2.2 Making Measurements
Step 1: Apply couplant to the test block or material at the spot to be
measured. In general, the smoother the material surface, the
thinner the couplant may be. Rough surfaces require more
viscous couplant such as gel or grease. Special couplants are
required for high temperature applications.
Step 2: Press the tip of the transducer to the surface of the material
to be measured. Use moderate to firm pressure and keep the
transducer as flat as possible on the material surface.
Step 3: Read the material thickness on the gage display.
Note: For highest accuracy both a velocity and zero
calibration must be done.
2.3 Low Battery
The gage will operate for at least 150 hours on one set of batteries
under normal conditions (not in FAST mode and with backlight off).
The battery symbol in the bottom right corner of the display indicates
remaining battery life.
