Transducer Placement
To place the transducer, tighten the positioning clamp jaws onto the transducer handle;
See Figure 3 for Positioning Clamp details. Loosen the two positioning clamp knuckles
and insert the transducer head into the degassed water at an angle to minimize disruption
of the degassed water. Verify that the transducer surface is uniformly wetted (no
bubbles). If it is not, gently wipe the surface clean using your finger. Position the
transducer head so it is directly facing the center of the conical target and
submerged 1/8”
to 1/4” in the degassed water. Tighten the two positioning clamp knuckles to hold the
transducer in place; See Figure 4 for placement details. Small measurement variations
will occur due to placement of the transducer. Try various positions above the target to
achieve the best results.
