3.3 Probe

The probe transmits and receives the ultrasonic sound waves which the
TI-25M uses to calculate the thickness of the material being measured. The
probe must be used correctly in order for the TI-25M to produce accurate
and reliable results.
A small amount of "coupling" fluid, commonly called "couplant" is used to
insure that there are no air gaps between the probe and the material surface.
Grasp the probe by the molded rubber grip and place it on top of the mater-
ial surface. Apply moderate pressure to the top surface of the probe with
your index finger (A) or thumb (B) to stabilize the probe and to keep the
wearface seated flat against the measurement surface.
