components are prevented from building static electric charges themselves.
This does not prevent discharges from static fields built up on other things,
like you and your clothing, from discharging through the instrument and
damaging it.
14.4. Basic Principles of Static Control
It is impossible to stop the creation of instantaneous static electric charges. It is not,
however difficult to prevent those charges from building to dangerous levels or prevent
damage due to electro-static discharge from occurring.
14.4.1. General Rules
Only handle or work on all electronic assemblies at a properly set up ESD station. Setting
up an ESD safe workstation need not be complicated. A protective mat properly tied to
ground and a wrist strap are all that is needed to create a basic anti-ESD workstation
(refer to figure 12-2).

Figure 14-2: Basic anti-ESD Work Station
For technicians that work in the field, special lightweight and portable anti-ESD kits are
available from most suppliers of ESD protection gear. These include everything needed
to create a temporary anti-ESD work area anywhere.
 Always wear an Anti-ESD wrist strap when working on the electronic
assemblies of your analyzer. An anti-ESD wrist strap keeps the person
wearing it at or near the same potential as other grounded objects in the work
area and allows static charges to dissipate before they can build to dangerous
levels. Anti-ESD wrist straps terminated with alligator clips are available for
use in work areas where there is no available grounded plug.
Also, anti-ESD wrist straps include a current limiting resistor (usually around one
meg-ohm) that protects you should you accidentally short yourself to the
instrument’s power supply.
 Simply touching a grounded piece of metal is insufficient. While this may
temporarily bleed off static charges present at the time, once you stop
touching the grounded metal new static charges will immediately begin to re-
build. In some conditions, a charge large enough to damage a component
can rebuild in just a few seconds.
 Always store sensitive components and assemblies in anti-ESD storage
bags or bins: Even when you are not working on them, store all devices and
assemblies in a closed anti-Static bag or bin. This will prevent induced
