Safety and Regulatory Information
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 M  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
instrument 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.
