Electrostatic
Electrostatic discharge (ESD) can damage or destroy electronic
Discharge
components. Therefore, observe the following precautions:
Information
n Be sure that all instruments are properly earth-grounded to prevent
buildup of static charge.
n Before connecting any coaxial cable to an instrument connector for
the first time each day, momentarily short the center and outer
conductors of the cable together.
n Personnel should be grounded with a resistor-isolated wrist strap
before touching the center pin of any connector and before
removing any assembly from the instrument.
n When replacing the instrument’s battery (refer to Replacing the RF
Section Battery in this chapter), be sure to observe the following:
q Perform the work at a static-safe workstation. See Figure l-4.
q Store or transport PC boards only in static-shielding containers.
q Always handle board assemblies by the edges. Do not touch the
edge-connector contacts or trace surfaces with bare hands.
Figure l-4 shows an example of a static-safe workstation. Two types
of ESD protection are shown: a) conductive table mat and wrist strap
combination, and b) conductive floor mat and heel strap combination.
The two types must be used together to ensure adequate ESD
protection. Refer to nble l-l for a list of static-safe accessories and
their part numbers.
