The TKG100 is a base gauge offering a simple user
interface packaged in the same custom molded highdensity plastic case with rubber keypad as the other more
sophisticated models. This gauge offers reliable, accurate
thickness readings on mostly steel structures with access
to only one side.
The TKG150 contains all the same features of the
TKG100 plus:
50,000 (expandable to 100,000) reading
datalogger capacity with complete setup
tracking
Three pre-set files for linear, grid (row advance)
and grid (column advance)
Echo-to-Echo
B-scan
Probe Zero
When turning on the TKG100 or TKG150 (for the sake
of this manual, with the exception of the datalogger, Bscan, and Echo-to-Echo features, the two model
numbers are interchangeable for the basic operation and
calibration), the gauge does an automatic zeroing of the
transducer (after the user selects the transducer from the
list) thus eliminating the need for an on-block zero. The
TKG100 and TKG150 will electronically zero the
transducer upon power up and at a particular time during
normal operation. This feature ensures the transducer is
9
working in accordance with electronic zeroing
procedures. This feature is particularly important on high
temperature materials and when the transducer becomes
worn.
Important Notice: Please make sure the transducer
is not coupled to the test piece when the gauge is first
turned on and that there is no couplant on the end of
the transducer. The transducer should also be at room
temperature, clean without any noticeable wear.

3 Calibrating the Gauge
Calibrating is the process of adjusting the gauge for a
specific material and transducer before testing material to
make sure that all measurements are accurate. You must
always calibrate before measuring material for standard
accuracy.
To measure a thickness of unknown material you need to
know the velocity of the sound in the unknown material.
To find the velocity of the sound you can use one of the
following methods:
Velocity calibration only
Velocity and zero calibration
Zero calibration only
Delay line calibration
Velocity Calibration Only
If you are working with a test piece of known thickness
but unknown material, then you can calibrate the velocity
of the sound in the unknown material by measuring the
time of flight from main-bang to the first back echo. By
using the known thickness you can calculate velocity of
the sound for the unknown material.
To perform any calibration, first go to the measure mode
and press Menu/OK. Then select the Calibration option
from the Menu screen and press OK. The following
Calibration mode screen (or similar) should appear. To
21
exit the calibration screen without performing any
calibration, press OK. To proceed to the Velocity
calibration, follow the following instructions.
Cal screen for TKG100 non-datalogger version
While measuring the thicker step, select VEL by pressing
F3. After selecting VEL, you can take the transducer off
the test block. If the displayed measurement is different
than the known value of the step, use the up or down
arrow key to adjust the displayed value to the known
value of the step. Press OK to perform the calibration.
The unit will briefly display the calibrated velocity value
in the top of the screen and then return to measure
mode.
Velocity and Zero Calibration
If you have a test step block of known thicknesses but
unknown material, then you can calibrate the zero and
velocity of the sound in the unknown material by
measuring the time of flight from the main-bang to the
first back echo for thinner step and thicker step.
Extech Instruments .
22 TKG100_TKG150 Ultrasonic Thickness Gauge User Guide v2.8 11/13 22
To calibrate both: velocity and zero at the same time first
go to the Calibration mode as shown in Velocity
Calibration Only section. While measuring the thicker
step, select VEL by pressing F3. After selecting VEL you
can take the transducer off the test block. If the displayed
value is different than the known value of the step, adjust
the value by pressing up or down arrow keys and press
F1/CAL. Then while measuring the thinner step select
ZERO by pressing F2. After selecting ZERO you can
take the transducer off the test block. If measured value
is different than the known value of the step, adjust the
measured value by pressing up or down arrow key and
then press OK. The unit will briefly display the calibrated
zero value and then return to Measure mode. Note that
the order of Velocity and Zero calibration could be
reversed. If Velocity calibration is performed after Zero
calibration, the calibrated velocity value will be displayed
at the end of the calibration process.
Zero Calibration Only
If you have a test step block of known thickness and
known velocity of sound in the material, then you can
calibrate the zero by measuring the time of flight from
main-bang to the first back echo for the thinner step.
The calibrated zero is the calculated zero minus the
measured zero.
To accurately measure a thickness of unknown material
you need to know the velocity of the sound in the
unknown material and the errors introduced by the cable
23
and electronics. This is called delay line and zero
calibrated value for the transducer.
To perform a zero calibration, go to the Cal mode as
shown in Velocity Calibration Only section. Then while
measuring the thinner step, select ZERO by pressing F2.
After selecting ZERO, you can take the transducer off
the test block. If the displayed measurement is different
than the known value of the step, use the up or down
arrow key to adjust the displayed value to the known
value of the step. Press OK to perform the calibration.
The unit will briefly display the calibrated zero value in
the top of the screen and then return to measure mode.
Delay Line Calibration
Delay line calibration is done every time the thickness
gauge is powered on and a transducer is selected, or
when a different transducer is selected during normal
operation.
Delay line calibration is performed by measuring the
echo of the transducer itself when it is not placed on any
material and there is no couplant on the transducer
surface.
Under normal usage, the surface of the transducer wears
over time, which reduces sensitivity of the transducer.
When you power on any of the TKG series thickness
gauges and select a transducer, the gauge performs
automatic calculations and warns you (patent pending) if
Extech Instruments .
24 TKG100_TKG150 Ultrasonic Thickness Gauge User Guide v2.8 11/13 24
the sensitivity of the transducer is too low and whether
the transducer should be replaced.
Automatic Zero
To perform an Automatic Zero or Auto Zero, you must
first select a transducer option from the Transducer
selection screen and press the Menu/OK key.
To continue the Auto Zero, follow these steps:
1. Follow the instructions given on each display
screen; the first of which will prompt you to
wipe off any couplant from the transducer and
wait three seconds. The waiting time is shown
in the changing pie-clock graphic on the display
screen.
25
2. After three seconds the gauge automatically
begins to zero the transducer. During the delay
line calibration a screen appears displaying the
message “Performing Auto Zero”.
3. A warning message will appear on the display
screen if the delay line is below the acceptable
limit for accurate thickness measurements. You
will need to replace the transducer or select the
F1 key to acknowledge the warning message
and continue using the same transducer, which
may have a worn surface.
4. After three seconds or after acknowledging the
warning message, the display shows the
instrument parameters for 3 seconds before
going to
Measurement
mode.

