Refer to section 7.6. 11.1 Introduction to Grid and Sequential file formats The TI-CMXDLP is equipped with two data ile format options, GRID LOG and SEQ LOG. The GRID ile format is very similar to a spreadsheet format found in popular software programs like Excel. A GRID is simply a table of readings.
3.10 DATA – Menu 3. Use the LEFT and RIGHT arrow keys to scroll the Pulser Voltage options. NEW: Allows the user the ability to create a new alpha numeric grid, or sequential log ile with auto identiiers. It is equipped with custom parameters, rows, and columns depending on the user’s application reporting requirements. Refer to section 11.2. EDIT: Gives the user the ability to change parameters of grid or sequential ile previously saved.
3.12 XFER (Transfer) – Menu 10.12 Pulse Width The TI-CMXDLP has an adjustable pulse width option. Pulse width, refers to the duration of time the pulser is left on. This time results in increased energy sent into the test material. There are three width options (SPIKE, THIN, and WIDE). The SPIKE setting may be desirable for high resolution and general applications to decrease the overall noise. This can be considered the normal or standard setting.
3.17 Arrow Keys The Arrow Keys are used to navigate through the menus, increase/decrease values,and toggle speciic function keys. 3.18 ENTER key The ENTER key is used in the menu selection process to activate list and edit boxes, display and save measurements to grid or sequential iles locations. 3.19 MULTI MODE Key The MULTI MODE key opens a measurement mode screen, listing all the modes that are available to the transducer speciically selected, or auto detected.
Probe Zero Disk & Battery Cover 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 irm contact. Important: Be sure to follow the polarity labels located on the back label of the TI-CMXDLP.
4.0 PRINCIPALS OF ULTRASONIC MEASUREMENT 5. Once the desired law mode is displayed, press the MEAS key to return to measurement mode. 4.1 Time versus thickness relationship NOTE: All the features previously discussed in this manual can be used to adjust and ine tune the TI-CMXDLP while in Flaw Mode. Ultrasonic thickness measurements depend on measuring the length of time it takes for sound to travel through the material being tested.
4.5 Temperature Flaw Mode View Temperature has an effect on sound velocity. The higher the temperature, the slower sound travels in a material. High temperatures can also damage transducers and present a problem for various liquid couplants. Since the sound velocity varies with temperature it is important to calibrate at the same temperature as the material being measured. Refer to the diagram. The grey grid line, point (A), corresponds to 100% FSH(Full Screen Height).
V-Path Correction Dual element delay line transducers have two piezoelectric elements mounted at an angle on one end of the delay line. One element is used for transmitting sound, while the other element only receives sound. The two elements and their delay lines are packaged in a single housing but acoustically isolated from each other with a sound barrier. This allows the transducer the ability to achieve very high sensitivity for detecting small defects.
2. Use the UP and DOWN arrow keys to scroll through the sub menu items until VIEW is highlighted. 3. Press the ENTER key to display a list of the color scheme options. 4. Press the UP and DOWN arrow keys to scroll through the material list until the appropriate material is highlighted .5. Press the ENTER key, followed by pressing the OK key, to overwrite the current color scheme with the selected scheme. 6. Finally, press the MEAS key to return to the measurement screen and begin taking readings. 10.
5.0 SELECTING THE MEASUREMENT MODE 5.1 The setup library The TI-CMXDLP contains 64 user conigurable preset locations to store custom setups for easy recall. These setups can be optimized for the user’s speciic application needs and can also be stored on a PC and transferred bi-directionally using Electromatic’s PC interface software included with the instrument. The setups supplied with the instrument cover some of the more typical applications commonly used with this type of instrument.
measured without having to remove the coating prior to measuring. Users will often use pulse echo mode and echo-echo mode in conjunction when performing inspections on coated materials. Thru coating measurements require special high damped transducers. The most common transducers are the 3.5, 5, and 7.5 MHz hi-damped transducers. These transducers are suitable for use in both pulse-echo and echo-echo modes.
5.3 Factory Setup Chart Num Name 1 Enter Custom Name 3. Use the LEFT and RIGHT arrow keys to toggle the ALARM on/off/audible. Comment 1 Gn/AGC Velocity 4.

10.2 High Speed Scan 6.0 MAKING MEASUREMENTS The High Speed Scan feature of the CMXDL+ increases the overall repetition rate to a maximum of 140Hz with a high speed screen refresh rate of 25 times a second. This feature enables a user to make scanned passes over an arbitrary length of the test material, while still maintaining a reasonable representation of thickness over the scanned area or region.
Probe Automatically Recognized 1. Press the OK key once to use the identiied probe, or ESC to display a list of optional transducers. Note: if the TI-CMXDLP recognizes a speciic transducer, the user should always select OK to use the identiied 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, or the TI-CMXDLP has somehow identiied the probe in error.. 2.
6.2 Two Point Calibration NOTE: Use the minimum coating sample for the two point calibration. 1. Physically measure the thinner of the two samples of the coating, as close as possible to the minimum expected coating measurement range, using a set of calipers or a digital micrometer. VERY IMPORTANT: If coating measurements will be made with the coating applied to a metal surface, the calibration must be done in the same manner,with the samples coupled to a metal surface.
Performing a Manual Probe Zero (On Block) One Point Calibration 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. NOTE: Use the maximum coating sample for the one point calibration irst. 1. Press the OK or ESC keys to enter the main measurement screen and begin the manual zero process. 2.

