4.1 Introduction
Once the analyzer has been installed, it can be configured for your
application. To do this you will:
• Establish and start an automatic calibration cycle, if desired.
(Electrically operated valves required.)

autoranging or select a fixed range of analysis, as required.
• Calibrate the instrument.
• Set alarm setpoints, and modes of alarm operation (latching,
failsafe, etc).
• Establish a security password, if desired, requiring Operator to
log in.