Understanding a LOS Reading
LOS (Loss of Signal) occurs when the gauge is not
making a valid reading. This can happen for a variety of
reasons, including the ones in the list below:
Extech Instruments .
34 TKG100_TKG150 Ultrasonic Thickness Gauge User Guide v2.8 11/13 34
Not enough couplant
Surface is too rough or rusty
Low Transducer sensitivity
Temperature is too high
Dis-bond exists between the coating and the
steel
In the event you try to save a reading in LOS with the
TKG150, the Notes screen will automatically appear so
that a reason is given for saving an LOS. You can scroll
to the appropriate note and press the soft Save key.
Using the Hold Option
If a LOS occurs, the gauge can continue to display the
last measured thickness by “holding” or freezing the
measurement.
35
Using the Fast Option
The Fast option is available by accessing the main
MENU, selecting MEASUREMENTS, and then
selecting FAST from the list.
To select the Fast option, follow these steps:
1. Use the up and down arrow keys to highlight

2. The following parameters are available:
3. Use the up and down arrow keys to select the
desired parameter and press the OK key.
4. Press F1 Back key to return to the
Measurement mode.
Extech Instruments .
36 TKG100_TKG150 Ultrasonic Thickness Gauge User Guide v2.8 11/13 36
In the Measurement the selected Fast option setting is
displayed similar to the screen below:
Helpful Hint: When using the FASTMIN mode, if you
press the F2 key “Freeze” prior to LOS, the gauge will
display the last minimum prior to the LOS so that the
actual couplant on the end of the transducer is not
registered as a legitimate minimum reading.
The parameters that you select in the Fast option are
shown as follows in Measure mode:
FAST when On is selected
FASTMIN when Min is selected
FASTMAX when Max is selected
<BLANK> when Off is selected
The Fast option allows you to select fast updates of
measurements at 20 Hz compared to 4 Hz. If you select
the FastMax option, the LOS will display the LAST
MAX measured value, or if you select the FastMin
parameter the LOS will display the LAST MIN measured
37
value. If you select the On parameter from the Fast
option, the LOS will work normally and not show the
measured reading.
The screens below reflect different parameters selected
from the Fast option. For example, the top screen shows
the FASTMAX with LAST MAX measurement on LOS,
and the bottom screen shows the FASTMIN with LAST
MIN measurement on LOS.
Note: The LOS flag indicates the LAST MAX or the
LAST MIN value and is shown based on the FastMax or
FastMin setting.
Extech Instruments .
38 TKG100_TKG150 Ultrasonic Thickness Gauge User Guide v2.8 11/13 38
To reset the tracking of LAST MAX and LAST MIN
measured value press the OK (Menu) key.
Using the Gain Option (TKG150 only)
Gain refers to an increase in signal power (echo height)
and is typically measured in decibels (dBs). The Gain
function is useful for setting a reference level where by
making it easier to add or subtract gain. There are three
Gain options, which include: LOW dB, STD dB & HI
dB. The Gain selection is available from the
Measurements mode screen in the Main MENU.
1. Use the up and down arrow keys in the
Measurements screen to highlight the Gain
option.
The following Gain parameters are available:
STD (standard), LO, and HIGH

