Service Information

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.)
