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.

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.
