Sound Velocity m/s

The Check•Line model TI-CMXDLP is an ultrasonic thickness gauge that measures

with extreme versatility. It has the ability to measure simultaneously measure coatings and material thicknesses while maintaining the ability to locate pits, aws and defects in the material. Based on the same operating principles as SONAR, the TI-CMXDLP is capable of measuring the thickness of various materials with accuracy as high as ± 0.001 inches, or ± 0.01 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.

1.1 Disclaimer

Inherent in ultrasonic thickness measurement is the possibility that the instrument will use the second rather than the rst echo from the back surface of the material being measured. This may result in a thickness reading that is TWICE what it should be. Responsibility for proper use of the instrument and recognition of this phenomenon rest solely with the user of the instrument. Other errors may occur from measuring coated materials where the coating is insufciently bonded to the material surface. Irregular and inaccurate readings may result. Again, the user is responsible for proper use and interpretation of the measurements acquired.

13.0 USING THE UTILITY SOFTWARE

2.0 QUICK STARTUP GUIDE

13.1 Computer System Requirements

Datacomm will run on many different operating systems: Windows 98 (1st or 2nd edition), Windows NT 4.0 with Service Pack 5, Windows ME, Windows XP, Windows2000 Professional, Windows 2000 Server, or Windows 2000 Advanced Server operating systems running on Intel or AMD hardware. A Pentium 166MHz or faster processor with at least 32 megabytes of physical RAM is required. You should have 40 megabytes of free disk space before attempting to install Datacomm. Datacomm requires an available communications port in order to transfer data to and from the TI-CMXDLP. Datacomm supports COM1, COM2, COM3, and COM4. USB to Serial Converter. Some newer laptop computers do not have standard serial ports. In this case it is possible to use a USB to Serial converter. If a serial to USB cable is needed, contact Electromatic.

13.2 Installing Datacomm

Datacomm comes on a CD-ROM with an automatic installer program. Place the CD in your computer’s CD tray and close the door. Open the CD-ROM by double clicking on the My Computer ICON, then double click on the CD. Finally, double click on the SETUP icon to begin the installation. Refer to the help section in Datacomm software for the complete operating manual,setup, and operation.

13.3 Using the XFER menu (TI-CMXDLP)

The XFER menu of the TI-CMXDLP will be used in conjunction with the Datacomm PC software. The steps below outline the procedure for accessing the XFER menu and basic operation as follows:

1. Press the MENU key once to activate the menu items tab. Press the MENU key multiple times to tab right, and the ESC key multiple times to tab left,until the XFER menu is highlighted and displaying the submenu items.

2. Use the UP and DOWN arrow keys to scroll through the sub menu items until the desire option is highlighted.

3. Press the ENTER key to activate the option selected.

4. Once the Backup or Restore function has been completed, press the MEAS key once to return to the menu items, or twice to return to the measurement mode.

Turn the TI-CMXDLP on and off using the switch located on the bottom right corner of the keypad. When TI-CMXDLP is initially turned on, a ash logo and blinking lights will be displayed, followed by the identity of the transducer (probe) currently plugged into the gauge. The TI-CMXDLP is equipped with an “Auto Probe Recognition” feature that attempts to identify special transducers. If the TI-CMXDLP doesn’t nd a transducer equipped with this feature, the user will be see a list of transducers and will need to select a specic transducer type. The following sections outline each scenario.

NOTE: This section is primarily written as a basic startup guide only.

2.1 TI-CMXDLP Overview

The TI-CMXDLP has great features and tools that will be a benet for the variety of applications you face on a continual basis. Let’s have a brief look at the screens you’ll be looking at most often:

A. Repeatability/Stability Indicator: This is used in

conjunction with the digital thickness values displayed. When all the vertical bars are fully illuminated and the last digit on the digital thickness value is stable, the TI-CMXDLP is reliably measuring the same value 3 to 200 times per second, depending on which measurement mode and features are enabled.

B. Battery Icon: Indicates amount o f battery life remaining.

C. Velocity: The material velocity value the TI-CMXDLP is currently using or calibrated for. It can be set to display in English or Metric units.

