While the transducer is in contact with a hot surface, it will begin to
heat up, and through thermal expansion and other effects, may begin to adversely
affect the accuracy of measurements.
Measuring laminated materials
Laminated materials are unique in that their density (and therefore sound-velocity)
may vary considerably from one piece to another. Some laminated materials may even
exhibit noticeable changes in sound-velocity across a single surface. The only way to
reliably measure such materials is by performing a calibration procedure on a sample
piece of known thickness. Ideally, this sample material should be a part of the same
piece being measured, or at least from the same lamination batch. By calibrating
to each test piece individually, the effects of variation of sound-velocity will be
minimized.
An additional important consideration when measuring laminates, is that any included
air gaps or pockets will cause an early reflection of the ultrasound beam. This effect
will be noticed as a sudden decrease in thickness in an otherwise regular surface.
While this may impede accurate measurement of total material thickness, it does
provide the user with positive indication of air gaps in the laminate.

The Transducer
The transducer is the “business end” of the TI-007DL. It transmits and receives ultra-
sonic sound waves that the TI-007DL uses to calculate the thickness of the material
being measured. The transducer connects to the TI-007DL via the attached cable, and
one coaxial connector.
The transducer must be used correctly in order for the TI-007DL to produce accurate,
reliable measurements. Below is a short description of the transducer, followed by
instructions for its use.
The photo below shows a typical single element delay line transducer. This delay line
is fastened to the transducer with a retainer ring. A drop of couplant is applied between
the delay line and transducer body. The transducer body contains one crystal element
that is responsible for conducting ultrasonic sound into and back from the material
being measured. When the transducer is placed against the material being measured, it
is the area directly beneath the delay line that is being measured.
When measuring, press against the top of the transducer with the thumb or index
finger to hold the transducer in place. Moderate pressure is sufficient, as it is only
necessary to keep the transducer stationary, and the delay line seated flat against the
surface of the material being measured.
Making Measurements
In order for the transducer to do its job, there must be no air gaps between the wear-
face and the surface of the material being measured. This is accomplished with the use
of a “coupling” fluid, commonly called “couplant”. This fluid serves to “couple”, or
transfer, the ultrasonic sound waves from the transducer, into the material, and back
again. Before attempting to make a measurement, a small amount of couplant should
be applied to the surface of the material being measured. Typically, a single droplet of
couplant is sufficient.
After applying couplant, press the transducer (wearface down) firmly against the area
to be measured. The Stability Indicator should have six or seven bars darkened, and a
number should appear in the display. If the TI-007DL has been set to the correct sound
velocity (see page 6), the number in the display will indicate the actual thickness of the
material directly beneath the transducer.
If the Stability Indicator has fewer than five bars darkened, or the numbers on the
display seem erratic, first check to make sure that there is an adequate film of couplant
beneath the transducer, and that the transducer is seated flat against the material. If

the condition persists, it may be necessary to select a different transducer (size or
frequency) for the material being measured. See page 15 for information on
Transducer selection.
While the transducer is in contact with the material that is being measured, the
TI-007DL will perform four measurements every second, updating its display as
it does so. When the transducer is removed from the surface, the display will hold
the last measurement made.
IMPORTANT
Occasionally, a small film of couplant will be drawn out between the transducer and
the surface as the transducer is removed. When this happens, the TI-007DL may per-
form a measurement through this couplant film, resulting in a measurement that is
larger or smaller than it should be. This phenomenon is obvious when one thickness
value is observed while the transducer is in place, and another value is observed after
the transducer is removed.
Condition and Preparation of Surfaces
In any ultrasonic measurement scenario, the shape and roughness of the test surface
are of paramount importance. Rough, uneven surfaces may limit the penetration of
ultrasound through the material, and result in unstable, and therefore unreliable, mea-
surements. The surface being measured should be clean, and free of any small particu-
late matter, rust, or scale. The presence of such obstructions will prevent the transducer
from seating properly against the surface. Often, a wire brush or scraper will be help-
ful in cleaning surfaces. In more extreme cases, rotary sanders or grinding wheels may
be used, though care must be taken to prevent surface gouging, which will inhibit
proper transducer coupling.
