Setup For Measuring Thickness Of Materials Other Than Steel

The TI-45N 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 disc, the gauge should display the “Equivalent Value” listed in
the Table in section 6.4, instead of 0.197" or

5.0 mm

for steel.

To determine the proper acoustic velocity for measurement of the non-steel
material, refer to the Acoustic Velocity Selection Table in section 6.4. After
determining the proper acoustic velocity, the gauge must be changed to this new
value as described in section 6.6

Changing The Acoustic Velocity Settings

If you do not know the type of material to be measured or the material type is not
listed in the Acoustic Velocity Selection Table, refer to section 6.5, S

etup Of

Gauge When Acoustic Velocity is Unknown.
