Use, Maintenance, and Care of the Devices
Electrostatic Discharge
Protection against ESD (electrostatic discharge) 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 (DUTs), can also carry an electrostatic charge. To
prevent damage to the test set, components, and devices:
—
always
wear a grounded wrist strap having a 1 M
resistor in series with
it when handling components and devices or when making connections
to the test set.
—
always
use a grounded, conductive table mat while making connections.
—
always
wear a heel strap 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 (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.