Extremely rough surfaces, such as the pebble-like finish of some cast iron, will prove
most difficult to measure. These kinds of surfaces act on the sound beam like frosted
glass on light:, the beam becomes diffused and scattered in all directions.
In addition to posing obstacles to measurement, rough surfaces contribute to excessive
wear of the transducer, particularly in situations where the transducer is “scrubbed”
along the surface.
Calibration
In order for the TI-007DL to make accurate measurements, it must be set to the correct
sound-velocity for the material being measured. Different types of material have
different inherent sound-velocities. For example, the velocity of sound through steel is
about 0.233 inches-per-microsecond, versus that of aluminum, which is about 0.248
inches-per-microsecond. If the tool is not set to the correct sound-velocity, all of the
measurements the tool makes will be erroneous by some fixed percentage. The one
point calibration is the simplest and most commonly used calibration procedure for
optimizing linearity over large ranges. The TI-007DL provides two simple methods
for setting the sound-velocity, described in the following pages
–15 –
6.0 TRANSDUCER SELECTION
The TI-007DL is inherently capable of performing measurements on a wide range of
materials, from various metals to glass and plastics. Different types of material, how-
ever, will require the use of different transducers. Choosing the correct transducer for a
job is critical to being able to easily perform accurate and reliable measurements. The
following paragraphs highlight the important properties of transducers, which should
be considered when selecting a transducer for a specific job.
Generally speaking, the best transducer for a job is one that sends sufficient ultrasonic
energy into the material being measured such that a strong, stable echo is received by
the TI-007DL. Several factors affect the strength of ultrasound as it travels. These are
outlined below:
Initial Signal Strength
The stronger a signal is to begin with, the stronger its return echo will be. Initial signal
strength is largely a factor of the size of the ultrasound emitter in the transducer. A
large emitting area will send more energy into the material being measured than a
small emitting area. Thus, a so-called “1/4-inch” transducer will emit a stronger signal
than a “1/8-inch” transducer.
Absorption and Scattering
As ultrasound travels through any material, it is partly absorbed. If the material
through which the sound travels has any grain structure, the sound waves will experi-
ence scattering. Both of these effects reduce the strength of the waves, and thus, the
TI-007DL’s ability to detect the returning echo.
Higher frequency ultrasound is absorbed and scattered more than ultrasound of a lower
frequency. While it may seem that using a lower frequency transducer might be better
in every instance, low frequencies are less directional than high frequencies.
Geometry of the Transducer
The physical constraints of the measuring environment sometimes determine a trans-
ducer’s suitability for a given job. Some transducers may simply be too large to be
used in tightly confined areas. Also, the surface area available for contacting with the
transducer may be limited, requiring the use of a transducer with a small cone tipped
delay line. Measuring on a curved surface, may require the use of a transducer with a
matching curved wearface.
Temperature of the Material
When it is necessary to measure on surfaces that are exceedingly hot, special
delay lines may be necessary. Additionally, care must be taken when performing
a “Calibration to Known Thickness” with a high temperature application. See
Appendix B for more information on measuring materials with a high temperatures.
Selection of the proper transducer is often a matter of tradeoffs between various
characteristics. It may be necessary to experiment with a variety of transducers
in order to find one that works well for a given job. ELECTROMATIC can provide
assistance in choosing a transducer, and offers a broad selection of transducers
for evaluation in specialized applications.

Calibration to a known thickness
NOTE: This procedure requires a sample piece of the specific material to be mea-
sured, the exact thickness of which is known, e.g. from having been measured by some
other means.
1. Make sure the TI-007DL is ON.
2. Apply couplant to the sample piece.
3. Press the transducer against the sample piece, making sure that the transducer sits
flat against the surface of the sample. The display should show some (probably
incorrect) thickness value, and the Stability Indicator should have nearly
all its bars on.
4. Having achieved a stable reading, remove the transducer. If the displayed thickness
changes from the value shown while the transducer was coupled, repeat step 3.
5. Press the CAL key. The IN (or MM) symbol should begin flashing.
6. Use the UP and DOWN arrow keys to adjust the displayed thickness up or down,
until it matches the thickness of the sample piece.
