Sensor Installation
As a general rule the sensor head should not be installed closer than 10 inches to the evaporation
source. This minimum distance will generally provide adequate measurement sensitivity while reducing
the possibility of the source spattering small particles onto the sensor. Even small particles hitting the
crystal surface may cause the crystal to become unstable or stop oscillating completely.
The sensor should be shielded from the evaporant source by a shutter or other means when
evaporant material is being initially conditioned or outgassed.
