2. The next prompt asks if you wish to measure the pipe wall with the
internal thickness gauge. If you press
[ENTER], the program moves to
the T-Gauge Display option (as covered on page 159). When you have
completed setting up and using the thickness gauge (as discussed in
Chapter 8), press
[F2] or [F3] to return to the Pipe tab.
3. For pipe diameter, two alternatives are available. At the Diameter
prompt, the meter asks for the pipe outside diameter and thickness. But
if you have selected certain pipe materials (carbon or stainless steel,
cast iron, PVC and CPVC), you have the option of entering the pipe
dimensions by a standardized schedule. Once you enter the nominal
pipe size and identification, the PT878 determines the OD and wall
thickness from an internal table.
