RSH-600 Operating Manual

Chapter 2
Installation 

CAUTION

During installation, special care must be taken to protect 
the barrel surface from being damaged. Scratches or 
gouges may prevent RSH-600 from forming a good 
vacuum seal to the O-ring. 

Successful operation of any crystal sensor depends on proper placement, 
compatibility of its construction with its operating environment and connection to 
proper utilities.

CAUTION

RSH-600 must be clean and grease free when installed in 
the vacuum chamber. The sensor must be handled while 
wearing clean nylon gloves. If parts do become 
contaminated, clean them thoroughly using a suitable 
solvent to avoid outgassing and excessive peeling of 
deposition material from the sensor surfaces.
