2.5.5 Installing the Transducers
To install the transducers into the mounting bracket, complete the following steps:
1. If necessary, loosen the thumb screw on the movable transducer clamp to
permit axial positioning.
2. Note that the fixed transducer clamp is set at the zero mark on the scale.
Position the movable transducer clamp so that it aligns with the mark on
the bracket’s graduated scale that matches the calculated transducer
spacing. Measurement markings should be read on the side of the
transducer clamp indicated by the arrows. Typically, set the holder on the
left to the zero position and the other holder to the desired spacing.

Note: The required spacing between the transducers varies based on many
factors. The tablet APP automatically calculates your transducer spacing.
(see
“Viewing the Transducer Spacing” on page 73 ).
3. Tighten the thumb screw to lock the movable transducer clamp into place,
being cautious not to disturb the established axial positioning.