D. Feature Status Bar: Indicates the features currently enabled and in use in the following order:

1. Measurement Mode 3. High-Speed Scan Mode 5. Gain Setting

2. Differential Mode 4. Alarm Mode

– 100 –

– 5 –

E. Digital Material Thickness Value: Extra large font size for viewing ease.

F. Scan Bar: Another view of material thickness in a deection style horizontal bar.

This visual tool enables the user the ability to see thickness changes during high speed scans from aws and pits.

G. Units: The current measurement units being used (English, Metric)

H. Digital Material Thickness Value: Smaller font size when the B-Scan display

view is enabled.

I. Coating Thickness Value: Displays the actual thickness of any coating adhered to a metallic material surface (PECT Mode), or a coating adhered to anon-metallic surface (CT Mode).

J. Minimum Material Thickness: Part of the Alarm feature. Displays the minimum thickness value found during a scan.

K. Maximum Material Thickness: Part of the Alarm feature. Displays the maximum thickness value found during a scan.

L. B-Scan Display: Cross section view of the material. Provides a graphical view of the opposite/blind surface (i.e. inside pipe wall surface), to give some idea of the condition, or integrity of the material being tested.

M. RF A-Scan Display: The actual sound wave reection returned from the detection of the opposite surface of the material being measured. In this view, the entire sine wave is displayed, showing both the positive and negative half cycles from the detection/reection. This view is commonly used to “see the big picture” and make ne adjustments to the scope settings, prior to selecting another view option.

N. Hot Menu items: Items in this menu section are the most commonly adjusted features. They can be displayed and scrolled by pressing the MEAS key at anytime. The ESC key is used in conjunction with MEAS key to reverse the direction scrolled.

O. Reference Note: When the “hot menu” items are displayed/activated, the base material thickness value shown at reference point “O”. However, when the “hot menu” items have been deactivated, the current base material velocity value is displayed, as shown in reference point “P”. When the “hot menus” are deactivated, the entire “hot menu” section becomes a multiple measurement display area, allowing the user to simultaneously view: base material, coating,and base material minimum/maximum thickness values dynamically, as shown in reference point “R”

P. Reference Note: Please refer to “O”, for a detailed explanation.

Q. RECT A-Scan Display: The actual sound wave reection that is returned from the

detection of the opposite surface of the material being measured. In this view, only half of the sine wave is being displayed (positive or negative). This view is comonly used as a “aw detection” mode, once the user made all the necessary adjustments using the RF mode (refer to M).

12.5 Using the Default Setup

The default setup feature was added to the TI-CMXDLP to use, as a last resort, if there are no setups stored in the gauge –factory or otherwise. The only time this might possibly occur is if the setup le in the TI-CMXDLP was somehow corrupted, and the user does not have access to a computer to re-load the factory setups back into the TI-CMXDLP. This gives the user the ability to load and modify a basic setup as follows:

NOTE: The default le contains no probe zero data. Therefore, a zero must be performed after loading. Also, the default setup can be loaded when using the aw mode feature, to eliminate the probe zero delay value, and start at the initial pulse or zero.

1. Press the MENU key once to activate the menu items tab. Press the MENU key multiple times to tab right and the ESC key multiple times to tab left until the SETUP menu is highlighted and displaying the submenu items.

2. Use the UP and DOWN arrow keys to scroll through the sub menu items until DEFAULT SETUP is highlighted.

12.6 Selecting a Language

The TI-CMXDLP is equipped with a language option. Currently, the only languages supported are English, Spanish, and German.

2. Use the UP and DOWN arrow keys to scroll through the sub menu items until LANGUAGE is highlighted.

3. Press the LEFT and RIGHT arrow keys to toggle the language options.

4. Once the desired language is displayed, press the MEAS key to return to the measurement screen.

7. Press the OK key to return to the Save Setup

Parameters List Box.

8. If both parameters will be edited, repeat steps 4 – 7.

9. Use the UP and DOWN arrow keys to scroll to and highlight SAVE SETUP.

10. Press the ENTER key to activate the Setup List Box.11) Use the UP and DOWN arrow keys to scroll through the setups until the target location to save the Setup is highlighted.

