How to Measure How to Measure
1. Apply couplant to the surface of your part.
2. After power-up, place the probe FLAT on the surface and press down.
3. Lift the probe when you hear a double BEEP or see the green indicator light
blink. Measurement result is displayed on the LCD.
A second reading may be taken at the same spot by
simply holding the probe down on the surface.
4. When completely finished, wipe the probe clean
of couplant then return both Gage and probe to the
protective case. There is no need to disconnect the
probe from the Gage during storage.
Couplant Couplant
Couplant is required to propagate ultrasound into the coating. Water is a good cou-
plant for smooth coatings. Use the supplied glycol gel for rougher coatings. While it
is unlikely that the couplant will damage the finish or leave a stain on the surface,
we suggest testing the surface by using the couplant on a sample. If testing indi-
cates that staining has occurred, a small amount of water can be used instead of
couplant. Consult the Material Safety Data Sheet available on our website and your
coating supplier if you suspect the couplant may damage the coating. Other liquids
such as liquid soap may also be used.
