Taking Thickness Measurements

Taking ultrasonic thickness measurements is a straight forward
process that involves first making sure the surface is clean and
prepared, applying an ultrasonic couplant gel then placing the
probe on the surface and observing the display for the
measurement.

Zeroing the Probe (twin element probes)

When a twin element probe is connected to the gauge (and the
gauge is set to the correct probe) you must first perform a Probe
Zero before you can begin taking measurements. For instructions
see Probe Zero Function on page 35.
It is recommended to frequently perform a Probe Zero if
conditions such as temperature are changing.

Taking the Thickness Measurement

1.
Remove all scale, rust, dirt or loose
coatings and brush the test area clean.
2.
Apply ultrasonic couplant to the test
surface.
3. Place the probe-face on the clean,
lubricated test surface and make firm
contact applying gentle pressure.
4. The gauge will display a thickness
measurement.
(Or an indication of Echo Strength if no
valid measurement has been found in
Multiple Echo mode).