range is .100” (2.54mm) to 1.0” (25.4mm), the user should calibrate on a known thickness sample close to 1.0” (25.4mm). 6. Repeat steps 4 & 5 until the velocity number is correctly displayed. NOTE: It’s always handy to carry a set of mechanical calipers to use in conjunction with the TI-CMXDLP for calibration in the ield. 7. Press the OK key to set the velocity and return to the menu screen, or ESC to cancel entering the velocity. One Point Calibration 8.
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. At some point there may become a requirement for improved accuracy over a smaller measurement range. In this case, a two point calibration would be most suited for the job.
Basic Material Type Measure Mode (Tabbed Menus) – (PECT & CT) If the material velocity is unknown, and a sample thickness cannot be taken from the material, the user may opt to choose a basic material type from a list with approximate velocity values according to various material types. It’s important to note that these velocities will not always be an exact representation of the material being tested. Use these values only if a close approximation is acceptable.
Probe Automatically Recognized (PECT only) 1. Press the OK key once to use the identiied probe, or ESC to display a list of optional transducers. NOTE: if the TI-CMXDLP recognizes a speciic transducer, the user should always select OK to use the identiied 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.
7.1 Display Views 9.0 PULSE-ECHO COATING & COATING TECHNIQUES DIGITS The Digits view is a basic digital thickness gauge look and feel. The larger digits make it much easier for the operator to monitor the thickness readings. The Scan Bar has also been added to the Digits view to provide the user with yet another visual tool for easily monitoring changes in thickness readings due to internal laws or defects. The following is a list of the viewable features on the display: 9.
The adjustment considerations in the example above will typically be used for all thrupaint applications respectively. In some applications the hold -off may be suficient,while a gain(AGC) or thresholds adjustment will solve the problem. A similarprocess of elimination should be considered for all thru paint applications. B-Scan. The B-Scan displays a time based cross section view of test material.
H. Coating Thickness Value – Displays the actual thickness of any coating adhered to a metallic material surface (PECT Mode), or a coating adhered to a non-metallic surface (CT Mode). I. J. Minimum Material Thickness – Part of the Alarm feature. Displays the minimum thickness value found during a scan. Maximum Material Thickness – Part of the Scan feature. Displays the maximum thickness value found during a scan. K. B-Scan Display – Cross section view of the material.
8.0 Thru Paint Measurement Technique 8.1 Introduction to Thru Paint Measurement The principle behind thru paint measurement is by measuring the time between twobackwall echoes returning from the test material. Since both of these backwall echoes travel the same path through the paint or coating, the thickness of the coating is subtracted out of the measurement so that only the actual material thickness can be measured.
7.2 7.3 Changing Display Options 6. Press the UP, DOWN, LEFT, and RIGHT arrow keys to scroll the highlighted value. The following procedure outlines how to select or toggle display options: 7. Repeat steps 3-6 until all the (?) values are correctly adjusted. 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.
located inside the dimensions of GATE1 (B). Therefore, the TI-CMXDLP cannot see (A)at all, with respect to the starting point of (B). Also notice, the position of the threshold level with respect to the baseline (D), which represents the sensitivity setting of the threshold. Extreme sensitivity is indicated by the bottom of the range(D) at the baseline, and less sensitivity indicated by the top of the range at (D).Therefore, the vertical height of GATE1 from the baseline, is the threshold level.
Adjusting the Range (B-Depth) Once again, just to reiterate, the Range (B-Depth) + Delay (B-Start) equals the right side of the screen. Therefore, the Range (B-Depth) is the overall area, from the delay, that will be viewable on the screen. The TI-CMXDLP digitizer will round up from the Range (B-Depth) that’s entered. Therefore, if the Range (B-Depth) is set at 1.0”, the digitizer will round this value up to the next adjustment available.
Activating the gates:· Adjusting the B-Scan Speed (color version only) Automatically: The gates are automatically activated, when a measurement mode is selected. Gate1 is active in all measurement modes. These modes have been internally setup at the factory. Therefore, if the user selects the Thru Coat (E-E) option, an internal setup will be loaded, and 2 gates will automatically be activated. This setup will work ine for the majority of all common applications.
The TI-CMXDLP has 110dB gain range, but has been limited to a 60dB gain range (-10 to 50 dB), for thickness gauge applications. The common starting point for standard thickness gauge applications is 46dB. This feature is used to increase/decrease the power or amplitude of the signal. When used in conjunction with the attenuator feature, it has a limited overall gain range of -30dB to 70dB. The gain can be adjusted to accommodate a variety of material types.
7.6 Understanding the features of the Gate IMPORTANT: It is recommended to spend some time in this section. The sections that follow are procedures for using the features associated with the Gates, in some way. There are 3 gates in the TI-CMXDLP, and as a result, operating and setting them up can become somewhat convoluted, to say the least. However, a thorough understanding of the functionality presented in this section, will reveal how easy they actually are to operate overall.
7.5 Threshold 5. Press the MEAS key to return to the measure screen and Hot Menu items. The Threshold is the level (sensitivity) of the signal amplitude required to trigger the thickness reading. This level can be used in conjunction with the gain. Example: suppose the user can visually see a potential law on the display, but the TI-CMXDLP is not detecting on the law because the Gain is too low, or the Threshold to high.