12. Press the OK key to activate the conrmation screen.

13. Press the OK key to save the Setup, or ESC to cancel saving the Setup.

14. Finally, press the MEAS key to return to the measurement screen.

NOTE: The Name and Comments of the Setup can be edited at any time by simply repeating the Save Setup routine described above. Therefore, the Save Setup function can also be considered an Edit Function.

12.4 Deleting a Saved Setup

This option allows a user to delete setup les that were previously saved and no longer needed. It’s a simple feature to allow the user to do a bit of “house cleaning”.

2. Use the UP and DOWN arrow keys to scroll through the sub menu items until DELETE is highlighted.

3. Press the ENTER key to display the Setups List.

4. Press the UP and DOWN arrow keys to scroll to the Setup Name.

5. When the Setup Name is highlighted, press the ENTER key to display the conrmation screen.

6. Press the OK key to delete the Setup File.

7. Finally, press the MEAS key to return to the measurement screen.

2.2 Auto Probe Recognition

When the TI-CMXDLP is initially powered up, the gauge will automatically check to see if the transducer plugged into the gauge can be recognized. The steps that follow assume the TI-CMXDLP recognized the probe type:

1. Press the OK key once to use the identied probe, or ESC to display a list of optional transducers.

NOTE: If the TI-CMXDLP recognizes a specic transducer, the user should always select OK to use the identied probe. The only time an alternative probe should be selected from a list is if the user switched probes following initial power up and recognition

2. Assuming the TI-CMXDLP recognized the probe and the OK key was pressed, the TI-CMXDLP will advance to a Zero Probe menu. If the transducer was identied as a special transducer capable of measuring coating thickness, a menu will be displayed giving the user the ability to toggle the coating thickness display on/off as follows:

3. Press the UP and DOWN arrow keys to toggle the coating option on/off.

4. Wipe all couplant from the transducer face and advance to the Probe Zero & Calibration section.

2.3 Selecting the Transducer Type

If the TI-CMXDLP does not identify a specic transducer type on initial power up, the user will be required to select a type from a predened list of types by diameter and frequency. By selecting a transducer type from a predened list, the TI-CMXDLP can recall specic properties about the transducer.

NOTE: Once the transducer has been selected, the TI-CMXDLP will store and recall this transducer type every time the TI-CMXDLP is powered on/off. The type will only change if the user physically selects another transducer type from the list, or selects a previously saved setup. However, the TI-CMXDLP will continue to take you through these steps each time the gauge is powered up. You’ll notice that the probe type previously selected will be highlighted every time the probe type screen is displayed. Use the following steps to select your transducer type:

– 98 –

– 7 –

1. Press the OK or ESC keys to display the factory list of transducer types

(by diameter and frequency).

2. Press the UP and DOWN arrow keys to scroll through the transducer list until the

appropriate type is highlighted.

3. Press the ENTER key to select the transducer type and display overwrite existing

probe screen.

4. Press the OK key to overwrite the existing probe type with the newly selected probe

type. The zero probe screen will be displayed. Proceed to the zero probe section that follows.

2.4 Probe Zero & Calibration

The next steps are to perform a probe zero and calibrate the TI-CMXDLP to the material and transducer being used. If the sound velocity is unknown, the TI-CMXDLP can be calibrated to a known thickness sample. This demo will briey explain both of the set techniques. The TI-CMXDLP is equipped with two zero options:

1. Off Block Zero (Automatic Probe Zero): When this feature is enabled the TI-CMXDLP will do an electronic zero automatically, eliminating the need for a zero disk or block.

2. On Block Zero (Manual Probe Zero): When this feature is enabled the transducer must be placed on the Probe Zero Disk (battery cover located on the top of the unit.

NOTE: Transducers of the same type will have very slight mechanical and electrical variations. If it’s discovered that the linearity is off following an initial auto probe zero and extreme accuracy is required, a manual zero should be performed followed by an auto zero. This will adjust and eliminate any error. This is only required if it’s discovered the transducer is non-linear following an initial auto probe zero. The procedures are outlined as follows:

4. Use the UP and DOWN arrow keys to scroll through

the setups until the target setup is highlighted.

