Performance Checks and Readjustments

Observe the following precautions to avoid damage:

1.Minimize handling of static-sensitive components.

2.Transport and store static-sensitive components or assemblies in their original containers, on a metal rail, or on conductive foam. Label any package that contains static-sensitive components or assemblies.

3.Discharge the static voltage from your body, by wearing a wrist grounding strap, while handling these components. Servicing static-sensitive assem- blies or components should be done only at a static-free work station by qualified personnel.

4.Nothing capable of generating or holding a static charge should be allowed on the work station surface.

5.Keep the component leads shorted together whenever possible.

6.Pick up the components by the body, never by the leads.

7.Do not slide the components over any surface.

8.Avoid handling components in areas that have a floor or work surface covering capable of generating a static charge.

9.Use a soldering iron that is connected to earth ground.

10.Use only special antistatic, suction, or wick-type desoldering tools.

Instrument performance should be checked after each 2000 hours of operation, or every 12 months, if used intermittently. This will help to ensure maximum performance and assist in locating defects that may not be apparent during regular operation. The Performance Check Procedure and the Adjustment Procedure are in Section 5.

TROUBLESHOOTING

The 1705A is equipped with a microprocessor and, as with all of the new Tektronix monitors, it is capable of some power-up and off-line diagnostics. A thorough understanding of the information available in the diagnostic routines will assist in isolating problems and speed repairs.
