29 . To verify that the sensor gasket was inserted properly:
a. Plug the inlet with your finger.
b. Verify that the GX-6000 goes into low flow alarm. If the GX-6000 does not go
into low flow alarm, turn the instrument off and attempt to seat the sensor gasket
again.
30 . Calibrate the PID sensor as described in “Chapter 4: Calibration Mode” on page 69.
Replacing the PID Sensor’s Lamp
If cleaning the PID lamp does not resolve any calibration problems you may be having,
the lamp may need to be replaced.
Ordering the Correct Replacement Lamp
It’s important to order the correct replacement lamp for your PID sensor.
1 . Look at the label(s) on the side of your PID sensor. Some sensors only have a label
that says “PIS-001” or “PIS-002”. Other sensors have a label that says “PIS-001” or
“PIS-002” and another RKI part number label that says “PID-001L” or “PID-002L”.
2 . See the table below for replacement lamp part numbers based on your sensor’s
label(s).
Steps to Replace the Lamp
Perform the following procedure to replace the PID 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.