5. Press the ENTER key to activate the conrmation

screen.

6. Press the OK key to load the setup from memory.

7. Press the MEAS key to return to the measure screen.1

12.3 Saving a Setup

Once the TI-CMXDLP parameters and features have be adjusted for an application, the user may elect to save these setting to a specic setup location for future use. This can potentially save time and reduce error between users. It is sometimes necessary to rename a previously saved setup, or add additional comments about a particular setup. The setup name may have been entered incorrectly, or the user needs to use the setup for a completely different project. An inspector’s name or other comments about the project may also be required for additional documentation purposes. The following procedures outline the necessary steps for saving and editing a setup:

2. Use the UP and DOWN arrow keys to scroll through the sub menu items until SAVE is highlighted.

3. Press the ENTER key to display the Save Setup Parameters List Box.

4. Press the UP and DOWN arrow keys to scroll the Name and Note parameters.

5. When the parameter to edit is highlighted, press the ENTER key to activate the Alpha Edit Box.

6. Use the UP, DOWN, LEFT, and RIGHT arrow keys to scroll through the characters, the ENTER key to select characters, and the CLR key to backspace through the characters, until the Name or Note elds have been edited.

12.0 SETUPS – CREATE, STORE, EDIT, & RECALL

12.1 Introduction to Setups

Often times, users are faced with a variety of tasks and applications that are sometimes similar, but often times very different. With a standard thickness gauge,the user would have to recalibrate for each individual application respectively. With all the features of the TI-CMXDLP, the number of potential applications also increases based on ability alone. This is primarily in reference to the addition of those very difcult applications, where a standard thickness gauge would not be feasible, or capable of accomplishing the tasks. The increased number of features and parameters also adds to the overall setup time, or amount of time to set up marginal applications with perfection and understanding. Because of the additional time involved, the TI-CMXDLP has been equipped with the ability to save these setups to memory and be recalled at any time. The TI-CMXDLP can store up to 64 custom setups. These setups can be bidirectionally transferred to and from a PC. Therefore, the user can save as many setups as necessary for all their individual applications requirements. This saves a great deal of time and knowledge for future inspections of the same job or project. This feature also eliminates error between two or more users during the setup and calibration process.

12.2 Opening a Setup

The TI-CMXDLP is loaded with a number of setups from the factory. These setups can be opened, edited, and saved to any one of 64 setup locations. If a factory setup is written over, the user can simply reload the default factory setups at anytime using the utility software included with the TI-CMXDLP. The factory setups are general setups Only. However, they may serve as an excellent starting point, requiring only minor adjustments to work for custom applications. It is recommended that user customized setups be saved to an empty location, and save the factory setups for the purpose of a general starting point. The following procedures outline how to open factory and custom setups:

2. Use the UP and DOWN arrow keys to scroll through the sub menu items until OPEN is highlighted.

3. Press the ENTER key to display the Setup List Box.

Performing An Auto Zero (Off Block)

1. Be sure all couplant has been removed from the face of the transducer.

2. Press the OK key to perform the automatic probe zero, or ESC key to cancel the zero operation.

3. The screens illustrated will be briey displayed followed by the main measurement screen. The TI-CMXDLP is ready to be calibrated.

Performing a Manual Probe Zero (On Block)

NOTE: When the zero probe option is set to manual, the Probe Zero Disk (battery cap) located on the top of the gauge, will be used as a zero standard and the warning screen illustrated above will be displayed.

1. Press the OK or ESC keys to enter the main measurement screen and begin the manual zero process.

2. Apply a drop of couplant on the transducer and place the transducer in steady contact with the Probe Zero Disk, and obtain a steady reading.

3. Press the MENU key once to activate the menu items tab. Press the MENU key multiple times to tab right and the ESC key multiple times to tab left until the PRB menu is highlighted and displaying the submenu items.

