Summary of Contents for Check-line TI-CMX
- Page 1 Additional Features TI-CMX ........
- Page 2 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. The principle advantage of ultrasonic measure- ment over traditional methods is that ultrasonic measurements can be performed with access to only one side of the material being measured.
- Page 3 In order to understand how to operate the TI-CMX, it’s best to start off with an understa ing of what it is we’re looking at exactly. The TI-CMX has a lot of great features and to that will prove to be a huge benefit for the variety of applications you’re constantly facin on a continual basis.

- Page 6 SING THE TILITY OFTWARE 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 12.1 Computer System Requirements known thickness sample.

- Page 8 Coating Calibration the Setup. The TI-CMX 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. 14. Finally, press the MEAS key to return to the measurement If the velocity of the coating is known, and different than the above default setting, the user screen.
- Page 9 11.3 Saving a Setup Known Coating Thickness Once the TI-CMX parameters and features have be adjusted for an application, the user When the exact velocity of a coating is unknown, the user has may elect to save these setting to a specific setup location for future use. This can poten- the option of performing a one point calibration on a sample of tially save time and reduce error between users.

If example, some cast materials are very granular and porous and as a result have inconsistent the transducer was identified as a special transducer capable of sound velocities.

The TI-CMX will also see to it that this occurs by view of the material. The B-Scan view draws simply forcing the gauge into this mode when zero.
