Operating and Safety Precautions
Observe the following guidelines before connecting or operating your ECal module.
ESD Damage
Protection against electrostatic discharge (ESD) is important while handling and
operating your ECal module. Static electricity can build up on your body and can easily
damage sensitive components when discharged. Static discharges too small to be felt can
cause permanent damage to the unit. To prevent damage from ESD:
• Use a grounded antistatic mat in front of your test equipment and wear a grounded
wrist strap attached to it when handling or operating the ECal module.
• Wear a heel strap when working in an area with a conductive floor.
• Ground yourself before you clean, inspect, or make a connection to an ECal module.
You can, for example, grasp the grounded outer shell of the analyzer test port or cable
connector briefly.
• Avoid touching the center conductor of the test ports.
For more information about preventing ESD, see
Connector Care
Because connectors can become defective due to wear during normal use, all connectors
should be inspected and maintained to maximize their service life.
• Inspect the mating surface each time a connection is made. Metal particles from
connector threads often find their way onto the mating surface when a connection is
made or disconnected.
• Clean dirt and contamination from the connector mating surface and threads. This
simple step can extend the service life of the connector and improve the quality of your
calibration and measurements.
• Gage connectors periodically. This not only provides assurance of proper mechanical
tolerances, and thus connector performance, but can also indicate situations where the
potential for damage to another connector may exist.
You should apply connector care to all devices used in the measurement setup. For more
detailed information, see
CAUTION
ECal modules can be damaged if you apply excessive torque to the connectors.
