A low power magnifier, less than 6x, is adequate to inspect
the parts. Do not be concerned with minor defects such as
scratches visible only with the magnifier; these will
probably not affect performance. If inspection shows
moisture, oil, or other residue, clean the parts.
When examining the female connector, look at the inner
contact to see that the gripping fingers are not bent.
The greatest variable in the accuracy and repeatability for
these demanding measurements is the experience and
attention to detail of the person actually making the
connections. Before going on, examine all parts carefully.

Cleaning
The parts must be clean in order to achieve best results.
Use isopropyl alcohol, dry air or nitrogen, and lint-free
swabs to remove contaminants.
In general, do not force cleaning materials into connector
parts and do not immerse the part in cleaning fluids. Just
moisten the swab and wipe the surface lightly. To dry the
part, use a dry swab or light pressure from a dry air or
nitrogen source.
Do not leave lint or particles of the swab in the connector.
If there is doubt about the condition of the connector, use
the connector gages to check the connector dimensions.
The same care should be used for all connectors, especially
the device under test.
