Mandatory Specifications for the system environment
Rated for use in a Pollution Degree 1 Installation Category environment (laboratory or
clean industrial environment).
•
Operating temperature:
5°C to 25°C.
•
Storage temperature:
0°C to 40°C.
•
Maximum humidity:
90% See NOTE 1.
•
Minimum humidity:
10% See NOTE 2.
•
Electrostatic build-up:
Low static environment. See NOTE 2.
•
Ambient light level:
300 lux minimum.
NOTE 1: High humidity will have a progressively significant effect on system
performance. At humidity greater than 50%, the rate of chamber pump-
down after venting the chamber will be affected significantly, and at
humidity greater than 65%, the rate of chamber pump-down may not meet
system specifications.
NOTE 2: Low humidity will introduce a risk of electrostatic build-up, with subsequent
discharge to the system producing a malfunction or damage. The systems
are tested to EN60801-2, severity level 3. We recommend the use of an
environment, which protects against electrostatic build-up, and extra
precautions will be necessary at low humidity.
