VENTILATION REQUIREMENTS: When installing the product in a cabinet, the
convection into and out of the product must not be restricted. The ambient
temperature (outside the cabinet) must be less than the maximum operating
temperature of the product by 4
°
C for every 100 watts dissipated in the
cabinet. If the total power dissipated in the cabinet is greater than 800 watts,
then forced convection must be used.
C A U T I O N
Always use the three-prong ac power cord supplied with this instrument.
Failure to ensure adequate earth grounding by not using this cord may cause
instrument damage.
C A U T I O N
Do not
connect ac power until you have verified the line voltage is correct.
Damage to the equipment could result.
C A U T I O N
This instrument has autoranging line voltage input. Be sure the supply voltage
is within the specified range.
Measurement accuracy—it’s up to you!
Fiber-optic connectors are easily damaged when connected to dirty or damaged cables
and accessories. The Agilent 11982A front-panel OPTICAL OUT connector is no excep-
tion. When you use improper cleaning and handling techniques, you risk expensive
instrument repairs, damaged cables, and compromised measurements.
