Air Temperature Requirements
Table 5-1 summarizes the temperature and cooling requirements for the system.
Air Temperature Specifications
The i3070 test system is designed to operate uninterrupted in an area where the air
temperature is stable and in the range from 0°C to 40°C (32°F to 104°F), as
measured at the tester-to-fixture interface.
The system has a built-in temperature sensor inside the testhead, located on the
ASRU card. This sensor constantly monitors the temperature of the air that has
been drawn through the testhead after it cools the system components. If the
temperature sensor finds that the air temperature inside the testhead has changed
±5°C (±9°F) since the last time the system ran AutoAdjust All, it will run AutoAdjust
All again. Therefore, to ensure uninterrupted use, it is important that the ambient
room temperature remain reasonably stable.
If the sensor finds that the air temperature inside the system is too high, the system
will shut down; typically, the over-temperature shutdown point is 55°C (131°F). See
Cooling Requirements for information on air conditioning requirements.
Table 5-1 Temperature and humidity ranges for operation and storage
Operating Temperature Operating Humidity Storage Temperature
Testhead
0°C to 40°C (32°F to 104°F)
5% to 80% non-condensing -40°C to 70°C (-40°F to 158°F)
Controller 20% to 80% non-condensing -40°C to 65°C (-40°F to 149°F)
The air temperature inside the system is not considered
stable until the system has been powered for at least 30
minutes.
