1.0 NOTES INTRODUCTION The Electromatic TI-CMX 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-CMX is capable of measuring the thickness of various materials with accuracy as high as ± 0.001 inches, or ± 0.01 millimeters.
NOTES 2.0 QUICK-START GUIDE Turn the TI-CMX on and off using the switch located on the bottom right corner of the keypad. When TI-CMX is initially turned on, a flash logo and blinking lights are displayed. Then the gauge attempts to identify the currently attached transducer (probe). The TI-CMX has an “Auto Probe Recognition” feature that attempts to identify special transducers with feature built in .

2.4 APPENDIX A: VELOCITY TABLE Probe Zero & One Point Calibration The next steps are to perform a probe zero and calibrate the TI-CMX to the material and transducer being used. If the sound velocity is unknown, the TI-CMX can be calibrated to a known thickness sample. This demo will briefly explain both of these techniques.
12.0 USING THE UTILITY SOFTWARE 12.1 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, Windows 2000 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.
7. Repeat steps 5 & 6 until the known thickness value is correctly displayed. 8. Press the OK key to calculate the 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 thickness reading should now match the known thickness. If the thickness is not correct, repeat the steps above. 2.
10. Press the ENTER key to activate the Setup List Box. Known Coating Thickness 11. Use the UP and DOWN arrow keys to scroll through the setups until the target location to save the Setup is highlighted. 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.
Selecting the Measurement View Option 11.3 Saving a Setup 1. Press the MEU 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 sub menu items. Once the TI-CMX parameters and features have be adjusted for an application, the user may elect to save these setting to a specific setup location for future use. This can potentially save time and reduce error between users.
.0 SETUPS, CREATE, STORE, EDIT & RECALL 11.1 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-CMX, the number of potential applications also increases based on ability alone.
3.0 KEYBOARD, MENU & CONNECTOR REFERENCE 3. Press the LEFT and RIGHT arrow keys to scroll the digit locations. 4. Repeat steps 2 & 3 until the DIFFERENTIAL value is correctly displayed. 3.1 Menu Key (Operation & Sub Menus ) The Menu key activates the primary menu structure containing 8 menu tab groups. These tab groups then contain sub menu items, or functions. The sub menu items have been organized in tab groups according to how closely they are related to the individual tab group names.
Setting the Alarm Low Limit MATL 2PT: Performs a two-point calibration. This option allows the user to automatically calculate the velocity by entering a second known sample thickness. Refer to section 6.3 for further info. 1. Assuming the ALARM is ON, use the UP and DOWN arrow keys to scroll through the sub menu items until ALARM LOW is highlighted. VELOCITY: Function is to calibrate the TI-CMX by setting the velocity to a known material velocity. Refer to section 6.3 for further info. 2.
DEFAULT SETUP: Loads a basic default setup. Use only as a last resort when the setups in the TI-CMX have been corrupted and a computer is not accessible. Refer to section 11.4 for further info. LANGUAGE: Provides the user the ability to select different languages for the TI-CMX. Refer to section 11.4 for further info. 3.
2. Apply a drop of couplant on the transducer and place the transducer in steady contact with the thinner of the two coating and samples. 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.
Probe Zero Disk & Battery Cover One Point Calibration Refer to Diagram: The Battery cover is the large round disk shown in the diagram. Note: This same disk is also used as a probe zero disk. Simply remove the cover when replacing the batteries (3 AA cells). When performing a manual probe zero function, simply place the transducer on disk making firm contact. NOTE: Use the maximum coating sample for the one point calibration first.
2. Apply a drop of couplant on a piece of metal and place the coating sample on the metal over the couplant. Apply a drop of couplant on the transducer and place the transducer in steady contact with the coating and 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.
Normal temperature range 9.3 Most standard transducers will operate from 0∞F to 180∞F. Known Velocity High temperature measurements Special transducers and couplants are available for temperatures above 180∞F up to 650∞F with intermittent contact. It is necessary to cool the transducer, by submerging the transducer in water between readings, when measuring high temperatures.
Probe Automatically Recognized (PECT only) Searching for small defects 1. Press the OK key once to use the identified probe, or ESC to display a list of optional transducers. Dual element delay line transducers are especially useful in searching for small defects. In the pulse-echo mode with high amplifier gain, very small defects can be measured. This is very useful during corrosion inspections overall.
5.0 SELECTING THE MEASUREMENT MODE 9.0 PULSE-ECHO COATING & COATING TECHNIQUES 9.1 5.1 The setup library 5.2 Introduction to Pulse-Echo Coating Measurement (PECT) In the previous sections we’ve discussed the need for detecting pits and flaws (pulseecho) in materials, along with the requirement to measure through and eliminate errors caused by coated materials (echo-echo). Until now, both modes were needed in order accomplish both tasks.
8.0 THRU-PAINT MEASUREMENT TECHNIQUE 8.1 Coating Only The coating only mode should be used when the application calls for coating measurements only and the user is not interested in the thickness of the material the coating has been applied to. This mode can also be used as a stand alone coating thickness gauge, where the coating has not been applied to another material surface. An auto identified coating probe must be attached to the TI-CMX in order to enable this mode.

4. Alternatively, press the ENTER key to display the Digits Edit Box. 5. Press the UP and DOWN arrow keys to scroll the highlighted value. 6.0 TAKING MEASUREMENTS The steps involved in making measurements are detailed in this section. The following sections outline how to setup and prepare your TI-CMX for field use. Overall range (B-DEPTH) An automatic or manual zero must always be performed. The auto zero is an off block electronic zero that does not require a zero reference block.
2. Assuming the TI-CMX recognized the probe and the OK key was pressed, the TI-CMX 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 proceed to the Probe Zero section that follows.
The following is a list of the viewable features on the display: Performing an Auto Probe Zero (Off Block) A. Repeatability/Stability Indicator – This indicator should be commonly 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-CMX is reliably measuring the same value 3 to 200 times per second, depending on which measurement mode and features are enabled. 1.
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-CMX. 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. 6.
7.0 USING THE DIGITS AND B-SCAN DISPLAYS A key feature of the TI-CMX is the ability to toggle between two different display options, Digits and B-Scan. The Digits view provides the user with a large digital readout of the thickness. Both views also include a scan bar features that uses a bar graph to indicate thickness.
Two Point Calibration 3. Press the ENTER key to display the list of material types. 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.
