About the TKG Series

The TKG100 and TKG150 are portable, digital, handheld thickness gauges. The TKG series of ultrasonic thickness gauges are specifically designed to measure the remaining wall thickness of primarily steel structures.

 Vibralarm (vibrates gauge below/above minimum/maximum thickness value)

 Illuminating keypad for easy to view go-no go thickness values (patent pending)

 Automatic transducer replacement intelligence built in (patent pending)

 Unique, programmable left-hand/right-hand operation (patent pending)

 Up to 200 hour battery life with 2 AA batteries

 Small, easy to hold, ergonomic, custom molded, durable case with rubber keypad

 Automatic zero capability

 Gain boost

7

Extech Instruments

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


8

.

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


20

.

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.

21

Extech Instruments

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


22

.

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

23

Extech Instruments 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.


24

.

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.

33

Extech Instruments

 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

35

Extech Instruments

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

FASTMIN

FASTMAX when when when

On is selected

Min

Max

is selected

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


36

.

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.

37

Extech Instruments

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

38

.

In the Measure mode screen the Gain option that you select is displayed on the center/right side of the display.

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 settings.

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.

6 Using the Echo-to-Echo Option (TKG150 only)

The Echo-to-Echo option allows you to make measurements between two consecutive back-wall echoes. Therefore, a good usage of the Echo-to-Echo option is for measuring through coatings to measure only the true metal thickness. There are two Echo-to-Echo options you can select, which are as follows:

 Echo-to-Echo On: Enables the Echo-to-Echo function

 Echo-to-Echo Off: Disables the Echo-to-Echo function

In the Measurements mode screen in the Main menu, highlight the E-TO-E option and select the desired option using the right/left arrow keys. Press F1 to exit

Measurement mode and save settings and F1 again to get back to the measurement mode.

57

Extech Instruments

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:


58

.

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

59

Extech Instruments

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
