Note During the extraction of the photomultiplier tube from its holder, the PMT
telescopic centering sleeve assemble could remain inside the holder or get out of it.
In this case, before reinserting the photomultiplier tube into its holder, the PMT
telescopic centering sleeve assemble must be correctly repositioned as described at the
step 9.
8. Replace the defective photomultiplier tube.
Note Wear clean, lint- and powder-free gloves when you handle the photomultiplier
tube and void exposing it to light.
a. Carefully extract the photomultiplier tube from its connector. See
