3) Automatic non-linear compensation: within the full range, computer software is used to
correct the non-linear errors of the probe for the purpose of improving the accuracy
4) The upward and downward adjustment keys enable prompt selection of sound velocity,
thickness, and check the thickness memory units
5) Prompt for coupling state: provide coupling indication and the observation of the stability
of the indication can tell if the coupling is normal
6) Ten thickness values can be stored without loss after turn-off, which is very convenient for
measuring in field and high platform
7) Measuring sound velocity: according to the test block’s thickness, sound velocity can be
measured directly needless to search in the conversion table
8) Sound velocity of five different materials can be stored
9) Low voltage indication
10) Automatic turn-off
11) All keys enclosed----oil proof for longer service life
4. Switch between metric and imperial
This instrument can display in two units, metric or imperial. When the instrument is off, push
key, and then push ON key to turn on the instrument, so to achieve the function of
Imperial-metric
conversion
Metric display:
m/s is metric unit of sound velocity; mm is metric unit of thickness
Imperial display:
inch/
μ
s is imperial unit of sound velocity; Inch is imperial unit of thickness

5.1 Preparations for measurement
Put the probe into the probe socket of the unit, push ON-key to turn on the unit. As it is shown in
the figure below:
Full display screen
Sound velocity of last turn-off will be shown after the full screen displays for a few seconds. The
measurement can start now.
