UHV Bakeable Sensor Operating Manual
6
Replace the ceramic retainer. Initially orient it at an angle to displace the spring
wire segments in the crystal holder.
CAUTION
Do not use excessive force when handling the
Ceramic Retainer Assembly since breakage may occur.
Always use the crystal snatcher.
To prevent scratching the crystal electrode, do not rotate
the ceramic retainer after installation.
7
Release the crystal snatcher with a slight side-to-side rocking motion. Using the
backside of the crystal snatcher, push on the ceramic retainer to ensure it is
completely seated.
8
Reinstall the holder in the sensor body. Push the holder straight in making
certain that it is completely seated in the senor body, then latch the clamping
spring handle.
CAUTION
Never deposit material on a sensor unless the crystal
holder and crystal are installed. Material deposited on the
exposed sensor body assembly will cause either
complete failure to oscillate or lead to premature crystal
failure. Removing the deposited material requires
extensive rework and new components.
