Introduction This chapter provides instructions for entering the programming data
required to place the CTF878 flowmeter into operation. Before the
CTF878 can begin taking measurements and displaying valid data,
the current system and pipe parameters must be entered. Additional
programming options provide access to the more advanced features of
the CTF878, but this information is not required to begin taking
measurements.
Powering UP Immediately upon power up the CTF878 emits a short beep and
displays a “PCI Loader” message. It then validates the instrument
programming, and displays the GE Sensing logo and the software
version. If the meter fails any of these tests, contact the factory.
After the meter conducts all the self checks, the screen then appears
similar to the one shown in Figure 1-1 below.

Using the Screen The essential features for operating the CTF878 are the screen and
keypad. Although these features are common, the CTF878 design
offers particular features to simplify and speed operation. The new
menu system is very user-friendly; program information is now
located on tabbed forms instead of on a long, linear menu.
The primary function of the screen is to display information in order
for you to take measurements accurately and easily. The CTF878
screen consists of those parts shown in Figure 1-2 below.
Figure 1-2: CTF878 Screen in Operate Mode
The top line of the screen is the status bar, which normally displays
the time and date. However, when you press [MENU] (the menu key),
the menu bar replaces the status line.
The middle of the screen is the work area, which displays the
measured parameters, numeric measurements, and both bar and line
graphs. When you enter a selection on the menu bar, this area displays
menu prompts. A line at the bottom of the area also displays error
code messages, which are described in more detail in the Service
Manual.

Using the Screen (cont.) The system tray displays icons that indicate meter operations not
otherwise shown. Table 1-1 below lists the icons and their meanings.
The bottom of the screen displays the three function key options: F1,
F2 and F3. These keys have different functions, depending on the task
being performed. The initial, factory setup, configuration for these
keys is as follows:
•F1 = Transducer
•F2 = Diagnostics
•F3 = Save Now

programming instructions, see the Program Menu Map, Figure 1-34
on page 1-37.
Figure 1-4: Program Menu
To scroll to a particular option, press the [T]or [S] arrow keys until
you reach the option. Then press [ENTER] to open the option window.
When entering parameters in an option, press:
•The [T] key to step through the available parameters
•The [S] key to scroll back to a previously entered parameter
•The [F2] key (Cancel) or the [ESC] key to exit an option at any time
and return to Operate Mode without changing the parameters.
Note: The Transducer, Pipe, Fluid and Path parameters are
categorized under the same Transducer/Pipe menu, as shown
in Figure 1-5 below. You can be more time-efficient by
programming the parameters in all four entries under
Transducer/Pipe before exiting the menu.

Parameters (cont.)
Upon your selection, a warning screen appears similar to Figure 1-7
below. In three out of four warnings, the Receiver Board option
number appears as part of the text.
IMPORTANT: If SPECIAL is selected as the transducer type, a
number does not appear, however, the warning still
states that the transducer selection must match the
Receiver Board.
Figure 1-7: Transducer Selection Warning Screen
The Receiver Board option number corresponds to the frequency
range selected with the original order (see Table 1-3 below).
4. Compare the Receiver Board option number listed on the
WARNING screen with the one assigned to your CTF878.
Note: The Receiver Board option number is the last digit of the
CTF878’s model number. That model number can be found on
the label attached to the inside of the front cover. In
Figure 1-8 below the Receiver Board option number is 3.

Parameters (cont.)
The program now varies, depending on whether you have selected
typical or special transducers.
•If you have selected a typical transducer, the CTF878 comes
programmed with the needed parameters. Proceed to
Parameters for Typical Transducers below.
•However, if your application requires entering a special
transducer / receiver option, go to the next section, Parameters
for Special Transducers on page 1-9.
Parameters for Typical
Transducers If a typical transducer has been selected, the user must:
1. Enter the transducer wedge temperature (Wedge Temp) text box
and press [ENTER].
2. Type in the value (provided by the factory) and press [ENTER].
3. Proceed to Entry Confirmation on page 1-10.
Parameters for Special
Transducers
Note: The factory will supply the information required below with a
special transducer / receiver option.
The user must enter the appropriate transducer / receiver operating
frequency range.
IMPORTANT: The CTF878 flowmeter and the transducers have the
same fixed frequency band of operation defined by
the customer's application. The frequency printed on
the transducers represents a frequency band of
operation and does not always match the up or down
frequencies.
1. From the Transducer prompt, press the [T] key to reach the
Frequency Up (Frq Up) prompt, and press [ENTER].
2. A drop-down list of thirty-six frequencies opens, ranging from
0.222 to 8.00 MHz. Scroll to the correct frequency, and press
[ENTER].
3. Repeat the same selection process for the Frequency Down
(Frq Dn) prompt.
Next, you must enter the transducer wedge angle (Wedge Ang) and
wedge soundspeed (Wedge SS).
4. Scroll to the appropriate text box and press [ENTER].
5. Type in the value (provided by the factory).
Note: If you enter an incorrect numeric value, press the [W] key to
erase the last digit entered.
6. Once the value has been entered, press [ENTER] and proceed to
Entry Confirmation below.

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.
