This analyzer has two modes of operation:
1. Process. Instrument displays process measurement.
2. Menu. Instrument displays prompts that allow
change to operating parameters such as alarms,
output range, calibration, etc. While in this mode,
the Process measurement and communications
with other instruments are disabled. A timeout
feature automatically retur ns the analyzer to
the Process mode 5 minutes after the last key
is pressed.
The Model 2700 analyzer has eight keypads on the front
of the unit. See

dedicated to specific functions.
The functions of the other four keypads are defined in
software. Abbreviated messages appear above each
keypad which identify their current use. Descriptions of
these abbreviated messages are given in
Section 2.4 .
The displays and prompts used to set up the analyzer
operating variables, configuration (start-up), and cali-
bration are addressed in separate sections.

identified as MENU (F1) on the Process display is used
to change the mode of operation from the Process dis-
