Gauging Devices
Gauging Devices
Gauges are intended for preventive maintenance and troubleshooting
purposes only. They are effective in detecting center conductor
protrusion or excessive recession. Using gauges can be effective in
preventing connector damage on devices-under-test (DUTs), test
accessories, and the ECal modules.
NOTE
While performing pin depth measurements, use different orientations
of the gauge with the connector. Average a minimum of three readings,
each taken after a quarter-turn rotation of the gauge, to reduce
measurement variations that result from the gauge or the connector
face not being exactly perpendicular to the center axis.
Gauge Accuracy
Hand held connector gauges are only capable of performing coarse
measurements. They do not provide extremely precise measurements of
pin depth. This is partially due to the repeatability uncertainties that
are associated with pin-depth measurements. At the factory, with
special gauging processes and electrical testing, the mechanical
characteristics of devices can be accurately verified.
Even then, the resultant average can be in error by as much as 0.0001
inch due to systematic (biasing) errors usually resulting from worn
gauges and gauge masters. As a result, these systematic errors are not
included in the uncertainty analysis. As the gauges endure more use,
the systematic errors could become more significant in the accuracy of
the measurement.
When to Gauge Connectors
You should gauge a connector:
• Before you use it for the first time. It is recommended that you
record the initial pin depth measurement of your device for
comparison with future readings. This serves as a good
troubleshooting tool when you suspect damage may have occurred to
the device.
• Whenever either visual inspection or electrical performance
suggests that the connector interface may be out of typical range
(due to wear or damage, for example).
• When someone else has used the calibration device, or if it has been
used on another system or piece of equipment.