4. Press the UP and DOWN arrow keys to scroll through the sub menu items until ZERO PROBE is highlighted.

5. Press the ENTER key to display the

conrmation screen.

6. If a coating transducer was identied

use the UP and DOWN arrow keys to toggle coating on/off.

7. Press the OK key to complete the probe zero function, or ESC key to cancel the Probe Zero function.

8. Remove the transducer from the Probe Zero Disk, and proceed to the calibration section.

NOTE: The value that is displayed will change depending on the current velocity setting in the TI-CMXDLP. Disregard the number that is displayed. It is not important. What is important is accurately performing the steps outlined above to insure reliability of the probe zero calculation.

One Point Material Calibration

For the purposes of this quick start section, we’ll only be covering the most common one point calibration option to determine the sound velocity of the test material. It would be very handy to carry a set of mechanical calipers to use in conjunction with the TI-CMXDLP for calibration in the eld.

Using a Known Thickness

NOTE: Be sure that the probe zero procedure has been performed prior to performing this calibration procedure.

1. Physically measure an exact sample of the material or a location directly on the material to be measured using a set of calipers or a digital micrometer.

2. Apply a drop of couplant on the transducer and place the transducer in steady contact with the sample or actual test material. Be sure that the reading is stable and the repeatability indicator, in the top left corner of the display, is fully lit and stable. Press the MENU key once to activate the menu items tab. Press the MENU key multiple times to tab right and the ESC key multiple times to tab left until the CAL menu is highlighted and displaying the submenu items.

3. Use the UP and DOWN arrow keys to scroll through the sub menu items until MATL 1PT is highlighted.

2. Use the UP and DOWN arrow keys to scroll through the sub menu items until CLOSE is highlighted.

3. Press the ENTER key to close the active le.

NOTE: Following the keypress, the CLOSE text will be grayed out indicating the le has been close and is no longer active.

11.7 Changing the Active File - Open

The user may have transferred grid/ seq templates from a PC to the TI-CMXDLP, or setup grids/seq using the TI-CMXDLP at an earlier time. The name of the currently active le is always displayed at the top of the Grid/ Seq Box in measurement mode (refer to photo below). It’s not only important to recognize what le is currently active, but also be able to change the active le at any time. The following procedures outline this process:

1. Press the MENU key once to activate the menu items tab. Press the MENU key multiple times to tab right and the ESC key multiple times to tab left until the DATA menu is highlighted and displaying the submenu items.

2. Use the UP and DOWN arrow keys to scroll through the sub menu items until OPEN is highlighted.

3. Press the ENTER key to display the Grid/Seq List Box.

4. Use the UP and DOWN arrow keys to scroll through the grids until the target grid is highlighted.

5. Press the ENTER key to activate the conrmation screen.

6. Press the OK key to load the le from memory.

7. Press the MEAS key to return to the measure screen.

11.8 Closing an active File - Close

A user might not have a current requirement to store measurements, but a le is currently open or active and needs to be closed. The following procedures outline how to close an open or active le :

In order to account for very slight electronic differences in transducers of the same type, frequency, and diameter, the TI-CMXDLP has been equipped with a “zero coating” feature. This enables the TI-CMXDLP to obtain very accurate readings on coatings, eliminating potential errors incurred from slight differences in the manufacturing processes. The procedure is outlined below:

Performing A Coating Zero

1. Press the MULTI MODE key once to activate the

measurement mode options.

2. Use the UP and DOWN arrow keys to scroll through

the sub menu items until Coating Only (CT) mode is highlighted.

3. Press the ENTER key to select the measurement mode

and return to the measurement screen.

4. Apply a drop of couplant on the transducer and place the transducer in steady contact with the Probe Zero Disk (battery cover) and obtain a steady reading.

NOTE: The coating measurement displayed will potentially be a value greater or less than 0.

5. Press the MENU key once to activate the menu items tab. Press the MENU key multiple times to tab right and the ESC key multiple times to tab left until the PRB menu is highlighted and displaying the submenu items.

