Introduction The Model AT868 flow transmitter has a user program that provides
access to the various programmable features of the unit. To program
the AT868 you can use the internal keypad or Panaview™, a PC-
based, non-resident software program that communicates with the
AT868 through its serial port.
Note: If you are using Panaview™, the AT868 is configured with the
Meter Address as 1 and the baud rate as 9600.
This section describes step-by-step programming instructions using
the internal keypad. For more information on programming using
PanaView™, refer to Appendix F, PanaView™PanaView™.
Refer to the appropriate section for a discussion of the following
PROG features:
• CHx-ACTIV - activate one or both channels/paths.
Note: The AT868 uses two channels or paths to make more accurate
flow measurement by averaging, substracting or adding the
channels/paths together.
• CHx-SYSTM - select volumetric, totalizer and mass flow units and
other parameters.
• CHx-PIPE - enter the pipe geometry and other parameters.
• CHx-I/O - set up the analog and totalizer/frequency outputs.
• CHx-SETUP - set the signal limits, response times and activating
mass flow.
• GLOBL-SYSTM - select system units (English and metrics).
• GLOBL-I/O - set up error handling, outputs and display.
• GLOBL-COMM - set the serial port parameters.
Note: The “x” in CHx represents the channel/path number. If you are
using a single channel meter, only Channel 1 will appear.
To get the AT868 up and running as quickly as possible, you must (as
a minimum) activate the channel/path(s) and enter channel/path data,
global system data, and pipe parameters. At the end of each section
are directions that will help you in programming required (quick
startup) and optional data.
Also, as a programming aid, a complete set of menu maps for
PROG
are included in Appendix A, Menu Maps. The specific figure
numbers will be referenced throughout this chapter.
Note: In this manual, only the programming of Channel 1 will be
described. To program Channel 2 of a 2-channel/path meter,
simply repeat the same procedures presented for Channel 1.
