Sensors Setup
The Sensors dialog box displays configuration parameters for optional
sensors used by the analyzer. The Sensor1 screen is reserved for infrared
(IR) sensors used to measure CO
2
and/or HC gases. Sensor2 screen is
reserved for thermal conductivity (TC) sensors used to measure H
2
gas.
Sensor3 screen is reserved for IR sensors used to measure HC gases or TC
sensors used to measure H
2
gas.
The parameters displayed here are the results of settings in the analyzer.
Choose the corresponding Sensor tab for the sensor screen you wish to
view or configure.
Hazardous Locations
To comply with the requirements of the hazardous location certifica-
tion for the sensors, do not operate these sensors in a hazardous loca-
tion at a pressure greater than 825 mmHg (1.1 BAR or 16 PSIA).
The Sensor1, Sensor2, and Sensor3 tabs display information that is
common to all three sensors; however information that applies only to
