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:
— al ways have a grounded, conductive table mat in front of your test
— al ways wear a grounded wrist strap with grounding cord, connected to a
— al ways wear a heel strap (9300-1126) when working in an area with 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.
