133 • PID Sensor Maintenance GX-6000 Operator’s Manual
Replacing the PID Sensor’s Electrode Stack
The electrode stack can last for the life of the PID sensor if the GX-6000 is
used in a very clean, controlled environment. When used in a heavily
contaminated or dirty environment, the electrode stack may only last a
month. A contaminated electrode stack will cause a drop in sensitivity which
can cause problems calibrating the PID channel. The electrode stack should
be replaced if the PID sensor shows signs of contamination even after
cleaning or replacing the lamp.
NOTE: Do not touch the new lamp window (the flat end) with your fingers
as this may contaminate the window with finger oil.
1 . Verify that the GX-6000 is off.
2 . Use a small Phillips screwdriver to unscrew the four screws holding the
flow chamber to the rest of the GX-6000’s case.
3 . Grasp the sides of the flow chamber and lift it away from the rest of the
case. The screws are captive screws and will not come out of the flow
chamber.
4 . Gently pull up the edges of the sensor gasket to loosen it from its
connections. Be sure not to lose any of the filters that are in it. The
sensors will be exposed.
5 . Locate the PID sensor.
6 . Grasp the sensor firmly and pull it out of its socket.
7 . Place the PID sensor face down on a flat clean working surface.
NOTE: At this point it is recommended that the finger cots be used on the
fingers handling the lamp. Finger cots are included with the lamp
cleaning kit.