Using the Diff Option
There are 3 Diff options:
ABSOLUTE: Absolute, where the gauge will
display a thickness value as an absolute number.
For example, diff abs = 0.500” and the real
thickness is 1.000 inch, the display will show
diff abs 0.500. If the real value is 0.300, the
gauge will display, -0.200”
PERCENT: When this mode is on, the
displayed value will be listed as a percentage of
the value entered into as the diff. For Example,
if the operator set the diff to percentage at
0.500”, a reading of 0.250” will result in 50%
OFF: Diff Option off.
In the Measure mode screen, highlight the DIFF option
and select the desired option using the right/left arrow
keys. Press F1 to exit Measurement mode and save

sounds, display flashes, vibrations (if on) and illuminating
keypad. There are several alarms options, which include:
Alarm On/Off: Sets the audible alarm either on
or off.
Low Alarm: Audible alarm will occur and
display will flash when the displayed reading is
less than the low alarm reference value.
High Alarm: Audible alarm will occur when the
displayed reading is higher than the high alarm
reference value.
High_Low Alarm: Audible alarm will occur and
display will flash when the displayed reading is
less than the low alarm or greater than the High
alarm reference value.
Low Alarm/Vibra (TKG150 only): Vibration
alarm will occur and display will flash when the
displayed reading is less than the low alarm
reference value.
High Alarm/Vibra (TKG150 only): Vibration
alarm will occur and display will flash when the
41
displayed reading is higher than the high alarm
reference value.
High_Low Alarm/Vibra (TKG150 only):
Audible alarm will occur and display will flash
as well as vibrate when the displayed reading is
less than the low alarm or greater than the High
alarm reference value.
The Alarm option is available from the Measurements
screen list.
1. Use the up and down arrow keys to highlight
the Alarm option and press the OK key (or you
can use Quick Access mode by using the right
or left keys once Alarm is highlighted). For the
TKG100 model you can also press the F1
(Alarm) key to go directly to the Alarm option

2. Use the up and down arrow keys to select the
desired alarm type and then press the OK key.
The following screen below appears (screens
will differ slightly based on alarm type
selection). Use the up and down arrow keys to
select the high, low, or percent parameters and
then use the left/right arrow keys to change the
Alarm limits. Press the OK key to continue.
Note: The Low Alarm limit will not go beyond the High
Alarm limit.
3. When you are finished adjusting the setting,
press the F1 key to return to Measure mode.
43
Visual and Audible Alarm
The Visual Alarm conditions can be viewed from either a
red, yellow or green LED that light up under the F1, F2,
or F3 keys on the keypad.
As an example, when using the 5 step English test block
with thicknesses of 0.100, 0.200, 0.300, 0.400 and 0.500
inches, if you enter alarm high-low you will first need to
enter the high value. Enter 0.500 and press enter. Next
you will need to enter the low value of 0.100 in. The
display will ask you to enter the percent reading of the
high low. The gauge will default to 20% (this can be
changed with the up or down keys), so any reading within
20% of the high value (approaching high, between 0.400
and 0.499 as 0.400 is within the 20% range of 0.500.) will
result in the yellow keypad lighting up. Also, any reading
above the low value of 0.101 and 0.120 will result in the
yellow F2 keypad lighting up as you are approaching the
minimum
So, in Alarm mode, choosing a non-zero percent value
provides the user with warning for readings approaching
the selected percent value of the high or low limits. For
example, if the alarm value is 0.100" and 20% is entered
as the “percent value”, reading from 0.101" to 0.120" will
result in the F2 “yellow” key being illuminated. Also,
reading less than 0.100" will result in the F1 key “Red”
being illuminated and greater than 0.120" will result in
the F3 “Green” key being illuminated.

