Use, Maintenance, and Care of the Devices
Visual Inspection
Inspect the Mating Plane Surfaces
Flat contact between the connectors at all points on their mating plane surfaces is required for
a good connection. See Figure 2-1 on page 2-3 . Look especially for deep scratches or dents,
and for dirt and metal particles on the connector mating plane surfaces. Also look for signs of
damage due to excessive or uneven wear or misalignment.
Light burnishing of the mating plane surfaces is normal, and is evident as light scratches or
shallow circular marks distributed more or less uniformly over the mating plane surface. Other
small defects and cosmetic imperfections are also normal. None of these affect electrical or
mechanical performance. If a connector shows deep scratches or dents, particles clinging to
the mating plane surfaces, or uneven wear, clean and inspect it again.
Inspect Female Connectors
The 1.85 mm slotted female connector is designed and fabricated to meet and exceed the
performance requirements of an instrument-grade connector. In order to maintain this
performance level, the female contacts of each device should be inspected prior to use. Refer
to Figure 3-2 on page 3-4 . Make sure that the contacts are formed symmetrically. The outside
edge of the contacts must be very sharp. Also, the center conductor must be free of nicks,
scratches, and dings.
NOTE
Inspection of connectors is particularly important when mating nonprecision to
precision devices.
