Model 3585A
2·8. Storage and Shipping Environment
The 3585A should be stored in a clean, dry environment. The following environmental
limitations apply to both storage and shipment :
Temperature
Relative Humidity
Altitude
In high-humidity environments, the instrument must be protected from temperature varia
tions that could cause internal condensation.
2·9. Cooling System
The 3585A uses a forced-air cooling system to maintain the proper internal operating
temperature. The cooling fan is located on the rear panel. Air, drawn through the rear-panel
fan filter, is circulated through the instrument and exhausted through holes in the side
panels. The instrument should be mounted to permit as much air circulation as possible,
with at least one inch of clearance at the rear and on each side. The filter for the cooling fan
should be removed and cleaned at least once every 30 days . To clean the fan filter, simply
flush it with soapy water, rinse and then air dry.
2· 1 0. Thermal Cutout
The 3585A is equipped with a thermal cutout switch which automatically disables the power
supplies when the internal temperature exceeds + 65°C (external termperature approximate
ly + 55°C). To reset the thermal cutout, set the LINE switch to OFF, allow time for the in
strument to cool and then set the LINE switch to ON. (The thermal cutout will not reset
automatically; the LINE switch must be turned off and then back on.) If a thermal cutout
occurs, check for fan stoppage, clogged fan ports and other conditions that could obstruct
air flow or cause excessive heating.
2·1 1 . INSTALLATION
2·1 2. Bench Mounting
The 3585A is shipped with plastic feet attached to the bottom panel, ready for use as a bench
instrument. The feet are shaped to make full-width modular instruments self align when they
are staked. Because of its weight, the 3585A is not equipped with a tilt stand. It is recom
mend that a Front Handle Kit (Option 907, -hp- Part No . 506 1 -0091 ) be installed for ease of
handling the instrument on the bench.
- 40°C to + 75°C ( - 40°F to + 1 58°F)
