NOTES
1.0 INTRODUCTION
The Electromatic TI-CMXDL is an ultrasonic thickness gauge that measures with extreme versatility. It has the ability to simultaneously measure coatings and material thicknesses while maintaining the ability to locate pits, flaws and defects in the material. Based on the same operating principles as SONAR, the TI-CMXDL 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.
NOTE: Inherent in ultrasonic thickness measurement is the possibility that the instrument will
use the second rather than the first 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 insufficiently 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.

2.0 QUICK-STAR T GUIDE
Turn the TI-CMXDL on and off using the switch located on the bottom right corner of the key pad. When TI-CMXDL is initially turned on, a flash logo and blinking lights are displayed. Th the gauge attempts to identify the currently attached transducer (probe). The TI-CMXDL has a “Auto Probe Recognition” feature that attempts to identify special transducers with feature bui in . If the TI-CMXDL doesn’t find a transducer so equipped, the user must select a transducer from the Probe Type list. The following sections outline each scenario.
NOTE: This section is primarily written as a basic startup guide only.
2.1 TI-CMXDL Overview
In order to understand how to operate the TI-CMXDL, it’s best to start off with an understanding of what it is we’re looking at exactly.

2.2 Auto Probe Recognition
When the TI-CMXDL 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-CMXDL recognized the probe type:
1. Press the OK key once to use the identified probe, or ESC to display a list of optional transducers.
NOTE: If the TI-CMXDL recognizes a specific
transducer, the user should always select OK to use the identified 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-CMXDL recognized the probe and the OK key was pressed, the TI-CMXDL will advance to a Zero Probe menu. If the transducer was identified as a special transducer capable of measuring coating thickness, a menu will be displayed allowing 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, 6.0.

14.0 LOW BAT TE RY INDICATOR & CHANGING THE BATTERIES
The TI-CMXDL has a Battery Strength Indicator (illustrated here) that provides the user with information about the remaining strength of the batteries. There are 11 steps from 100% (full) to 0% (empty). As the battery voltage drops, the number of pixels that are dark will be reduced. When the battery outline is nearly empty, we suggest changing the bateries. Any type of AA size battery can be used including alkaline (1 time use) or rechargeable.
There is no re-charging function provided with this gauge, so rechargeable batteries will have to be recharged externally. Please note that alkaline batteries will provide a longer run time then most rechargeable types.
14.1 Battery Replacement
The battery cover is the large round disk shown in the photo. This disk is also the Proble Zero Plate. To remove it and expose the batteries, unscrew the disk by carefully turning it counterclockwise.
Remove the old batteries and insert three fresh AA batteries with the polarity as indicated here (also shown on the label on the back side of the gauge). Replace the battery cover being careful not to over tighten.
Battery Cover & Probe Zero Plate
2.3 Selecting the Transducer Type
If the TI-CMXDL does not identify a specific transducer type on initial power up, the user will be required to select a type from a predefined list of types by diameter and frequency. By selecting a transducer type from a predefined list, the TI-CMXDL can recall specific properties about the transducer.
NOTE: Once the transducer has been selected, the TI-CMXDL will store and recall this transducer type every time the TI-CMXDL 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-CMXDL 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:
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 over write 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 & One Point Calibration
The next steps are to perform a probe zero and calibrate the TI-CMXDL to the material and transducer being used. If the sound velocity is unknown, the TI-CMXDL can be calibrated to a known thickness sample. This demo will briefly explain both of these techniques.
The TI-CMXDL is equipped with two zero options:
Off Block Zero (Automatic Probe Zero) – When this feature is enabled the
TI-CMXDL will do an electronic zero automatically, eliminating the need for a zero
disk or block.
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.
Both zero procedures are outlined as follows:
Off Block Zero (Automatic Probe Zero)
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 at the right will be briefly displayed followed by the main measurement screen. The TI-CMXDL is ready to be calibrated.

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.
12.5 Using the Default Setup
The default setup feature was added to the CMX to use, as a last resort, if there are no setups stored in the gauge –factory or otherwise. The only time this might possibly occu if the setup file in the CMX was somehow corrupted, and the user does not have access computer to re-load the factory setups back into the CMX. This gives the user the ability load and modify a basic setup 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 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 CMX is equipped with a language option. Currently, the only languages supported a English, Spanish, and German. The steps to select one of these languages are outlined a 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 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 LANGUAGE is highlighted.

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 confirmation screen.
6. If a coating transducer was identified 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-CMXDL. 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 on 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-CMXD for calibration in the field:
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.

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 thickness reading should now match the known thickness. If the thickness is not correct, repeat the steps above.
2.5 Coating Calibration
The TI-CMXDL has been preset to a default coating velocity of 0.0850 in/µsec (2159 m/sec). This will be very close to the most common coating material velocities used in the field. 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-CMXDL. However, if the velocity is unknown, the TI-CMXDL can also be calibrated to a specific 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-CMXDL, rather than have the TI-CMXDL 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

12.3 Saving a Setup
Once the TI-CMXDL parameters and features have be adjusted for an application, the u may elect to save these setting to a specific setup location for future use. This can poten tially save time and reduce error between users.
It is sometimes necessary to rename a previously saved setup, or add additional commen 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 co ments about the project may also be required for additional documentation purposes. Th following procedures outline the necessary steps for saving and editing a setup:
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 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
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 fields have been edited.
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.
-61-
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-CMXDL for calibra­tion in the field:
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.

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 th TI-CMXDL, the number of potential applications also increases based on ability alone. This is primarily in reference to the addition of those very difficult 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. Becau of the additional time involved, the TI-CMXDL has been equipped with the ability to sa these setups to memory and be recalled at any time. The TI-CMXDL can store up to 64 custom setups. These setups can be bi-directionally 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 the same job or project. This feature also eliminates error between two or more users du ing the setup and calibration process.
12.2 Opening a Setup
Once user setups are saved (refer to Section 11.3, p. 47), they are opened (recalled for u using the following procedure. Please make sure that the correct probe is connected and matches the probe selection stored in this setup.
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 OPEN is highlighted.
3. Press the ENTER key to display the Setup List Box.
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 confirmation screen.
6. Press the OK key to load the setup from memory.
7. Press the MEAS key to return to the measure 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-CMDL for calibration in the field:
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.

2.6 Zero Coating
To account for very slight electronic differences in transducers of the same type, frequen and diameter, the CMX has been equipped with a “zero coating” feature. This enables t CMX to obtain very accurate readings on coatings, eliminating potential errors incurred from slight differences in the manufacturing processes. The procedure is outlined below
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 zero.
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 confirmation 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.
11.7 Changing the active File - Open
The user may have transferred grid/seq templates from a PC to the TI-CMXDL, or setup grids/seq using the TI-CMXDL at an earlier time. The name of the cur­rently active file 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 file is currently active, but also be able to change the active file 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 confirmation screen.
6. Press the OK key to load the file from memory.
7. Press the MEAS key to return to the measure screen.
