3. Measuring Thickness 3.1 Instrument Calibration Before using PM-5 series, set the sound velocity of the material to be measured, without calibrating the instrument and probe, the thickness of the work-piece can be measured directly.When the sound velocity of the material to be measured is unknown, calibration can be selected to find out the sound velocity of the material to be measured, which is very important.The calibration function is divided into two types:... - Page 6 FILE NUMBER – Select the current file. Total 400 files and each file 3.2 PRESET OTHER SPECIFICATIONS could save 252 thickness values or wave-forms. PROBE SETUP: D15X (means single crystal delay probe) Press MODE to enter the specification configuration interface, which MEASURING MODE: including many specification adjusting options like FILE NUMBER, The Thickness Gauge has 4 measurement modes:...

In the A-scan interface, press the bottom right button NEXT highlight the value to be adjusted.
- Page 10 3.5 Real Class Analysis of A-SCAN 1. When measuring the thickness, it’s possible that that over small gains prevent the precise results. As showed in the following figure, the thickness of the testing object is about 5mm, but as for the over small gain, the measuring result is 10.77mm as the first echo has not broken the gate and the gate locates the second echo automatically.
