Use, Maintenance, and Care of the Devices
Visual Inspection
Visual Inspection
Visual inspection and, if necessary, cleaning should be done every time a connection is made. Inspect
mating surfaces for dirt, dust, foreign particles, or scratches, which can degrade device performance. A
damaged mating surface can damage any good surface connected to it. If necessary, clean all mating
surfaces.
Magnification is helpful when inspecting mating surfaces, but it is not required and may actually be
misleading. Defects and damage that cannot be seen without magnification generally have no effect on
electrical or mechanical performance. Magnification is of great use in analyzing the nature and cause of
damage and in cleaning mating surfaces, but it is not required for inspection.
