TI-44N Operating Instruction Guide 1.0 WARRANTY INTRODUCTION The CHECK•LINE® TI-44N Thickness Gauge measures the wall thickness of metals, glass, ceramics and many rigid plastics. This gauge uses the “pulse-echo“ principle of ultrasonic testing where a short ultrasonic signal is transmitted from the probe. The signal travels through the measurement sample until it is reflected back towards the probe from the back side of the material.

TI-44N Operating Instruction Guide TI-44N Operating Instruction Guide 3.0 APPENDIX The TI-44N Thickness Gauge is supplied from the factory set for an acoustic velocity of 5930 m/sec for the measurement of steel. To measure the thickness of any other material, the acoustic velocity must be changed. When checking the built-in calibration sample, the gauge will display the “Equivalent Value” listed in the Table in section 6.1, instead of 0.197" (or 5.0 mm) 3.

The current acoustic velocity setting will be momentarily displayed prior to entering the Measurement Mode (Mode H). The display should then read 0.000 inch (or 0.00 mm). If the Good Coupling Indicator is flashing on and off, the red transmit connector of the probe is not connected properly. 4.

To measure the thickness of any other material, the acoustic velocity must be changed. When checking the built-in calibration disc, the gauge should display the “Equivalent Value” listed in the Table in section 6.1, instead of 0.197" or 5.0 mm for steel.
