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.
If you select a material that has the Schedule option, and you wish
to use that alternative:
a.
The prompt asks if you wish to apply ANSI (the ANSI schedule). Press
[ENTER]
to select (or deselect) the ANSI box.
Note:
Selecting the ANSI box enables you to use the Schedule alternative
b.
Press the [
] key twice to move the prompt to the Nominal pipe size drop-down menu. Press
[ENTER]
to
open the menu. Scroll to the desired pipe size, and press
[ENTER]
to confirm your choice.
c.
Press the [
] key to move the prompt to the Schedule drop-down menu. Press
[ENTER]
to open the menu.
Scroll to the desired schedule, and press
[ENTER]
to confirm the choice.
•
To confirm the entries and return to Operate Mode, press
[F3]
(OK).
•
To leave the window without confirming the entries, press
[F2]
(Cancel) or the
[ESC]
