Cooling Considerations

Damage caused by overheating can occur if the area around the
air intake or exhaust exit is restricted, the intake air is too
warm, or the air filter becomes clogged.
An important feature of the Product is its internal cooling system. Baffles direct
cool air from the fans throughout the chassis to dissipate heat during operation.
Maintain the coolest possible internal temperature to ensure the accuracy and
dependability of all internal parts of the Product.
The area around the air filter (power-switch side of the chassis) must be at least
7.5 cm (3 in) from nearby walls or rack enclosures. The exhaust perforations on
the rear of the Product must be clear of obstructions for 7.5 cm (3 in). Obstructed
airflow degrades Product performance.
To lengthen the life of the Product and ensure its performance:

Environmental and Input Requirements

For full accuracy, the Product must be used in an ambient temperature within
±5 °C of the temperature of the last calibration.
To operate the Product outside the specified temperature range, see the
temperature coefficients specifications. See Specifications.
To prevent possible electrical shock, fire, or personal injury,
limit voltage sources connected to the Product to ≤1050 V dc or
rms ac, and ≤200 mA. Do not connect voltages that have high-
energy transients.
6
Keep the air filter at least 7.5 cm (3 in) from nearby walls or rack enclosures.
See Rear-Panel Features.
Make sure that the exhaust perforations on the rear of the Product are
unobstructed.
Do not direct exhaust from another instrument into the air inlet of the Product.
Air entering the Product must be room temperature.
Vacuum the air inlet and outlet areas every 30 days or more frequently if the
Product is operated in a dusty environment.
