ESD Prevention
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.
