    Use, Maintenance, and Care of the Devices Gaging Connectors Gaging Connectors The gages available from Agilent Technologies are intended for preventive maintenance and troubleshooting purposes only. See Table 6-1 on page 6-2 for part number information. They are effective in detecting excessive center conductor protrusion or recession, and conductor damage on DUTs, test accessories, and the calibration kit devices.

  • Page 27: Reading The Connector Gage

    If the center conductor protrudes, the indicator will move clockwise to indicate the amount of protrusion, which is read as a positive value. Refer to “Pin Depth” on page 2-3 for definitions of protrusion and recession. Figure 3-2 Reading the Connector Gage 85050C...
