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 50°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.
