Environmental considerations
Shipping and storage environment
To avoid possible damage or deterioration, the 4200-SCS should be shipped and stored within the
following environmental limits:
• Temperature: -10 °C to +60 °C
• Relative humidity: 5 % to 90 %, non-condensing
Operating environment
Temperature and humidity
The 4200-SCS should be operated within the following environmental limits:
• Temperature: +15 °C to +40 °C
• Relative humidity: 5 % to 80 %, non-condensing
NOTE SMU and preamp accuracy specifications are based on operation at 23 °C ±5 °C and
between 5 % and 60 % relative humidity. See the product specifications for additional
temperature and humidity derating factors outside these ranges.
Proper ventilation
To avoid overheating, the 4200-SCS should be operated in an area with proper ventilation. Allow
at least eight inches of clearance at the back of the mainframe to assure sufficient airflow.
CAUTION
To prevent damaging temperatures and other harmful environmental
conditions that could degrade specified performance, follow these
precautions:
•
Keep the venting holes and fan free of dust, dirt, and contaminants, so that
the unit’s ability to dissipate heat is not impaired.
•
Keep the fan vents and cooling vents from becoming blocked.
•
Do not position any devices that force air (heated or unheated) adjacent to
the unit into cooling vents. This additional airflow could compromise
accuracy performance.
•
When rack mounting the unit, make sure there is adequate airflow around
the sides, bottom, and back to ensure proper cooling.
•
Rack mounting high-power dissipation equipment adjacent to the Model
4200-SCS could cause excessive heating to occur.
•
To ensure proper cooling in rack situations with convection cooling only,
place the hottest equipment (the, power supply) at the top of the rack.
Precision equipment, such as the 4200-SCS, should be placed as low as
possible in the rack where temperatures are the coolest.
•
Add spacer panels below the unit will help ensure adequate airflow.
