7 Reinstall the spring into the groove provided in the crystal cavity.
8 Determine if the retention force is acceptable and that the wire does not impede
crystal insertion. If needed, repeat the adjustment procedure.
4.3.4 Lubricating the Clamping Mechanism
If operation is impaired, lubricate moving parts with molybdenum disulfide (PN
750-191-G1), provided with each shuttered sensor, or graphite (PN 009-175), if
appropriate for the process.
The clamping mechanism may need to be lubricated on both shuttered and
non-shuttered UHV Bakeable Sensors (see
Figure 4-6 ).
Figure 4-6 Lubricating the clamping mechanism
4.3.5 Lubricating the Shutter Module
The shutter module should be lubricated approximately every 2000 strokes at
areas specified as shown in
Figure 4-7 . Failure to lubricate the shutter module may
significantly reduce life of operation or cause assembly to become inoperative.
For lubrication, use molybdenum disulfide (PN 750-191-G1), provided with each
shuttered sensor, or use graphite (PN 009-175), if appropriate for the process.
Apply molybdenum
disulfide or graphite
to the inside of the
slots in the clamping
mechanism.