6. Use the UP and DOWN arrow keys to scroll through the sub menu items until ZERO COATING is highlighted.

7. Press the ENTER key to display the conrmation screen.

8. Press the OK key to zero the coating and return to the PRB menu, or ESC to cancel the coating zero process.

9. Press the MULTI MODE key once to activate the measurement mode options.

10. Use the UP and DOWN arrow keys to scroll through the sub menu items until Coating On (PECT) is highlighted

11. Press the ENTER key to select the measurement mode and return to the measurement screen, and begin taking readings.

2.6 Coating Calibration

The TI-CMXDLP has been preset to a default coating velocity of 0.0850 in/sec (2159m/sec). This will be very close to the most common coating material velocities used in the eld. If the velocity of the coating is known, and different than the above default setting, the user can simply enter the coating velocity into the TI-CMXDLP. However, if the velocity is unknown, the TI-CMXDLP can also be calibrated to a specic coating sample/type using the 1pt calibration option in PECT (pulse-echo coating)mode, or a two point calibration is CT (coating only) mode. For the purpose of this quick start section only the 1pt option PECT (pulse-echo coating) mode will be covered. Refer to the calibration section of the manual for a complete explanation on the coating calibration options. The following steps below outline the necessary steps to either set the velocity of the coating, or perform a one point calibration to calculate the coating velocity:

Known Coating Velocity

If the coating velocity is known, the user may wish to simply enter the velocity number into the TI-CMXDLP, rather than have the TI-CMXDLP calculate the velocity value using a known thickness on a coating sample. The steps for entering the velocity are outlined below:

1. Press the MENU key once to activate the menu items tab. Press the MENU key multiple times to tab right and the ESC key multiple times to tab left until the CAL menu is highlighted and displaying the submenu items.

2. Use the UP and DOWN arrow keys to scroll through the sub menu items until COATING VEL is highlighted.

3. Press the ENTER key to display the Digits Edit Box.

4. Press the UP and DOWN arrow keys to scroll the highlighted value.

5. Press the LEFT and RIGHT arrow keys to scroll the digit locations.

6. Repeat steps 4 & 5 until the velocity number is correctly displayed.

7. Press the OK key to set the coating velocity and return to the menu screen,or ESC to cancel entering the coating velocity.

8. Finally, press the MEAS key to return to the measurement screen and begin taking readings.

4. Press the OK key to delete All Files from memory, or the ESC key to abort.

5. Press the MEAS key to return to the measurement screen.

11.6 Editing a Grid (File)

Once a grid has been created and saved to memory, the user can edit the Comments or Increment Direction at a later time. The following procedures outline this process

2. Use the UP and DOWN arrow keys to scroll through the sub menu items until EDIT is highlighted.

3. Press the ENTER key to display the Edit List Box.

4. Use the UP and DOWN arrow keys to scroll through the Edit options until NOTE or INCR. DIR is highlighted.

NOTE: If editing the INCR. DIR, simply use the LEFT or RIGHT arrow keys to scroll NONE, NORTH, EAST, SOUTH, WEST for a Grid, or INC, DEC for a SeqLog. Proceed to step 10.

5. Press the ENTER key to activate the Alpha Edit box – Only used when editing the NOTE.

6. Use the UP, DOWN, LEFT, & RIGHT arrow keys to highlight the appropriate alpha characters.

7. Press the ENTER key to select a character and advance to the next eld of the Comments.

8. Use the CLR key to backspace if necessary.

9. Repeat steps 6 - 8 until the Comments are completed

10. Press the UP or DOWN arrow key to highlight SAVE CHANGES, and the OK key to activate the conrmation screen.

Deleting All Data

2. Use the UP and DOWN arrow keys to scroll through the sub menu items until DELETE ALL DATA is highlighted.

3. Press the ENTER key to activate the conrmation screen.

Known Coating Thickness

When the exact velocity of a coating is unknown, the user has the option of performing a one point calibration on a sample of the coating with a known thickness to determine the sound velocity. It would be very handy to carry a set of mechanical calipers to use in conjunction with the TI-CMXDLP for calibration in the eld:

1. Physically measure a location on a coating sample using a set of calipers or a digital micrometer.

IMPORTANT NOTE: In PECT (pulse-echo coating) mode, the coating sample must be coupled to metal in order to calibrate successfully. Simply place a drop of couplant on a piece of metal, lay the coating sample over the couplant on the metal and proceed to step 2.

