Electrostatic Discharge Protection
Electrostatic Discharge Protection
Protection against electrostatic discharge (ESD) is essential while removing assemblies from
or connecting cables to the instrument. Static electricity can build up on your body and can
easily damage sensitive internal circuit elements when discharged. Static discharges too
small to be felt can cause permanent damage. To prevent damage to the instrument:
•
always
have a grounded, conductive table mat in front of your test equipment.
•
always
wear a grounded wrist strap with grounding cord, connected to a grounded
conductive table mat, having a 1 MΩ resistor in series with it, when handling components and
assemblies or when making connections.
•
always
wear a heel strap (9300-1126) when working in an area with a conductive floor. If you
are uncertain about the conductivity of your floor, wear a heel strap.
•
always
ground yourself before you clean, inspect, or make a connection to a
static-sensitive device or test port. You can, for example, grasp the grounded outer shell of the
test port or cable connector briefly.
•
always
ground the center conductor of a test cable before making a connection to the
analyzer test port or other static-sensitive device. This can be done as follows:
1. Connect a short to one end of the cable to short the center conductor to the outer
conductor.
2. While wearing a grounded wrist strap, grasp the outer shell of the cable connector.
3. Connect the other end of the cable to the test port and remove the short from the cable.
