4. Install the transducer dummy block to verify the circumferential and axial
location. Center the indicator line on the block to line up with the scribed mark
(see Figure 1-17 below).

5. Loosen the transducer hold-down screw and tighten the J-hooks on the
clamping fixture. Be sure the bracket has not moved from its position.
1.4.5.3 Installing the
Second Bracket
with a Chain
Note: The following step requires the transducer spacing discussed on page 1-9.
1. Measure the spacing from the zero point (the point of circumferential origin).
Mark the spacing point with a crosshair on the opposite side of the pipe, 180°
from the zero point (as shown in Figure 1-18 below).

2. Carefully wrap the chain or strap around the pipe, taking care not to twist it.
3. Loosen the wing nuts up to the end of the J-hooks. Then hook the chain into the
tightest links and firmly hand tighten the wing nuts.
4. Line up the
other
edge of the CFG-PI holder bracket with the scribe line and
tighten the chain or strap, as shown in Figure 1-19 below.
