Lift the Solid State Detector up and swing it slightly to the side away from the sample area. Swing the
locking arm back so that it rests against the side of the Solid State Detector, holding it in place.

Check the pin shape. The slightly pointy shape of the pin on the left in the image below can dent or even
penetrate the sample. The pin shown on the right has a flat tip, allowing for good contact with the sample.

5
Use alcohol and very fine sandpaper to clean the tip of each pin. Slowly and carefully smooth out any
rough edges or points.
6
Put the Detector back in place, locking the locking arm.
Clean the Light Pipe Assembly
NOTE
: The sample is directly above the Xenon pulse distribution light pipe. It is therefore important to
protect the light pipe from dirt and possible damage. Periodic cleaning of the top surface of the light pipe is
recommended. If dirt or other substances build up on it, it will adversely affect the signal for the tempera-
ture rise of the top surface of the sample, and yield erroneous results.
1
Disconnect the LN lines.
2
Lift the EM module from the top of DXF module. The EM can simply be moved a few inches back,
remaining on top of the DXF.
3
Tilt the EM module at a 90° angle, allowing it to rest on its front so that you can access the light pipe
