  • Page 17: Visual Inspection

    Use, Maintenance, and Care of the Cables Visual Inspection Visual Inspection Visual inspection and, if necessary, cleaning should be done every time a connection is made. Metal particles from the connector threads may fall onto the mating plane surface of the connector when it is disconnected. One connection made with a dirty or damaged connector can damage both connectors beyond repair.
  • Page 18 Use, Maintenance, and Care of the Cables Visual Inspection If a connector shows deep scratches or dents, particles clinging to the mating plane surfaces, or uneven wear, clean and inspect it again. Cables with damaged connectors should be repaired or discarded. Determine the cause of damage before connecting a new, undamaged connector in the same configuration.

    Use, Maintenance, and Care of the Cables Precision Slotless Connectors (3.5 mm) Precision Slotless Connectors (3.5 mm) The female 3.5 mm connectors in the cable sets are metrology-grade, precision slotless connectors (PSC). Precision slotless connectors are used to improve accuracy. A characteristic of metrology-grade connectors is directly traceability to national measurement standards through their well-defined mechanical dimensions.

    Use, Maintenance, and Care of the Cables Gaging Connectors Gaging Connectors The gages available from Keysight Technologies are intended for preventive Table 4-1 on page 3 maintenance and troubleshooting purposes only. (See part number information.) They are effective in detecting excessive center conductor protrusion or recession, and conductor damage on test cables and other accessories, DUTs, and calibration kit devices.

  • Page 23: Gaging Procedures

    Use, Maintenance, and Care of the Cables Gaging Connectors — Initially after every 100 connections, and after that as often as experience indicates. Gaging Procedures Gaging 3.5 mm Connectors Always hold a connector gage by the gage barrel, below the dial indicator. This gives the best stability, and improves measurement accuracy.
  • Page 24 Use, Maintenance, and Care of the Cables Gaging Connectors d. Read the gage indicator dial. Read only the black ± signs; not the red ± signs. For maximum accuracy, measure the connector a minimum of three times and take an average of the readings. After each measurement, rotate the gage a quarter-turn to reduce measurement variations that result from the gage or the connector face not being exactly perpendicular to the center axis.

    Use, Maintenance, and Care of the Cables Making Connections Figure 3-4 Using the Torque Wrench 3. Apply downward force perpendicular to the wrench handle. This applies torque to the connection through the wrench. Do not hold the wrench so tightly that you push the handle straight down along its length rather than pivoting it, otherwise you apply an unknown amount of torque.

    Use, Maintenance, and Care of the Cables Handling and Storage Handling and Storage — Install the protective end caps and store the cables in the foam-lined storage case when not in use. — Never store cables loose in a box, desk, or bench drawer. This is the most common cause of cable connector damage during storage.
