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.

Electromatic maintains a customer support resource in order to assist users with

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 sound­velocity 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 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 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 measure­ment, 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 auto­matically to the right, allowing values up to 99.99 millime­ters 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 — APPLICAT ION 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 mate­rials 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 materi­al 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.