7. Press the CAL key again. The IN/µs (or M/s) symbols should begin flashing.
The TI-007DL is now displaying the sound velocity value it has calculated based on
the thickness value that was entered in step 6.
8. Press the CAL key once more to exit the calibration mode. The TI-007DL is now
ready to perform measurements.
Calibration to a known velocity
NOTE: This procedure requires that the operator know the sound-velocity of the mate-
rial to be measured. A table of common materials and their sound-velocities can be
found in Appendix C.
1. Make sure the TI-007DL is ON.
2. Press the CAL key to enter calibration mode. If the IN (or MM) symbol is flashing,
press the CAL key again, so that the IN/µs (or M/s) symbols are flashing.
3. Use the UP and DOWN arrow keys to adjust the displayed velocity up or down,
until it matches the sound-velocity of the material to be measured.
4. Press the CAL key once more to exit the calibration mode. The TI-007DL is now
ready to perform measurements.
NOTE: At any time during the calibration procedure (IN, MM, IN/µs, or M/s flashing
in the display), pressing the SCAN key will restore the tool to the factory default
sound-velocity for steel (0.233 IN/µs).
To achieve the most accurate measurements possible, it is generally advisable to
always calibrate the TI-007DL to a sample piece of known thickness. Material
composition (and thus, its sound-velocity) sometimes varies from lot to lot and from
manufacturer to manufacturer. Calibration to a sample of known thickness will ensure
that the tool is set as closely as possible to the sound velocity of the material to be
measured.
7. Press the UP/DOWN arrow keys to scroll to the flashing Prnt/F-05
(the file chosen), or LISt (tape printer) symbol.
8. Press the SEND key to print the contents of the file.
9. Press the MEM key at any time to exit the data logging functions and return to
measurement mode.

3.0 TI-007DL MODES AND FEATURES
The Back Light
The back light of the TI-007DL can be set to three different positions on/off/auto.
The following steps outline the procedure for changing the settings of the back light:
1. Press ON/OFF key to power up the TI-007DL.
2. Press the MODE key to activate features and settings.
3. Press the UP/DOWN arrow keys to scroll to the LItE symbol.
4. Press the SEND key to toggle the status of the back light on/off/auto.
5. Press the MODE key once again to return to measurement mode.
Scan Mode
While the TI-007DL excels at making single point measurements, it is sometimes
desirable to examine a larger region, searching for the thinnest point. The TI-007DL
includes a feature, called Scan Mode, which allows it to do just that.
In normal operation, the TI-007DL performs and displays four measurements every
second, which is quite adequate for single measurements. In Scan Mode, however, the
tool performs eight measurements every second, but does not display them. While the
transducer is in contact with the material being measured, the TI-007DL is keeping
track of the lowest measurement it finds. The transducer may be “scrubbed” across a
surface, and any brief interruptions in the signal will be ignored. When the transducer
loses contact with the surface for more than a second, the TI-007DL will display the
smallest measurement it found.
When the TI-007DL is in measurement mode, press the MODE key to activate the fea-
tures and settings. The display will begin flashing ALAr (alarm), followed by the sta-
tus - on/off. Use the UP and DOWN arrow keys to scroll to SCAn mode. Press the
SEND key to toggle scan mode on/off. While scanning, the display will show a mov-
ing series of dashes instead of a thickness value. When the transducer is removed from
the material being scanned, the TI-007DL will (after a brief pause) display the smallest
measurement it found.
Alarm Mode
The Alarm Mode feature of the TI-007DL allows the user to set an audible and visual
Hi /Lo parameter when taking measurements. If the measurement falls below or above
the Hi /Lo limits, set by the user, a red light will be illuminated on the front panel of
the gauge and an audible indication (beep) will sound. This improves the speed and
efficiency of the inspection process by eliminating constant viewing of the actual read-
ing displayed. The following procedure outlines how to enable and set up this feature:
Using the Beeper
1. Press ON/OFF key to power up the unit
2. Press MODE key to activate features and settings.
3. Press the UP and DOWN arrow keys to scroll to bEEP.
6. Press the UP/DOWN arrow keys to scroll to the flashing CLr/F-05 (the file
selected by the user) symbol.
7. Press the SEND key to select the clear file option. The symbol (CLr?) will be
displayed.
