Appendix I: 11.7 eV PID Sensor • 235
Measuring Mode
The 11.7 eV PID sensor detects VOCs in the 0-1000 ppm range. In the 0-100 ppm range,
the reading increment is 0.1 ppm. In the 100-1000 ppm range, the reading increment is
1 ppm. See “Measuring Mode, Normal Operation” on page 35 for a complete description
of Measuring Mode.
Turning Off a GX-6000 with an 11.7 eV PID Sensor
Eliminating as much moisture from the flow system as possible before turning off the
GX-6000 will help prolong the life of the 11.7 eV PID sensor’s lamp.
1 . Remove the tubing from one end of the dehumidifier filter. It does not matter which
end you remove. The dehumidifier filter does not have a flow direction. Do not use
the dehumidifier filter if it appears wet.
2 . Connect the tubing to the GX-6000’s inlet.
3 . Allow the GX-6000 to draw through the filter for 30 seconds.
4 . Turn off the GX-6000.
5 . Remove the tubing from the inlet fitting and immediately plug the inlet fitting with
the black rubber cap.
