MAINTENANCE AND TROUBLESHOOTING

2.3 REQUIRED TEST EQUIPMENT

The test equipment required to conduct performance verification procedures and
troubleshooting is listed in Table 2-1. Substitute equipment may be employed provided
said equipment meets the accuracy specifications of the equipment specified.
Description
Digital Multimeter (DMM)
Oscilloscope
Computer with IEEE-488.2 Interface
WARNING
Remove power when performing maintenance on the unit. Failure to
comply can result in serious electrical shock to individuals coming in
contact with live voltages at exposed terminals when the unit is
energized. Once the unit is de-energized, a wait period of at least 5
minutes should be observed to allow internal capacitors to discharge.

2.4 PERIODIC MAINTENANCE

Other than calibration and cleaning, no periodic maintenance is required on TW
systems. Calibration is discussed in Section 3 of this manual. Periodic cleaning is
required to insure that dust build-up within the chassis does not restrict airflow through
the modules leading to overheating of the system. A strong vacuum cleaner may be
used to remove dust from the various assemblies within the TW chassis. Compressed
air is not recommended.
