2. For pipe diameter, two alternatives are available. The meter asks for the pipe outside diameter (
OD
) and wall
thickness (
Wall
). 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 (
Nominal
) and identification (
Schedule
), the CTF878 determines the OD and wall thickness from
an internal table.
If you want to use the diameter alternative (available for all materials):
a.
You must select from two choices, outside diameter or circumference.
• The prompt moves to the outside diameter (
OD )
text box. Type the OD (in mm or in., whichever is displayed)
into the box, and press
[ENTER]
to confirm your choice,
or
•
Move the prompt to the circumference (
ODxPI
) text box. Type the circumference (in mm or in., whichever is
displayed) into the text box, and press [ENTER] to confirm the choice.
b. In either case, the next prompt asks for the wall thickness. Type the value (in mm or in., whichever is
displayed) into the box, and press [ENTER] to confirm your choice.
Note: The measurement units shown depend on the choices made in the English/Metric window or the Meter
Settings menu. You can, however, change the measurement units in any text box by moving to that box and
pressing the F1 key.
