Electrostatic Discharge
Electrostatic Discharge
Static electricity builds up on the body and on tools (including calibration
components and devices under test). When static electricity is accidentally
discharged, sensitive circuit elements can be damaged.
Circuit elements within a device can be damaged in this way from outside
the device (for example, through accidental contact with the center
conductor of a connector). Even a discharge that is too small to be felt can
cause circuit damage.
CAUTION Protection against electrostatic discharge (ESD) is essential while
connecting, cleaning, or inspecting connectors attached to a static–sensitive
circuit (such as those found in test sets). Protective measures appropriate to
the 8510XF are described below).
• Always have a grounded anti-static mat in front of your test equipment,
and wear a grounded wrist strap attached to it.
• 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 briefly to discharge static from your
body.)
• Discharge static electricity from a device before connecting it: touch the
device briefly (through a resistor of at least 1 MΩ) to either the outer
shell of the test port or to another exposed ground. This discharges static
electricity and protects test equipment circuitry.
