A. Prepare the tested workpiece, refer to "6.1 Surface
Treatment of Measured Workpiece".
B. Insert the probe into the instrument and turn it on.
C. Instrument calibration. Refer to "7.5 Instrument Calibration".
D. Inversely measure the speed of sound. The sound speed of
the workpiece is uncertain, and the sound speed must be
measured back to obtain the correct sound speed of the
workpiece. Refer to "7.6 Reverse Measurement of Sound
Velocity".
E. Measure the thickness. Use the inversely measured sound
velocity value to measure the thickness of the workpiece of
the same material.
Note: When not in use for a long time, fully charge the product
first, and recharge it every six months to avoid battery damage.
