Introduction The 2-Channel Model DF868 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 DF868’s advanced features.
Four submenus within the User Program provide access to the
various programmable features of the Model DF868. 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
DF868 be installed. The second channel connector may
simply be left vacant for future expansion.
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 DF868 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.
Figure 1-1: The Model DF868 Keypad
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.

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 (CH1/2 and GLOBL) and PIPE
submenus is necessary for operation of the Model DF868. 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, skip the corresponding sections of this chapter.
Except for the three submenus noted above, it is not necessary to
program the Model DF868 flowmeter in any particular order.
Therefore, the sections of this chapter need not be completed in
sequence. Proceed immediately to any section of interest.

OFF TRANS TRNFL
The Model DF868 flowmeter can take measurements in two ways:
? The Correlation Transit-Time? technique uses a pair of
transducers (either wetted or clamp-on) with each transducer
alternately sending and receiving coded ultrasonic signals through
the fluid. When the fluid is flowing, signal transit time in the
downstream direction is shorter than in the upstream direction; the
difference between these transit times is proportional to the flow
velocity. The DF868 measures this very small time difference and,
using various digital signal processing techniques combined with
programmed pipe parameters, determines the flow rate and
direction.
?
? The TransFlection technique uses two transducers. One
transducer shoots thousands of grouped ultrasonic pulses in very
rapid succession. The pulses bounce off “scatterers” in the liquid
(bubbles, solids, or liquid droplets) and are reflected back to the
other transducer. Each received pulse group receives a “snapshot”
of the flow. By comparing all snapshots and averaging out objects
that do not appear to move with the flow, the DF868 can determine
flow rate and direction.
Note: If the DF868 has not been ordered with TransFlection mode,
the TRNFL option does not appear.
Proceed directly to the next section to program the SYSTM submenu.

Use these two options to set the minimum and maximum time
interval between transmissions. Increasing the repetition period
reduces the amount of background noise in the signal at the expense
of reducing the maximum measurable flow rate. Since the DF868
adjusts repetition periods to optimize the flow measurement (taking
flow rate, transducer frequency, and signal characteristics into
consideration), you must enter a range, from 100 to 3200 μsecs. REP
PERIOD 1 specifies the shortest repetition period possible, with a
default of 200 μsec. REP PERIOD 2 specifies the longest repetition
period the DF868 can use, and defaults to a value of 800 μsec.
Note: Once the DF868 determines the appropriate repetition period
within the limits of REP PERIOD 1 and REP PERIOD 2, it
alternates between transmits at the determined repetition
period and a period that is 20% longer. For example, if the
DF868 selects a repetition period of 200 μsecs, it first
transmits a series of bursts at 200 μsecs, followed by a series
at 240 μsecs. The DF868 then compares the receive signals of
the first series of bursts to those of the second series. If the two
series of signals are too dissimilar, the DF868 displays an
incoherent signal error.

Note: To calculate the response time, divide the XMITS PER

apply only to the CH1/CH2 measurement mode and to the
SUM/DIF measurement modes, if either or both channels are
in error. Error handling in the AVE measurement mode is set
below.
The 2-path error handling option is intended for applications where
two sets of transducers are installed in the same location in the same
pipe to improve accuracy and the meter is operated in AVE mode.
With this function enabled, the Model DF868 performs error handling
only if both channels are in error. If this function is disabled, error
handling occurs when either channel goes into error.

MODBUS Register Map To request specific parameters from the DF868 via the MODBUS,
the control system must access the appropriate register number, as
shown in Table 1-33 on page 1-84. Only registers 1-84 are available
with the DF868 for MODBUS communications. Registers 508-512
are used by the DF868 to store the MODBUS parameters.
Note: If you request Ch2 or AVE data from a 1-Channel meter, the
values will all be zero.

The KV/SS Submenu The KV/SS submenu enables you to enter a table of values of the
kinematic viscosity (KV) based on signal strength (SS). You can then
use this table to calculate KV as shown in the KV/SS option (in the
ADVAN option of the SETUP submenu) discussed on page 1-47.
IMPORTANT: To use the option, you must enter the KV vs. SS pairs
in descending order of KV and ascending order of
SS. For example, if pair 1 is KV = 10 centistrokes
and SS = 62, then pair 2 must be KV ≤ 10
centistrokes and SS ≥ 62. The DF868 accepts 2 to 20
pairs.

Introduction This chapter explains how to display measurement data in various
formats. Each of the two display screen panes may be programmed
independently.
Note: The instructions in this chapter assume that the left display
pane is active. If the right display pane is active, simply
change all [F1]-[F4] designations to [F5]-[F8].
The following submenus are included in the Display Menu:
? BIG - displays a single measurement in large size text.
? DUAL - permits the simultaneous display of two measurements, in
the same screen pane, in standard size text.
? GRAPH - displays a graph of either velocity or volumetric flow
versus time.
? LOG - displays the data stored in a log file either graphically or
numerically.
? SIGNL - graphically displays any one of five transducer signals
versus time.
? BACKL - sets the time that the LCD display backlight remains on
before it is automatically turned off.
Proceed to the appropriate section to set up the Model DF868 display
screen(s), using one of the listed submenus. For convenience, a
complete flow diagram of the Display Menu is shown in Figure A-6
on page A-6 of Appendix A, Menu Maps.

Numeric Format The Model DF868 can log up to three parameters simultaneously.
Each set of data values is called a record, and up to 120 consecutive
records can be stored in a page. A log file can consist of up to 120
pages. The numeric log display, which shows one record at a time,
includes the following components:
? page number
? record number

Graphical Format (cont.) IMPORTANT: Only the first of the three logged parameters is
displayed in the Graphical Format of the LOG
submenu. Therefore, when creating a log file, be sure
to specify the parameter to be graphed at the 1st
Value Logged prompt. See Chapter 3, Logging Data,
for details on creating a log file.
In the typical graphical display shown, the first logged parameter
(VEL) is shown to the left of the y-axis and there is a message line
below the graph that initially indicates the starting date and time of
the current page. Notice that most of the locator bar has been replaced
by a status line in standard video that shows the value, units and time
of the record at the current cursor location. However, there is still an
inverse video pointer at the far right of this line to indicate that
additional option bar choices are available.
Note: The message line date includes only the day and the month
(not the year), and the times in the status line and the message
line include only the hours and minutes (not the seconds).
Because the times displayed in the LOG graph are in whole minutes
only, movement of the cursor may not result in a visible change in the
posted times. For example, if a TIME INCREMENT of 30 seconds has
been programmed, two presses of either cursor movement key will be
required to change the displayed time by one minute.

? Signal Selection: use the “1” and “2” keys to select a transducer
signal for display by scrolling through the list of available signals.
? Vertical Scaling: The “4” and “5” keys are used to scale the graph
vertically. Each press of the “4” key doubles the height of the
graph, while each press of the “5” key halves the height of the
graph. The three available scale factors are 1x, 2x and 4x.
? Horizontal Scaling: The “7” and “8” keys are used to scale the
graph horizontally. Each press of the “7” key doubles the T INC
value (2x horizontal compression), while each press of the “8” key
halves the T INC value (2x horizontal expansion). The four
available compression ratios are 1x, 2x, 4x and 8x.

Introduction This chapter explains how to use the Model DF868’s data logging
capability. The LOG menu, which is accessed by pressing the [LOG]
key on the keypad, is divided into four submenus:
? STD - used to log up to three of the available measurement data
parameters
? MEM - used to check the data logger memory to determine if the
specified log will exceed the available memory
? STOP - used to terminate current data logging activity
? ERROR - used to log any generated error messages.
Up to twenty standard or error log files may be created and stored in
battery-backed memory. Each log file contains up to three
measurement parameters, the log start time and date, the log end time
and date, the time interval between updates, and any error messages.
Error logs record data only when an error message is generated.
The Model DF868 allocates up to 120 pages of memory, each of
which can contain up to 120 records, for data logging. Each page is
assigned a header, to distinguish one page from another. The header
contains the log title, start date and time, end date and time, and the
time increment. Each record contains the date and time of the
measurement and the values for the three logged parameters.
Note: Each log file uses at least one page of memory, and the same
page can not be shared by two different logs.
Since a fixed amount of memory is allocated for data logging, the
number of active logs, the log time increments, and the length of the
log runs will all affect how much memory is available for additional
logging. For example, a log that updates every 5 seconds will use
more memory than a log that updates every 6 minutes, assuming that
they both run for the same length of time.
After a log file has been created, it may be displayed, printed, cleared
or uploaded to a personal computer. Refer to the appropriate chapters
of this manual for specific instructions.
Refer to Figure A-8 on page A-8 in Appendix A, Menu Maps, and
proceed to the appropriate section for the desired LOG submenu.
Each submenu may be followed in the sequence shown or the [↑] and
[↓] keys may be used to scroll through the prompts.

The time increment is the frequency at which the Model DF868 takes
and records data measurements. If any reading takes longer than the
programmed time increment, the log is filled in with the next
consecutive reading. For example, assume that a velocity value of 3
ft/sec is recorded at 12:00:00 in a log with a time increment of five
seconds. If the next reading is 8 ft/sec and it takes the meter 12
seconds to read this value, then both of the missed readings (12:00:05
and 12:00:10) will be filled in with the 8 ft/sec value.

pages expected to be used by all currently programmed logs is given.
If the number of pending pages exceeds the number of free pages,
additional memory may be made available by clearing some old logs
(see Chapter 5, Clearing Data, page 5-4).
Logging Data 3-11
April 2003
The MEM Submenu If it is undesirable to delete old logs to free up additional memory, the
number of pages pending may be reduced by altering the parameters
(cont.)
of one or more of the currently active logs. For example, either
increasing the time increment or decreasing the total logging time
will reduce the memory requirements for a log file. Use the following
equations to calculate the number of pages used by a log:
length of log
number of records = ------------------------------------ (3-1)
time increment
number of records
number of pages = -------------------------------------------- (3-2)
120
Consider a log that is set to run for 24 hours with a time increment of
3 minutes. From Equation 3-1 above, the number of records = (24 x
60)/3 = 480 records. Then, from Equation 3-2 above, the number of
pages = 480/120 = 4 pages. Thus, at least four pages of memory must
be available for this log to run to completion. Notice that either
increasing the time increment to 6 minutes or decreasing the length of
the log to 12 hours would reduce the memory requirement to only 2
pages.

Introduction The Model DF868 flowmeter has the capability to print any of the
data stored in its memory via the built-in RS232 communications
port. In order to use the function, the RS232 port must be connected
to a printer with a serial port input. (A printer with a parallel port
input may be used with a third-party serial-to-parallel adapter.)
Note: See Chapter 1, Installation, of the User’s Guide for
instructions on wiring the RS232 port. For additional
information, refer to Chapter 6, Serial Communications, and
to the brochure EIA-RS Serial Communications (916-054).
After connecting the Model DF868 to a printer, the Print Menu is
used to print live or logged data in either numeric or graphical format.
In addition, any site files stored in memory may be printed. The Print
Menu is divided into the following submenus:
? PRNTR - use to specify the printer currently connected
? DATA - use to print live data in numeric or graphical format
? LOG - use to print a log file in numeric or graphical format
? PROG - use to print a site file
? STOP - use to terminate any active print jobs
For purposes of this discussion it is assumed that the left pane of the
data display screen is active. If the right pane of the data display
screen is active, all of the instructions remain the same, except that
any references to the [F1]-[F4] keys should be replaced by the [F5]-
[F8] keys.
Refer to the flow diagram in Figure A-7 on page A-7 of Appendix A,
Menu Maps, and proceed to the desired section for detailed
instructions. Any submenu may be followed in the sequence shown or
the [↑] and [↓] keys may be used to scroll through the prompts.
Note: If a printer has not yet been set up, the instructions in The
PRNTR Submenu section must be completed before
proceeding to any of the other submenus.

Introduction The Model DF868 flowmeter is equipped with a standard RS232
serial interface. By using this interface, any log files stored in the
DF868’s memory may be easily uploaded to a personal computer. In
order to accomplish this, the following steps must be completed:
Note: See EIA-RS Serial Communications (916-054) for a more
detailed discussion.
? Connect the DF868 to the personal computer
? Check the DF868 baud rate setting
? Set up the personal computer’s terminal software
? Transfer the log files to the personal computer.
This section also contains instructions for setting up an RS485 serial
interface.
Wiring the RS232 The first step is to connect the built-in RS232 port in the DF868 to
one of the serial ports (COM1 or COM2) on the personal computer.
Interface
Table 6-1 below lists the standard cables available from GE
Panametrics for this purpose.
Table 6-1: GE Panametrics Serial Cables
Part Number PC Connector DF868 Connector
704-659 DB25 Male Flying Leads (5)
704-660 DB9 Male Flying Leads (5)
704-661 DB25 Female Flying Leads (5)
704-662 DB9 Female Flying Leads (5)
Each of the cables listed in Table 6-1 above is available in several
standard lengths. However, a user-supplied cable may be used, if
preferred. In either case, wire the DF868 end of the serial cable in
accordance with the pin designations listed in Table 1, page 12 of the
brochure EIA-RS Serial Communications (916-054).
Note: For serial communications between a single DF868 and a
single personal computer, no connections are required to pins
4 and 5 of the DF868’s serial connector. However, these pins
should be jumpered together to ensure proper operation.

EIA-RS Serial Communications (916-054).
Note: For computers operating under other operating systems,
contact GE Panametrics for assistance or consult the
operating system manual supplied with the computer.
6-2 Serial CommunicationsApril 2003
The Optional RS485 Although the standard RS232 serial interface included with the
Model DF868 is adequate for most applications, GE Panametrics
Serial Interface
offers an optional RS485 serial interface upgrade for special
situations. The Model DF868 is easily modified to provide RS485
communications, and this section describes the wiring and use of the
special RS232 to RS485 converter.
Note: For compliance with the European Union’s Low Voltage
Directive (73/23/EEC), this unit requires an external power
disconnect device such as a switch or circuit breaker. The
disconnect device must be marked as such, clearly visible,
directly accessible, and located within 1.8 m (6 ft) of the
electronics console.
Interface Converter A special bracket containing the serial interface converter and a three-
terminal barrier strip is mounted inside the Model DF868, just below
Mounting
the RS232 terminal block (see Figure 6-1 below). The standard
RS232 terminal block is wired to the input of the serial interface
converter, and the RS-485 output of the serial interface converter is
wired to the barrier strip.

