Electrostatic Discharge Information
Electrostatic discharge (ESD) can damage or destroy electronic components. Therefore,
all work performed on assemblies consisting of electronic components should be done at a
static-safe work station.
Figure 1-4 shows an example of a static-safe work station. Two types of ESD protection are
shown: (a) conductive table mat and wrist strap combination, and (b) conductive oor mat
and heel strap combination. The two types must be used together to ensure adequate ESD
protection. Refer to Table 1-1 for a list of static-safe accessories and their part numbers.
Figure 1-4. Static-Safe Work Station
Reducing ESD Damage
Below are suggestions that may help reduce the amount of ESD damage that occurs during
testing and servicing instruments
.
PC Board Assemblies and Electronic Components
Handle these items at a static-safe work station.
Store or transport these items in static-shielding containers
.
1-8 General Information

Caution
Do not use erasers to clean the edge-connector contacts. Erasers generate static
electricity and degrade the electrical quality of the contacts by removing the
thin gold plating.
Do not use paper of any kind to clean the edge-connector contacts.Paper
or lint particles left on the contact surface can cause intermittent electrical
connections.
Do not touch the edge-connector contacts or trace surfaces with bare hands.
Always handle board assemblies by the edges.
PC board assembly edge-connector contacts may be cleaned by using a lint-free cloth with a
solution of 80% electronics-grade isopropyl alcohol and 20% deionized water. This procedure
should be performed at a static-safe work station.
Test Equipment
Before connecting any coaxial cable to an instrument connector for the rst time each day,
momentarily short the center and outer conductors of the cable together.
Caution
Do
not
short the coaxial cable from the external power pack. Instrument
damage can result.
P
ersonnel should be grounded with aresistor-isolated wrist strap before touching the center
pin of any connector and before removing any assembly from the instrument.
Be sure that all instruments are properly earth-grounded to prevent buildup of static charge
