[5] Place the screws (3) in the PET holder (4).
[6] Place the PET holder (4) on the two guides
(5) on the back of the laser receptacle (6)
being careful of maintaining the PET holder
higher on the laser side than on the back side.
[7] Once the holder (4) is engaged in the guides,
push it down until contact with the gilded ce -
ramic pads of the la ser is established.
[8] Screw the PET holder (4) to the receptacle
(6).
[9] Verify that the contact is established by
measuring with an ohm meter on the LLH100
low impedance plug.
Note: For reproducible measurement be care-
ful of measuring with the positive probe on the
+ LLH100 connect ion.
Note: If the contact is bad, adjust the plas-
tic screws (7) at the pressing end of the PET
holder (4).
[10] Place a dry desiccant bag close to the
low impedance line plug. Only applicable if
desiccation is needed and the lasers ha s been
shipped with a desiccant bag.
Note: This operation is preferably performed
in a gloves box under dry nitrogen atmosphere
if the ambient atmosphere is humid (this is
not necessary under normal conditions 50-60%
humidity).
