As a result, the gauge should be ready to measure once the transducer has been connected. The TI-UMX2 can use two different styles of transducers; dual element and single element membrane. As a result, the gauge will be configured according to the transducer style purchased, as follows: 2.1 factory setup Parameters (single element Menu structure) 2.

8. Reboot your computer. 9. Power on the TI-UMX2 that should already be connected to your PC. 10. Press and hold the single TI-UMX2 button, located on the top end cap, until the top level menu options begin scrolling on the alpha display. Once this occurs, the button can now be released. The menu options will scroll one to the next in a time delayed sequence, and will display all the menu options in a continuous loop.
Press & Long Hold: Primary function – manually turn off the TI-UMX2. 3. Plug either the RS232 into a serial port, or USB connector into a USB port on the PC. The TI-UMX2 will automatically shut off after 5 minutes if it hasn’t detected a measurement.However,tobesuretheunitisshutoffafteruse,whenthebuttonis pressed and held down for approximately 10 seconds, “POWER” “OFF” will be displayed, and the unit will manually turn off.

The diagram below illustrates the entire menu structure of the TI-UMX2: 13.1 Introduction to firmware Firmware is the actual software, in the TI-UMX2 itself, that controls the functionality of the gauge. A benefit of the TI-UMX2, is the ability to upgrade the firmware from your desktop.
4.0 Menu & ConneCTor referenCe 6. Power on the TI-UMX2, and give it a minute to fully boot up. 4.1 7. Click the UP ARROW icon to initiate the file transfer. A dialog box will appear, displaying the examples folder created by DataComm on your desktop. Alternatively, the upload can be initiated from the menus by clicking the FILE menu option, followed by clicking the UPLOAD TO GAUGE option. Menu options sTore: This menu displays the current storage location of the TI-UMX2.
Uploading the Setup File 1. Remove the bottom end cap of the TI-UMX2, in order to access the LEMO data jack. Remove the rubber plug from the data jack. 2. Plug the LEMO connector into the data jack. Note: align the red pin on the connector with the data jack. 3. Plug either the RS232 into a serial port, or USB connector into a USB port on the PC. 4. Start the DataComm utility software. Zero: The TI-UMX2 can use two different types of transducers, a dual or single element.
MaTerIal: The TI-UMX2 includes a list of common material types with standard set velocities. It’s important to note that the velocities associated with these materials are general velocity values only. Materials of the same type, can have varying grades and consistencies. As a result, the material velocity will also have slight variations. A custom velocity has been implemented for this reason, and can be programmed via DataComm PC software. Refer to section 7.3 for further info. 3.

Refer to section 8.0 for further information on upgrading the TI-UMX2: 12.1 Introduction to setups LT ON – Enables all the LED’s and display back lights. The TI-UMX2 has been programmed with 8 of the most common material types used intheield.
Transducer Connectors The transducer connectors and single control button are located on the top end cap of the TI-UMX2. The transducer connectors are a special underwater Lemo “00”. noTe: There is no polarity associated with connecting a dual element transducer.

2. When CLEAR is displayed, immediately press and release the button to enter the sub menu options. CLEAR followed by the current storage location will alternate (CLEAR…A1…CLEAR…A1). 3. When CLEAR or LOCATION(A1) are being displayed, immediately press and release the button to clear the current location in the TI-UMX2. For this example, A1 has been selected as the storage location. 4. Press and hold the button to escape out of the sub menu options at any time.
5.0 PrInCIPles of ulTrasonIC MeasureMenT 5.1 Time versus thickness relationship Ultrasonic thickness measurements depend on measuring the length of time it takes for sound to travel through the material being tested. The ratio of the thickness versus the time is known as the sound velocity. In order to make accurate measurements, a sound velocity must be determined and entered into the instrument. The accuracy of a thickness measurement therefore depends on having a consistent sound velocity.
2. When TI-UMX2 is displayed, immediately press and release the button to enter the sub menu options. Again, the options will begin scrolling in a continuous loop (LT ON, LT OFF,LAUTO,MEMON/OFF,UPGRAD). The sound frequencies used in ultrasonic thickness measurement do not travel through air efficiently. By using a liquid couplant between the transducer and test piece the amount of ultrasound entering the test piece is much greater. 5.5 3.
Since pulse-echo only requires one reflection, it is the most sensitive mode for measuring weak reflections (flaws) typically found when measuring heavily corroded metals. V-Path Correction Dual element delay line transducers have two piezoelectricelementsmountedatanangleon one end of the delay line. One element is used for transmitting sound, while the other element only receives sound.
11.4 Connecting to a PC Pulse Echo Coating Mode – Coating On (PECT) Now that the log file has been created and saved on the PC, the next step is connecting to a PC to transfer the template file into the TI-UMX2. There are 2 cables included with the TI-UMX2 kit; LEMO to 9 pin serial and 9 PIN serial to USB. Serial: The LEMO to 9 pin RS232 cable can be connect directly to any serial port. However,theserialportnumbermustbeknown.

10.0 Pulse-eCHo CoaTInG & CoaTInG TeCHnIQues 10.1 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.
3. When the material type is displayed, immediately press and release the button to configure the TI-UMX2 to the selected material type. For this example, IRON has been selected. 4. Press and hold the button to escape out of the menu options at any time. 5. The TI-UMX2 is now calibrated and ready to begin taking readings.
9.0 THru-PaInT MeasureMenT TeCHnIQue 8.0 addITIonal feaTures & oPTIons 9.1 8.1 Introduction to Thru Paint Measurement (dual element Probes) The principle behind thru paint measurement is by measuring the time between two back wall echoes returning from the test material. Since both of these back wall 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.
The procedures to adjust the Gain are outlined below: 1. Press and hold the single TI-UMX2 button, located on the top end cap, until the top level menu options begin scrolling on the alpha display. Once this occurs, the button can now be released. The menu options will scroll one to the next in a time delayed sequence, and will display all the menu options in a continuous loop. 3. When the desired light option is displayed, immediately press and release the button to set the option in the TI-UMX2.
