10. Mark along the new fold (Figure 4-12).

11. Draw a horizontal line along the pipe from the center line of the 3 o'clock transducer
position (Figure 4-13). Use a level to ensure that the line is level with the top of the
pipe. This line should be at least 3 inches (76 millimeters) longer than the transducer
spacing calculated in Menu 25. For example, if the spacing is calculated to be 14 inches
(356 millimeters), draw a 17 inch (432 millimeter) line.

12. Measure the spacing (obtained from Menu 25) from the inside edge of the 3 o'clock
transducer, and mark this on the pipe (Figure 4-14).
