Introduction The Model GF868 flowmeter cannot provide accurate flow rate
measurements until the instrument has been properly installed and the
basic system and pipe parameters have been programmed into the
meter. See the Startup Guide for detailed instructions on performing
these tasks. After completing the installation and initial setup, use this
chapter to program the Model GF868’s advanced features.
Ten submenus within the User Program provide access to the various
programmable features of the Model GF868. Step-by-step
programming instructions are presented in this chapter. Refer to the
appropriate section for a discussion of the following User Program
submenus:
•ACTIV - select the desired measurement method
•SYSTM - enter the system data
•PIPE - enter the pipe parameters
•I/O - set up the inputs and outputs
•SETUP - set the signal limits and response times
•CLOCK - set the time and date
•COMM - set the serial port parameters
•SAVE - save site files
•RECLL - recall stored site files
•SECUR - enter a passcode
As an aid in following the programming instructions, a complete
menu map of the User Program is included in Appendix A, Menu
Maps.
Note: In the menu map drawings, plain text represents prompt area
messages and boxed text represents option bar choices. Fx
represents a function key to select an option bar choice.

Using the Keypad The Model GF868 keypad contains 39 keys, which are labeled with
their primary (unshifted) functions. In addition, pressing the red
[SHIFT] key will access the secondary functions assigned to most of
the keys.
The complete keypad is illustrated in Figure 1-1 below and a detailed
description of both the unshifted and shifted functions for each of the
39 keys is listed in Table 1-1 on page 1-3.
Note: Only the [SHIFT] key and the eight [Fx] keys have no shifted

Obtaining On-line Help A context-sensitive, on-line help system is programmed into every
Model GF868 flowmeter. On-line help, which displays additional
information related to the current task, may be accessed at any time
by pressing the [HELP] key on the keypad. The help information will
be shown on the currently selected pane of the display screen, as
shown in Figure 1-2 below.
Figure 1-2: Typical On-Line Help Screen
After entering the on-line help system, the following functions are
available on the option bar of the selected display pane:
•MORE: Press [F1] (or [F5]) to access this function, and the next
screen of text is displayed in the prompt area.
•EXIT: Press [F2] (or [F6]) to access this function, and the Model
GF868 returns to measurement mode.
•ERROR: Press [F3] (or [F7]) to access this function, and the
various Model GF868 error codes are displayed. Use the [F1]-[F4]
(or [F5]-[F8]) function keys, in conjunction with the [←] and [→]
keys, to obtain additional information on the desired error code or
to exit the help system.
Note: See the Service Manual for a complete listing of all error
codes and messages
•FLOW: Press [F4] (or [F8]) to access this function, and the various
flow measurement parameters are displayed. Use the [F1]-[F4] (or

Using the Console
Control Keys The Model GF868 has four console control keys, which are located
on the left side of the keypad. Use these keys, which are described
and pictured in Table 1-1 on page 1-3, in accordance with the
following instructions:
1. Use the top console control key to adjust the audio alarm volume.
Discrete presses will incrementally increase the volume of the
audio alarm. Hold the key down for continuous increase. Use the
key in shifted mode to decrease the volume of the audio alarm.
2. Use the second console control key for the stopwatch totalizer.
Press the key once to start the stopwatch totalizer. Press the key
once, in shifted mode, to stop the stopwatch totalizer.
Note: Instructions on properly setting up the stopwatch totalizer are
given later in this chapter. Also, the Service Manual provides
information on the error response of the stopwatch totalizer.
3. Use the third console control key to adjust the display backlight.
Discrete presses of this key will increase the backlight brightness
through settings of Off, Mid and Full. Discrete presses of this key
in shifted mode, will decrease the backlight brightness through
settings of Full, Mid and Off.
Note: The display backlight has an automatic time-off feature. See
the Programming Manual for setup instructions.
4. Use the bottom console key to adjust the display contrast.
Discrete presses will incrementally increase the display contrast.
Hold the key down for continuous increase. Use the same key, in
shifted mode, to decrease display contrast.

Entering Programming
Mode Use the keypad, as described in the previous section, to navigate
through the User Program. The menu map may be followed in
sequence, or the [↑] and [↓] keys may be used to scroll through the
prompt screens. The [←] key may be used to delete the last
alphanumeric character that was entered from the keypad.
The following discussion assumes that the left screen pane is active.
If the right screen pane is active, only the function key designations
change. That is, replace [F1]-[F4] with [F5]-[F8].
Note: Be sure to record all the programming data entered in this
chapter in Appendix B, Data Records.
To access the User Program, press the [PROG] key on the keypad.
The standard measurement mode screen is replaced by the following
initial programming mode screen:
Note: If the security feature is active, enter the password and press
the [ENT] key to enter the User Program. See the SECUR
submenu section of this chapter for more information on the
security feature.
Programming of the ACTIV, SYSTM and PIPE submenus is necessary
for operation of the Model GF868. Failure to accurately enter all of
the required information will result in unreliable flow rate data.
Therefore, be sure to complete at least the sections of this chapter
pertaining to those three submenus.
Note: Because it is so essential, instructions for programming the
ACTIV, SYSTM and PIPE submenus are also included in the
Startup Guide. If that programming has already been
completed, those sections of this chapter may be skipped.
Except for the three submenus noted above, it is not necessary to
program the Model GF868 flowmeter in any particular order.
Therefore, the sections of this chapter need not be completed in
sequence. Proceed immediately to any section of interest.
PROGRAM Start Press the [←] and [→] keys and
one of the function keys [F1]-[F4]
to select the desired submenu.
From this screen, press [EXIT] to
return to measurement mode.

Activating the Channel The ACTIV submenu permits selection of the desired measurement
method. While following the programming instructions, refer to
Figure A-1 on page A-1 of Appendix A, Menu Maps.
1. Enter the ACTIV submenu by pressing [F1] at the User PROGRAM
prompt.
2. Press [F1] to activate the channel in BURST mode.
Note: The current status of the meter is displayed in the bottom line
of the prompt area.
3. Press [F1] to select Skan mode or [F2] to select Skan/Measure
mode. The meter will exit the ACTIV submenu and return to the
channel menu screen.
The Model GF868 flowmeter can take measurements in two different
ways:
•Skan is a low resolution technique for locating the acoustic signal
and for high velocity measurements. It is more robust in a noisy
environment than the Measure technique.
•Measure is a more precise technique best used for low velocity
measurements.
If Skan is selected at the next prompt, the instrument uses this
technique exclusively. However, if S/M is selected, the meter uses
Skan to find the acoustic signal and then tries to use the Measure
technique for a more precise measurement.
Note: To change the Skan and Measure parameters, see the SIGNL
submenu section of this chapter.
What’s Next? After completing the above steps, the meter returns to the User
PROGRAM prompt. Continue as follows:
•To continue programming the meter, refer to the menu maps in
Appendix A and navigate to the desired menu. Then, proceed to
the appropriate section of the manual for instructions.
•To leave the User Program and retain the previous settings,
press [EXIT] and then press [F1] = NO at the SAVE prompt. Any
programming changes will be discarded and you will be
returned to the data display.
•To leave the User Program and return to measurement mode,
press [EXIT] and then press [F2] = YES at the SAVE prompt.
Your programming changes will be entered into the meter’s
memory, and you will be returned to the data display.
