Assembly and Installation
2.2.1
Assembly of JUNIOR-PAM fluorometer
Unpack fiber optics. Carefully insert the fiber end with the silicone
sleeve into the fiber port of the JUNIOR-PAM until silicone sleeve and
fiber port get in contact. Frequently, the fiber encounters a resistance
during insertion: if this is the case, remove the fiber, carefully straighten
the fiber by hand, and insert again. Do not forcible overcome the resis-
tance. Finger-tighten the plastic screw of the light guide port.
Insert free end of light fiber into top of the fiber port of the magnetic
leaf clip (Fig. 3) until the fiber tip is flush with the sample-facing sur-
face of the fiber port. Finger-tighten the plastic screw of the magnetic
leaf clip. Now, the distance between fiber tip and the surface of a sample
held by the magnetic leaf clip 1mm.
Connect type B plug of the USB cable with the JUNIOR-PAM, and type
A plug with a computer running with Microsoft Windows 2000, XP or
Vista operating systems. At this point; the top side signal LED of the
JUNIOR-PAM should flash green at a frequency of 1 Hz, and, at the end
of the fiber, blue measuring light should be visible.
