DigitalFlow™ Multipurpose Ultrasonic Liquid Flowmeter Startup Guide (1- and 2-Channel) 17
Chapter 2. Initial Setup
Chapter 2. Initial Setup
2.1 Introduction
This chapter provides instructions for entering the minimum amount of programming data required to place the Model
DF868 flowmeter into operation. Before the Model DF868 can begin taking measurements and displaying valid data,
the system and pipe parameters must be entered. In addition, if you plan to use both channels of a 2-channel meter, each
channel must be activated prior to use. Additional programming options provide access to the more advanced features
of the Model DF868, but this information is not required to begin taking measurements.
Note: See the Programming Manual for information on those User Program options not covered in this chapter.
2.2 Navigating Through the User Program
In order to begin using the Model DF868, the following submenus within the User Program will be accessed:
• ACTIV - enables selection of the desired measurement method (for a 2-Channel meter, it is also used to activate a
channel)
• SYSTM - prompts the user to enter the required system data
• PIPE - prompts the user to enter the required pipe parameters
As a guide in following the programming instructions in this chapter, the relevant portions of the Model DF868 menu
map have been reproduced in Figure 11 on page 31 and Figure 12 on page 32.
Note: There are minor differences at the start of the
ACTIV and SYSTM submenus for the 1-Channel and 2-Channel
models, but the PIPE submenus are identical.
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]. Be sure to record all programming data in Appendix B,
Data Records.
Use the keypad, as described in the Programming Manual, 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.
