Electrostatic Discharge Information

Electrostatic discharge (ESD) can damage or destroy electronic components. Therefore, observe the following precautions:

Be sure

that

all instruments are properly earth-grounded to prevent

buildup of static charge.

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.

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 work station. 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

Table
