When the analyzer is switched on, at the end of the startup procedure, the Gas Sensor Main
screen ( Figure 4-7 ) appears. The Gas Sensor Main screen is the screen that is normally
displayed.
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.
Gas Sensor Main screen Figure 4-7:
The Gas Sensor Main screen displays the gas concentration measurements obtained by the
analyzer. In the example shown in Figure 4-7 , the gases ammonia (NH
3
), water (H
2
O),
carbon monoxide (CO), and formaldehyde (H
2
CO) are being measured, and for each gas,
the concentration detected is in parts per million (ppm).
At the end of the startup procedure, the gas measurements initially appear as 0.00 until
the first readings are taken. After a few seconds, the initial gas concentrations are
displayed.
The Gas Sensor Main screen also shows the status of the analyzer. In the example shown in
Figure 4-7 , the instrument is Running and OK (i.e., no faults have been identified).
If a fault is identified, ? is displayed; if maintenance is required, is displayed.
