2-3. Service Information
Each 5725A Amplifier is warranted to the original purchaser for a period of one year
beginning on the date received. The warranty is located at the front of this manual.
Factory-authorized service and technical advice for the 5725A is available at Fluke
Service Centers. A complete list of service centers is available at www.fluke.com.
Warning
Servicing described in this manual is to be done by qualified
service personnel only. To avoid electrical shock, do not
service the 5725A unless you are qualified to do so.
The owner may choose to repair a 5725A using the troubleshooting information in
Section 7 to isolate a faulty module, then use the Module Exchange Program. Refer to
the Fluke catalog or contact a Service Center representative for the module exchange
procedure.
2-4. Placement and Rack Mounting
You can stack the 5725A on top of or below the 5700A Calibrator. (Choose the
configuration that provides the easiest access to the 5700A Calibrator controls.) Or, you
can mount the 5725A in a standard-width, 24-inch (61-cm) deep equipment rack. For
bench-top stacking, the 5725A is equipped with non-skid feet. To mount the 5725A in an
equipment rack, order the accessory 5725A Rack Mount Kit, Model Y5735. An
instruction sheet is packed with the kit.
Caution
Use only the rack mount slides included in the Y5735 kit. Rack
mount slides intended for other instruments can block the side
ventilation holes on the 5725A and cause overheating.
2-5. Cooling Considerations
Caution
Damage caused by overheating may occur if the area around
the air intake is restricted, the intake air is too warm, or the fan
filter becomes clogged.
Accuracy and dependability of all internal parts of the 5725A are enhanced by
maintaining the coolest possible internal temperature. By observing the following rules
you can lengthen the life of the 5725A:
• The area around the fan filter must be at least 3 inches from nearby walls or rack
enclosures.
• Exhaust perforations on the sides of the 5725A must be clear of obstructions. Most
of the heat exits from the side vents near the front.
• Air entering the instrument must be room temperature. Make sure that exhaust from
another instrument is not directed into the fan inlet.
• Clean the fan filter every 30 days, or more frequently if the 5725A is operated in a
dusty environment. (Instructions for cleaning the fan filter are in Section 6.)
