Introduction The 2-Channel Model GS868 flowmeter cannot provide accurate
flow rate measurements for either channel until the instrument has
been properly installed, the channel has been activated, 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, proceed with this chapter to
program the Model GS868’s advanced features.
Four submenus within the User Program provide access to the
various programmable features of the Model GS868. Step-by-step
programming instructions for each submenu are presented in this
chapter. Refer to the appropriate section for a discussion of the
following User Program submenus:
•CH1/CH2 - use this submenu to activate a channel and to enter the
basic setup parameters for that channel.
•GLOBL - use this submenu to enter global meter parameters (i.e.,
clock, system, input/output, communications and security), which
apply to both channels.
•SAVE - use this submenu to store both channel and global data in
the meter’s memory, as a site file.
•RECLL - use this submenu to recall and activate a stored site file.
Note: It is not required that both channels of a 2-Channel Model
GS868 be installed. The second channel connector may simply
be left vacant for future expansion.
As an aid in following the programming instructions, a complete set
of menu maps for the User Program is included in Appendix A,
Menu Maps. The specific figure numbers will be referenced
throughout this chapter, as required.
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 GS868 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
function.

Note: Although the keypad is essentially the same, the front panel
layout of meters supplied in one of the optional enclosures is
different. See Appendix C, Optional Enclosures, of the Startup
Guide for a picture of the applicable front panel.

Using the Console
Control Keys The Model GS868 has four console control keys located on the left
side of the keypad. Use these keys, which are described and pictured
in Table 1-1 on page 1-3, as follows:
Audio Alarm Volume 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.
Stopwatch Totalizer 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.
Display Brightness 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
page 2-15 for setup instructions.
Display Contrast Use the bottom console key to adjust the display contrast.
Discrete presses will incrementally increase the display contrast.

The User Program Use the keypad, as described in Chapter 3, Operation, of the Startup
Guide 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]. Also, Channel 1 is used
in all examples, but the instructions apply equally to Channel 2.
Note: Be sure to record all the programming data entered in this
chapter in Appendix B, Data Records.
Programming of the ACTIV, SYSTM (CH1 and GLOBL) and PIPE
submenus is necessary for operation of the Model GS868. 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 (CH1 and GLOBL) and PIPE submenus are also
included in the Startup Guide. If that programming has
already been completed, skip the corresponding sections of
this chapter.
Except for the three submenus noted above, it is not necessary to
program the Model GS868 flowmeter in any particular order.
Therefore, the sections of this chapter need not be completed in
sequence. Proceed immediately to any section of interest.

prompt shown on page 1-8, the following screen appears:
Based on the selection made above, proceed to the appropriate section
of this chapter for instructions.
Activating a Channel The ACTIV submenu activates a channel and selects the desired
measurement method. While following the programming instructions,
refer to the menu map in Figure A-1 on page A-1.
1. Enter the ACTIV submenu by pressing [F1] at the Channel PROGRAM
prompt.
2. Press [F1] (OFF) to deactivate the channel and return to the
Channel PROGRAM prompt, or press [F2] to activate the channel in
BURST mode.
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.
:As indicated in the above prompt, the Model GS868 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 on page 1-20.
Procedure Options After completing the above steps, the meter returns to the Channel
PROGRAM prompt. Continue as follows:
