The User Program 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.
Programming of the ACTIV, SYSTM 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, those sections of this chapter may be skipped.
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.
Note: To enter calibration data, please refer to Chapter 1,
Calibration, of the Service Manual.

Activating a Channel The ACTIV submenu permits selection of the desired measurement
method. While following the programming instructions, refer to
Figure A-1 and Figure A-2 in 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 Transit-Time mode, or [F2] to
activate the channel in TransFlection mode.
Note: The current status of the meter is displayed in the bottom line
of the prompt area.
The Model DF868 flowmeter can take measurements in two different
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 a customer has not ordered the DF868 with TransFlection
mode, the TRNFL option does not appear.
Procedure Options To leave the User Program and return to measurement mode, press
[EXIT] on the keypad. If changes have been made in any of the
submenus, the program will ask if you wish to save the changes. Press
[F1] to return to measurement mode without saving the file or press
[F2] to enter the SAVE submenu.
Note: See the SAVE submenu section on page 1-52 of this chapter for
more information on this function.
