1.4. Sensor Configuration Notes
It is important to note that although the IEQ Chek™ will accommodate seven sensors
(and five of those sensor locations are plug and play for gas sensors), there are
sensor placement considerations.
Either of the two front sensor locations will accommodate an infrared CO
2
sensor, PID
sensor, or catalytic combustible (flammable) gas sensor.
Of the five plug-and-play sensor locations, three are for electrochemical sensors. If
the user selects an oxygen (O
2
) sensor, it must be fitted to a specific sensor location
(rear center position, determined by looking at the front of the instrument). If the user
selects a nitric oxide (NO), requiring electronic bias within the circuit, it must be fitted
to one specific sensor location (left rear position, determined by looking at the front of
the instrument). Two sensors requiring bias cannot be fitted in the same instrument at
the same time. Reference the photos on pages 23 and 24 for specific sensor
locations.