2. Apply a drop of couplant on the transducer and place the transducer in steady contact with the coating (on metal) sample or actual test material. Be sure that the reading is stable and the repeatability indicator, in the top left corner of the display, is fully lit and stable. Press the MENU key once to activate the menu items tab. Press the MENU key multiple times to tab right and the ESC key multiple times to tab left until the CAL menu is highlighted and displaying the submenu items.

3. Use the UP and DOWN arrow keys to scroll through the sub menu items until COATING 1PT is highlighted.

4. Press the ENTER key to display the Digits Edit Box.

5. Press the UP and DOWN arrow keys to scroll the highlighted value.

6. Press the LEFT and RIGHT arrow keys to scroll the digit locations.

7. Repeat steps 5 & 6 until the known thickness value is correctly displayed.

8. Press the OK key to calculate the coating velocity and return to the menu screen, or ESC to cancel the one point calibration.

9. Finally, press the MEAS key to return to the measurement screen and begin taking readings.

NOTE: CHECK YOUR CALIBRATION! Place the transducer back on the calibration point. The coating thickness reading should now match the known coating thickness sample. If the thickness is not correct, repeat the steps above.

2.7 Measure

The TI-CMXDLP is now ready to measure. There are four different measurement view options, each with a specic purpose – Digits, RF, RECT, & B-Scan. The below outline how to toggle between the different view mode options:

Selecting the Measurement View Option

1. Press the MENU key once to activate the menu items tab. Press the MENU key multiple times to tab right and the ESC key multiple times to tab left until the DISP menu is highlighted and displaying the submenu items.

2. Use the UP and DOWN arrow keys to scroll through the sub menu items until VIEW is highlighted.

3. Use the LEFT and RIGHT arrow keys to scroll the view options.

4. Once the view is displayed, press the MEAS key to return to measurement mode.

DIGITS: Displays the digital thickness value using a large font size. This view is useful when the TI-CMXDLP is being used as a basic thickness gauge.

RF: Displays the actual waveform signal, much like an oscilloscope, from the reection of the opposite surface, pit, aw, crack or void. This view shows both the positive and negative peaks, and is often used to ne tune the scope settings, prior to inspection

RECT: Displays a half waveform signal, either positive or negative, from the reection of the opposite surface, pit, aw, crack or void. The user can select the polarity or “phase” displayed. This is typically determined by rst using RF view to select the most optimal polarity “phase”, to ne tune the scopes settings. The RECT view is commonly used as the primary “aw detection” view.

BSCAN: The Time Based B-Scan provides the user with a cross sectional view of the material being tested. This mode is useful when there is concern regarding the prole of the blind surface. This can also be a useful view when scanning for pits and aws.

Once the view has been selected according to the application requirements, the Delay and Range of the screen will potentially need to be adjusted, if the view has been set to RF or RECT. Alternatively, if BSCAN was selected, the B-Start and B-Depth settings will need to be adjusted. These settings serve the same purpose,with only differences in terminology. The Delay the same as B-Start, and the Range is the same as B-Depth. Therefore, these items will be grouped together for the duration of this manual, as follows: Delay (B-Start) and Range (B-Depth). Use the following steps to adjust these settings directly from the measurement screen as follows:

NOTE: The Delay (B-Start) and Range (B-Depth) are also used to adjust the parameters of Scan Bar.

1. Press the UP, DOWN, LEFT, and RIGHT arrow keys to scroll the target cell cursor to the desired storage location.

2. Press the ENTER key to save the current reading in the highlighted cell location. It’s as simple as that!

3. Press the MEAS key to hide the GRID/SEQ View Box, or ENTER to display it as necessary.

Note: Once the le is open, it will remain open until it’s closed or another le is opened by the user. If the gauge is powered off, the TI-CMXDLP will automatically open the le when powered on. Simply press the ENTER key to display the le from the measurement screen.

