Electrostatic Discharge
Protection against electrostatic discharge (ESD) is essential while connecting,
inspecting, or cleaning connectors attached to a static-sensitive circuit (such
as those found in test sets).
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. Devices such as calibration components
and devices under test (DUT), can also carry an electrostatic charge. To
prevent damage to the test set, components, and devices:
— Al ways wear a grounded wrist strap having a 1 ΜΩ resistor in series with it
— Al ways use a grounded antistatic mat in front of your test equipment.
— Al ways wear a heel strap when working in an area with a conductive floor.
— Al ways ground yourself before you clean, inspect, or make a connection to

when handling components and devices or when making connections to
the test set.
If you are uncertain about the conductivity of your floor, wear a heel strap.
a static-sensitive device or test port. You can, for example, grasp the
grounded outer shell of the test port or cable connector briefly.
connection to the analyzer test port or other static-sensitive device. This
can be done as follows:
1. Connect a short (from your calibration kit) 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.
4. Remove the short from the cable.
