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.