11.4 Viewing stored readings & A/B Scans

It is sometimes necessary to go back and view the stored readings and B-Scans using the TI-CMXDLP without a PC. The following procedures outline this process:

1. Press the MEAS key once to activate measure menu items. Press the MEAS key multiple times to move right and the ESC key multiple times to move left until the LOG cell is highlighted.

2. Press the ENTER key to display the Grid Log Box.

3. Press the UP, DOWN, LEFT, and RIGHT arrow keys to scroll the stored readings and corresponding display view. Notice as the cursor is moved to a different cell, the display will be updated with the display view saved with the reading. Readings stored in memory are indicated by displaying a MEM in the top left corner of the measurement screen.

In the upper left corner of each of the display photos above, is the repeatability indicator. The repeatability indicator is represented by six vertical bars and represents how repeatable the measurements are. In regular measurement mode,the TI-CMXDLP makes 8 measurements a second. In scan mode, the TI-CMXDLP makes 200 measurements a second. If the coating mode option is activated, the TI-CMXDLP makes 3 measurements a second in regular measurement mode and 65 measurements a second in scan mode. When the TI-CMXDLP is idle, only the left vertical bar will be displayed. However, when the TI-CMXDLP is making a measurement,four or ve of the bars should be displayed on the repeatability indicator. If fewer than four bars are showing, the TI-CMXDLP is having difculty achieving a stable measurement and the thickness value displayed is potentially unstable.

4. Press the OK key to select the coordinate or end ID and return to the Grid or Seq List Items screen, or ESC to cancel the selection and return to the Grid or Seq List Items menu.

NOTE: If there is not enough memory available to create the grid or sequential log, an error message box “NOT ENOUGH MEMORY“ will be displayed. Press the OK or ESC key to return to the Grid or Seq List Items menu. It may be necessary to free some memory in the TI-CMXDLP at this time. Refer to section 11.5 for more information on Deleting a File.

Selecting the Auto Increment Direction

The Auto Increment feature gives the user the ability to specify which direction to advance the cursor after storing a reading.

5. Use the UP and DOWN arrow keys to scroll through the new Grid or Seq List Items until INCR. DIR or DIRECTION is highlighted.

6. Use the LEFT & RIGHT arrow keys to toggle the Increment direction NONE, NORTH, EAST, SOUTH, or WEST for a grid, or INC, DEC for a sequential log.

7. When the correct Increment direction is displayed, continue on to the next section “Graphics”.

Saving Graphics

The TI-CMXDLP provides the user with the ability to save a snapshot of the display screen and all the current settings of the TI-CMXDLP with every reading, or just save the reading only. Saving the graphics might be advantageous to the user when the A/BScan views will be used to graphically save a picture of the scanned areas for reporting purposes. It might also come in handy when user requires backup of all the current TI-CMXDLP parameters for each reading. However, if neither of these requirements are necessary, this option should be disabled in order make more efcient use to the TI-CMXDLP storage capacity.

1. Use the UP and DOWN arrow keys to scroll through the new Grid or Seq List Items until SAVE GRAPHICS is highlighted.

2. Use the LEFT & RIGHT arrow keys to toggle the Increment direction to YES or NO.

3. Depending on which function is highlighted, use the LEFT, RIGHT, and Enter keys to scroll the options or activate the Digit Edit and List Box options.

3.2 Probe – Menu

ZERO PROBE: The TI-CMXDLP is zeroed in much the same way that a mechanical micrometer is zeroed. If the TI-CMXDLP is not zeroed correctly, all of the measurements made using the TI-CMXDLP may be in error by some xed value. The TI-CMXDLP is equipped with an optional automatic or manual zero feature. Refer to section 6.2, for an explanation of this important procedure.

ZERO COATING: In order to account for very slight electronic differences in transducers of the same type, frequency, and diameter, the TI-CMXDLP has been equipped with a “zero coating” feature. This enables the TI-CMXDLP to obtain very accurate readings on coatings, eliminating potential errors incurred from slight differences in the manufacturing processes. Refer to section 6.2.
