Maintenance
This section contains information needed to perform periodic and corrective maintenance on the instrument.
Preventing ESD
Before servicing this product, read the General Safety Summary and the Service Safety Summary at the front of the manual, as well as the
following ESD information.
CAUTION: Electrostatic discharge (ESD) can damage any semiconductor component in this instrument.
When performing any service that requires internal access to the instrument, adhere to the following precautions to avoid damaging
internal modules and their components due to electrostatic discharge:
1. Minimize handling of static-sensitive circuit boards and components.
2. Transport and store static-sensitive modules in their static protected containers or on a metal rail. Label any package that contains
static-sensitive boards.
3. Discharge the static voltage from your body by wearing a grounded antistatic wrist strap while handling these modules.
4. Service static-sensitive modules only at a static-free work station.
5. Do not allow any items capable of generating or holding a static charge on the work station surface.
6. Handle circuit boards by the edges when possible.
7. Do not slide the circuit boards over any surface.
8. Avoid handling circuit boards in areas that have a floor or work-surface covering capable of generating a static charge.
Inspection and cleaning
Inspection and Cleaning describes how to inspect for dirt and damage. It also describes how to clean the exterior and interior of the
instrument. Inspection and cleaning are done as preventive maintenance. Preventive maintenance, when done regularly, may prevent
instrument malfunction and enhance its reliability.
Preventive maintenance consists of visually inspecting and cleaning the instrument and using general care when operating it.
How often to perform maintenance depends on the severity of the environment in which the instrument is used. A proper time to perform
preventive maintenance is just before instrument adjustment.
Exterior cleaning (other than display)
Clean the exterior surfaces of the chassis with a dry lint-free cloth or a soft-bristle brush. If any dirt remains, use a cloth or swab dipped in
a 75% isopropyl alcohol solution. Use a swab to clean narrow spaces around controls and connectors. Do not use abrasive compounds on
any part of the chassis that may damage the chassis.
Clean the On/Standby switch using a cleaning towel dampened with deionized water. Do not spray or wet the switch itself.
CAUTION: Avoid the use of chemical cleaning agents which might damage the plastics used in this instrument. Use only
deionized water when cleaning the front-panel buttons. Use a 75% isopropyl alcohol solution as a cleaner for cabinet parts. Before
using any other type of cleaner, consult your Tektronix Service Center or representative.
Inspection - Exterior. Inspect the outside of the instrument for damage, wear, and missing parts. Immediately repair defects that could
cause personal injury or lead to further damage to the instrument.
