4 Operating the analyzer
4.1 Introduction
This section describes the normal operation of the analyzer and how to use the display
controller located on the front panel of the analyzer.
NOTICE
The gas concentrations shown in the following screenshots may be different from those shown
in your particular analyzer. The screenshots indicate the functionality of the software, which is
the same regardless of the gases or gas concentrations being measured.
4.2 Normal operation
The analyzer is designed for long term continuous operation, and therefore its normal
state is to be switched on and performing gas measurements. The analyzer is usually only
switched off for maintenance. The shutdown procedure used to switch off the analyzer is
described in
Chapter 8 of this manual.
Provided that the start-up procedure described in Chapter 3 has been followed, the
analyzer does not require any human intervention during normal operation other than
occasional calibration checks.
During normal operation, either the Gas Sensor Main screen ( Figure 4-1 ) or the Pressure and
Temperature screen ( Figure 4-2 ) is shown on the display controller. To toggle between
these two screens, press .
