Sensor selection examples

The GX-9000 accepts up to six sensors. The GX-9000H accepts up to
five. Each of the three R sensors (R1 - R3) can be selected or unselected.
One sensor (or no sensors) can be selected from each box in the tablebelow for F sensors (F1 - 3).

Example 1: Four main gas types + 1