Extech Instruments .
58 TKG100_TKG150 Ultrasonic Thickness Gauge User Guide v2.8 11/13 58
Managing the Datalogger File System
The TKG150 supports the following two files types:
Linear file
: Consists of ID# from 0001 to
5000. The extended memory option consists of
ID# from 1 to 500000.
Grid file
: Consists of ID# as COLUMN and
ROW. The COLUMN is single or double digit
capital alpha character from A to Z and AA to
ZZ. The ROW is a four digit number based on
the 5000 / COLUMN.
For example, when you create a new GRID file with
END COLUMN = C, then the maximum ROW you can
slew up to is limited to 1666 calculated by the instrument
as follows:
The total storage space per file is 5000 readings.
For Columns ending at C, this means 3 columns
are required and the maximum Row allowed is
limited to 5000 / 3 = 1666.
If you create a new GRID file with END COLUMN =
Z, then the maximum ROW you can slew up to is limited
to 5000/26 = 192.
If you create a new GRID file with END COLUMN =
AF, then the maximum ROW you can slew up to is
limited to 5000/(26 for A to Z + 6 for AA to AF) = 156
the grids are created as shown below:
59
A,1 to A,156 then
B,1 to B,156 then
:
Z,1 to Z,156 then
AA,1 to AA,156 then
AB,1 to AB,156 then
:
AF,1 to AF,156
If a new GRID file with END COLUMN = ZZ, then
the maximum ROW you can slew up to is limited to
5000/(26 for A to Z + 26*26 for AA to ZZ) = 7.
A,1 to A,7 then
B,1 to B,7 then
:
Z,1 to Z,7 then
AA,1 to AA,7 then
AB,1 to AB,7 then
:
AZ,1 to AZ,7 then
BA,1 to BA,7 then
BB,1 to BB,7 then
:
:
ZZ,1 to ZZ,7
Extech Instruments .
60 TKG100_TKG150 Ultrasonic Thickness Gauge User Guide v2.8 11/13 60
Note that there are two different types of Grid files:
ROWINC and COLINC. The above two examples show
how the ID locations are incremented in ROWINC type
file only. Here the Row value is incremented first, while
updating ID location. Whereas, in a COLINC type file,
Column value is incremented first.
So for a COLINC file with END COLUMN value AF,
the ID locations will increment as follows:
A,1 to AF,1 then
A,2 to AF,2 then
.
.
A,156 to AF,156
A COLINC file with END COLUMN value ZZ will
have ID increments as follows:
A,1 to ZZ,1 then
A,2 to ZZ,2 then
.
A,7 to ZZ,7

B-Scan (TKG150 only)
The B-Scan represents a cross sectional view on the test
piece. The simplest example is to show a 5 step test
block. To turn on the B-Scan on the TKG150, press
MENU/OK, scroll to MEASUREMENTS and press
OK, select B-scan and press MENU/OK. First enter the
maximum thickness you expect to scan using the up,
down, left and right keys, then turn on the B-Scan
scrolling down and right arrow (left arrow for off). Press
F3 in lefty or F1 in righty mode when done. The bottom
of the display will read SAVE, START or STOP and
CLEAR. To Start a B-Scan, couple to a test block and
press F2 [START]. If you uncouple the transducer, BScan will stop due to LOS. If you press F2 [STOP] the
minimum thickness will be displayed in the center of the
screen while a vertical cursor allows you to review
readings. During review the thickness value is updated in
the top right of the display. To save all the readings, press
F1 [SAVE]. The amount of saved readings up to the file
size of 5,000 readings or what was pre-determined in the
current file (See Datalogging) set up. Here is a picture of
the B-Scan on a test block.
