Leveling Head Connections
W
Warning
To prevent hazardous RF transmissions and equipment
damage, read and follow the instructions in Chapter 3 before
connecting a Leveling Head to the Instrument or to a UUT.
Instructions for connecting a Leveling Head to the Instrument and to a unit under test
(UUT) are given in Chapter 3, Local Operation . Do not attempt to connect a Leveling
Head before reading all of the Cautions and Warnings, contained in these instructions.
Installing the Instrument in an Equipment Rack
The Instrument is suitable for both bench-top and rack-mounted operation. A Rack
Mount Slide Kit is available as an accessory. Instructions for installing the kit are
supplied with the kit.
Cooling Considerations
Two internal fans maintain the operating temperature of the Instrument at a safe level. For bench-
top operation, these fans do a good job of temperature control without any attention other than
routine cleaning of the filter as described in Chapter 7,
Maintenance . However, when mounting
and using the Instrument in other situations (for example, in an equipment rack) additional
attention may be required to ensure that the instrument is able to maintain a normal operating
temperature and does not overheat.
W
Warning
To avoid fire hazard and to ensure that the instrument does not
exceed its normal operating temperature observe the following
warnings:
•
During normal operation, keep the Instrument covers
securely in place. Excessive air leaks can interrupt and
redirect the flow of cooling air from internal components.
•
When mounting the Instrument in an enclosed equipment
rack, provide adequate ventilation and airflow within the
rack. Pay particular attention to ensure adequate and proper
use of exhaust fans, louvers, equipment spacing, free-
flowing and isolated intake and exhaust ports.
Use baffles, if necessary, to isolate intake air from exhaust
air. Baffles can help draw and direct cooling air through the
equipment rack. The best placement of the baffles depends
on the airflow patterns within the rack. If baffles are
necessary, experiment with different arrangements. y
Cleaning the Instrument
For general cleaning, wipe the Instrument with a soft cloth dampened with water or a
non-abrasive mild cleaning solution that does not harm plastics.
W
Caution
To prevent damage to the Instrument, do not use aromatic
hydrocarbons or chlorinated solvents for cleaning. They can
damage the materials used in the Instrument.
