location and press
[
S
]
and
[
T
]
to increase or decrease the

Obtain the required information by measuring either the pipe
outside diameter
(OD)
or circumference at the transducer
installation site. The data may also be obtained from standard pipe
size tables found in
Sound Speeds and Pipe Size Data manual
(914-004).
3.
Enter the know thickness of the pipe wall by using the arrow keys.
