a. Loosen the knurled nut that fixes the photomultiplier assembly and remove it from
the detector body.
CAUTION The photomultiplier tube could damage if exposed to ambient light with the
excitation voltage On. Make sure the power supply has been switched off before
disconnecting the tube from the detector body.
ATTENTION Le tube photomultiplicateur pourrait être endommagé en cas d'exposition à
la lumière ambiante alors que la tension d'excitation est activée. Assurez-vous que
l'alimentation a été coupée avant de débrancher le tube du corps du détecteur.
b. Remove the interferential filter from its housing, handling it very gently.
Keep it using a clean paper towel. See
Figure 171. Interferential Filter Removal
