If You Encounter a Problem If You Encounter a Problem If You Encounter a Problem If you have difficulty when installing or using the Agilent 8702D, check the following list of commonly encountered problems and troubleshooting procedures. Contact the nearest Agilent Technologies office for service, if necessary. A list of Agilent Technologies service offices is provided on page 7-8.
If You Encounter a Problem If the fan does not run WARNING The power cord is connected to internal capacitors that may remain live for 10 seconds after you disconnect the cord from the power supply. Figure 7-1. Line Fuse Removal and Replacement WARNING For continued protection against fire hazard, replace the fuse with the same type and rating. If the fan does not run 1 Switch the LINE power switch to the off position. 2 Check that the fan blades are not jammed or obstructed.
If You Encounter a Problem If there is no RF signal The “entry off” is enabled after you press the ENTRY OFF key. To return to normal entry mode, press any function key that has a numeric parameter associated with it. For example, START. ❒ Check that none of the keys are mechanically stuck. ❒ Check that the selected key is designed to accept data. For example, SCALE REF accepts data, but SYSTEM does not. ❒ Ensure that you are not attempting to enter a value that is greater than or less than its limit.
If You Encounter a Problem Returning the Instrument for Service Returning the Instrument for Service The instructions in this section show you how to properly return the instrument for repair or calibration. Always call the Agilent Technologies Instrument Support Center first to initiate service before returning your instrument to a service office. This ensures that the repair (or calibration) can be properly tracked and that your instrument will be returned to you as quickly as possible.
If You Encounter a Problem Returning the Instrument for Service information should be returned with the instrument. • Type of service required. • Date instrument was returned for repair. • Description of the problem: • Whether problem is constant or intermittent. • Whether instrument is temperature-sensitive. • Whether instrument is vibration-sensitive. • Instrument settings required to reproduce the problem. • Performance data. • Company name and return address.
If You Encounter a Problem Returning the Instrument for Service Sealed Air Corporation (Commerce, California 90001). Air Cap looks like a plastic sheet filled with air bubbles. Use the pink (antistatic) Air Cap™ to reduce static electricity. Wrapping the instrument several times in this material will protect the instrument and prevent it from moving in the carton. 4 Seal the carton with strong nylon adhesive tape. 5 Mark the carton “FRAGILE, HANDLE WITH CARE”. 6 Retain copies of all shipping papers.
