When To Gage Connectors; Reading The Connector Gage - Keysight Technologies 85032B User's And Service Manual

When to Gage Connectors

Gage a connector at the following times:
• Prior to using a device for the first time: record the pin depth measurement so that it can be compared
with future readings. (It will serve as a good troubleshooting tool when you suspect damage may have
occurred to the device.)
• If either visual inspection or electrical performance suggests that the connector interface may be out of
typical range (due to wear or damage, for example).
• If a calibration device is used by someone else or on another system or piece of equipment.
• Initially after every 100 connections, and after that as often as experience indicates.

Reading the Connector Gage

The gage dial is divided into increments of 0.0001 inch and major divisions of 0.001 inch (see
For each revolution of the large dial, the smaller dial indicates a change of 0.01 inch. Use the small dial as
the indicator of multiples of 0.01 inch. In most connector measuring applications, this value will be zero.
When making a measurement, the gage dial indicator will travel in one of two directions. If the center
conductor is recessed from the zero reference plane, the indicator will move counterclockwise to indicate
the amount of recession, which is read as a negative value. 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
Depth on page 2-3 for definitions of protrusion and recession.
