Visual Inspection
Connectors contaminated with material such as metal debris and dust particles will increase the risk of
damaging the connector. A dusty connector affects the measurement accuracy due to lack of repeatability.
Careful visual inspection with a magnification aid and lighting should be performed at least once per day
before connecting. A “good” connector may get damaged if it is mated with a “bad” one.
Any connector with the following defects should be repaired or discarded:
•
Plating concerns that include bubbles, blisters, and deep scratches showing bare metal on the mating
plane.
•
Center conductors with bent, broken or damaged contacts.
Magnification
Use a device with a magnification range of 2X to 10X depending on the connector type.
Outer Conductor and Thread Inspection
When connector threads are clean and free from defects, coupling nuts should move freely. Inspect for defects
such as:
•
Dirt, dust, metal particles and oil
•
Damaged threads (distorted, dented, or crushed)
•
Dents or raised edges on the mating plane

Note
Connectors may lose some gloss over time due to normal usage. Light scratches, marks, and other
cosmetic imperfections found on the mating plane surfaces are signs of normal wear and should not
be considered cause for replacement.
Regular cleaning and proper connection techniques will minimize wear on the plating due to
abrasion from debris.
