ENVIRONMENTAL REQUIREMENTS

1-1. Atmospheric Pressure Limits (Storage and Operational)
(operation, storage and transportation*)
* - During transportation a pressurized environment must be used to maintain the atmospheric
pressure limits.
1-2. Preventing Thermal Shock to the Detector
To prevent thermal shock to the detector, the ambient tempertaure gradient must not exceed the values
as specified below.
Temperature range
Ambient temperature
gradient must not
exceed
1-3. Storage Requirements - temperature and humidity
1-3-1. General requirements
- The system includes a detector assembly in its casing, which is sensitive to changes in tempera-
ture and humidity, and is water-cooled when in use.
- The specified storage requirements assume that the all the equipment remains in its packaging,
including the protection for the detector.
1-3-2. Before installation - short term
For short-term storage (less than 5 days), refer to the storage requirements table below.
1-3-3. Before installation - long term
For long-term storage (more than 5 days), it is recommended that the detector assembly is kept in an
area with relatively dry and low temperature, or area with air conditioning. For example, relative humidity
less than 50%.
