Electrostatic Discharge Protection
Protection against electrostatic discharge (ESD) is essential while removing assemblies from or
connecting cables to the system components. 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, connected to a grounded conductive table mat, having a
1 M
resisto
r in series with it, when handling components and assemblies or when 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 and remove the short from the cable.