Point-To-Point Wiring Standard factory wiring of the RS485 serial interface is configured
for point-to-point wiring. That is, a single Model DF868 may be
wired directly to a single personal computer. To connect the RS485
serial interface, refer to Figure 6-1 on page 6-4 and complete the
following steps:
Note: For compliance with the European Union’s Low Voltage
Directive (73/23/EEC), a transparent plastic shroud protects
the electrical connections. The shroud must remain in place,
except while wiring the unit. Reinstall the shroud after the
wiring has been completed.
1. Disconnect the main power to the electronics console and open the
cover.
!WARNING!
Dangerous voltages exist within the electronics
console. Do not perform any wiring operations until
the main power to the unit has been disconnected.
2. For units so equipped, remove the clear plastic shroud that covers
the electrical connectors.
3. Using a twisted-wire pair, connect the XMT+ terminal of the
barrier strip to the T+/R+ terminal of the PC’s RS485 adapter and
connect the XMT– terminal of the barrier strip to the T-/R-
terminal of the PC’s RS485 adapter (see the documentation
provided with the RS485 adapter for details).
Note: The XMT+ terminal on the barrier strip is the screw opposite
the red wire connection and the XMT– terminal on the barrier
strip is the screw opposite the green wire connection.
4. Reinstall the clear plastic shroud (for units so equipped), close the
cover to the electronics console and reconnect the main power.
The RS485 serial interface is now ready for point-to-point operation.
IMPORTANT: The installed version of the Model DF868 software
must be Version F2Z or higher to support RS485
operation. If necessary, contact the factory for
information about a software upgrade.
6-4 Serial CommunicationsApril 2003
Multi-Point Wiring The standard point-to-point wiring configuration for the serial
interface converter may be modified to permit the use of a multi-point
wiring arrangement. In a multi-point RS485 system, one flowmeter
(the master) is connected to the personal computer, while a number of
additional flowmeters (the slaves) are chained together and connected
to the master flowmeter. In order to implement such a system, the DIP
switch settings inside each serial interface converter must be changed.
IMPORTANT: The serial interface converter in the last slave unit in
the chain should not be reconfigured.
Reconfiguring a Serial To reconfigure a serial interface converter for multi-point wiring,
complete the following steps:
Interface Converter
1. Disconnect the main power to the electronics console and open the
cover.
!WARNING!
Dangerous voltages exist within the electronics
console. Do not perform any wiring operations until
the main power to the unit has been disconnected.
2. For units so equipped, remove the clear plastic shroud that covers
the electrical connectors.
3. Remove the serial interface converter mounting bracket by
removing the standoff located just below the RS232 terminal
block and the grounding screw just to its left (see Figure 6-2 on
page 6-6).
4. Loosen the two screws that fasten the DB9 connector to the
mounting bracket, and remove the serial interface converter from
the bracket.
5. Use a small screwdriver to pry open the plastic case of the serial
interface converter, as shown in Figure 6-2 on page 6-6.
The serial interface converter contains a main printed circuit board
and a daughter printed circuit board. The daughter board has a small
terminal block attached to it and the main board has a DIP switch
(SW1) mounted near the center of the board.
6. Locate the switch assembly on the main board, and move the
switch in position 1 from ON to OFF. The standard ON state for
this switch is for point-to-point operation, while the OFF state is
needed for multi-point operation. See Table 6-2 on page 6-6 for
the proper settings of all four switches on the switch assembly.

7. Reassemble the serial interface converter and secure it to the
mounting bracket with the two mounting screws.
8. Reinstall the mounting bracket into the electronics enclosure and
secure it with the standoff and the grounding screw.
Wiring the System After the serial interface converters have been configured for multi-
point operation, the system can be wired.
1. Using twisted-wire pairs, connect the XMT+ terminals of all the
flowmeters together and connect the XMT– terminals of all the
flowmeters together.
IMPORTANT: Make sure that the flowmeter with the non-modified
converter is wired as the last unit in the chain.
2. Using a twisted-wire pair, connect the XMT+ terminal of the
barrier strip to the T+/R+ terminal of the PC’s RS485 adapter and
connect the XMT– terminal of the barrier strip to the T-/R-
terminal of the PC’s RS485 adapter (see the documentation
provided with the RS485 adapter for details).
6-6 Serial CommunicationsApril 2003
Wiring the System Note: The XMT+ terminal on the barrier strip is the screw opposite
the red wire connection and the XMT– terminal on the barrier
(cont.)
strip is the screw opposite the green wire connection.
3. Reinstall the clear plastic shroud (for units so equipped), close the
cover to the electronics console and reconnect the main power.
The RS485 serial interface is now ready for multi-point operation.
IMPORTANT: The installed version of the Model DF868 software
must be Version F2Z or higher to support RS485
operation. If necessary, contact the factory for
information about a software upgrade.
