    Use, Maintenance, and Care of the Devices Electrostatic Discharge Electrostatic Discharge Protection against electrostatic discharge (ESD) is essential while connecting, inspecting, or cleaning connectors attached to a static-sensitive circuit (such as those found in test sets). Static electricity can build up on your body and can easily damage sensitive internal circuit elements when discharged.

  • Page 29: Visual Inspection

    Use, Maintenance, and Care of the Devices Visual Inspection Visual Inspection Visual inspection and, if necessary, cleaning should be done every time a connection is made. Inspect mating surfaces for dirt, dust, foreign particles, or scratches, which can degrade device performance. A damaged mating surface can damage any good surface connected to it.

  • Page 30: Cleaning The Mating Plane Surfaces

    Use, Maintenance, and Care of the Devices Cleaning the Mating Plane Surfaces Cleaning the Mating Plane Surfaces 1. Use Compressed Air or Nitrogen WARNING Always use protective eyewear when using compressed air or nitrogen. Use compressed air (or nitrogen) to loosen particles on the mating plane surfaces. Clean air cannot damage a device or leave particles or residues behind.

  • Page 31: Connections

    Use, Maintenance, and Care of the Devices Connections Connections Good connections require a skilled operator. Slight errors in operator technique can have a significant effect on measurements and measurement uncertainties. The most common cause of measurement error is poor connections. The following procedures illustrate how to make good connections.

    Use, Maintenance, and Care of the Devices Connections Tightening a Flange Connection NOTE The best connection has symmetrical pressure applied as you gradually tighten the screws. 1. In an “X” pattern (for equal compression), tighten all four screws using a hex ball driver. Do not over-tighten.

  • Page 35: Handling And Storage

    Use, Maintenance, and Care of the Devices Handling and Storage Handling and Storage • Install the protective end caps and store the calibration devices in the foam-lined storage case when not in use. • Never store devices loose in a box, or in a desk or bench drawer. This is the most common cause of device damage during storage.