8. Press the CLR key to confirm and clear the contents of the entire file.
9. Press the MEM key, at any time, to exit the data logging functions and return
to measurement mode.
Clearing all Files
1. Press the ON/OFF key to power up the TI-007DL.
2. Immediately press the CLR key. CLr? will be displayed.
3. Press the CLR key once again to clear all files.
Sending All Files to a Computer
At the end of the inspection process, or end of the day, the user may require the
readings be transferred to a computer. The following steps outline this procedure:

5.0 RS232 SERIAL PORT & THE DATA LOGGER
The TI-007DL is equipped with an RS232 serial port. Using the accessory cable (part#
N-306-0010), the TI-007DL has the ability to connect to a computer, or external stor-
age device. The following section outlines the procedure for connecting the TI-007DL
to a computer, and how to collect data using any standard communications program:
Connecting To a Computer
1. Connect the accessory cable (part# N-306-0010) to the 2 pin jack located on the
bottom of the TI-007DL, and the 9 pin connector to a serial port on the computer.
2. Start the communications software that will be used to collect the measurements
(i.e., Microsoft Windows 3.1 -Terminal, or 95/98 - HyperTerminal).
3. Setup the communications software using the following parameters:
Data Bits - 8, Parity - None, Stop Bits - 1, Baud Rate 1200 (to print a report),
or 9600 to transfer data file.
Note: A report can be printed to a communications program (i.e. HyperTerminal),
or printed to a serial printer using 8.5" x 11" paper.
4. Set the communications software COMM port to the port number that the
TI-007DL is connected - direct comm1, comm 2, etc.
5. Proceed to the section USING THE DATA LOGGER.
Note: Communications software packages generally have the ability to capture the
screen data to a common text file. This text file, containing the measurements, can
then be imported into any common spreadsheet program (i.e. Excel, Quattro Pro,
Lotus123) for further reporting requirements.
Using The Data Logger
The TI-007DL is equipped with an on board data logging feature. This will prove to
be a valuable reporting tool for inspection purposes. It will increase efficiency by
reducing the time it takes to manually record the measurements during the inspection
process. The TI-007DL can then be connected to a computer or serial printer to save
and print the results of the inspection.
The TI-007DL has a storage capacity of 1000 measurements. The TI-007DL has
10 files consisting of 100 sequential storage locations in each file. The procedure
for using the data logger is outlined in the following steps:
1. Press ON/OFF key to power up the TI-007DL.
2. Press the MEM key to activate the data logger.
Note: The display will flash FILE / F-01 (or the last file used) symbol. Remember,
there are 10 files F-01 thru F-10.
3. Press the SEND key to enter file setup.
The current file will be displayed ( F-01, F-03, etc. )
4. Press the UP / DOWN arrow keys to scroll to the file (1-10) that will be used to
record the measurements.

4.0 MEASUREMENT MODES
The TI-007DL is equipped with four measurement mode options (echo-echo, interface-
echo, plastic, auto). In echo-echo mode, the gauge has the ability to read thin metals
down to .006 inches (.15 millimeters). The echo-echo mode also allows the user to
measure the thickness of metals that have been previously coated or painted on the sur-
face. This enables the user to determine the thickness of the metal without having to
remove the paint. In interface-echo mode, the gauge has the ability to read plastics and
thicker materials. The TI-007DL 's auto mode will automatically switch between
modes according to the different materials being measured. The following section out-
lines how to switch between measurement modes:
Measurement Modes
1. Press ON/OFF key to power up the TI-007DL .
2. Press the MODE key to activate features and settings.
3. Press the UP or DOWN arrow keys to scroll to PLAS.
4. Press the SEND key to toggle between the different measurement modes:
E-E (Echo-Echo), I-E (Interface-Echo), PLAS (Plastic), AutO (Auto).
5. Press the MODE key once again to return to measurement mode.
Differential Mode
In the Quality Control environment, it is sometimes necessary to know the difference
between a nominal (target) thickness value and an actual thickness value.This feature
is also included in the TI-007DL. With the Differential Mode enabled, the TI-007DL
will display the positive or negative difference from an entered nominal value.
The following steps outline the procedure for setting up this feature:
