    Create an automated system to test continuity in circuit boards. Combine these spring-loaded test probes with Spring Test Probe Sockets that are permanently attached to testing fixtures. Select a socket that has the same minimum spacing between probe centers and is for the probe's barrel length. Test probes and sockets are sold separately.
    Probes with flat and rounded tips are nonmarring, while probes with pointier tips may leave light marks on surfaces. Sharper probes, however, will be more effective at penetrating corroded or finished surfaces.
    When installing test probes and sockets, adhere to the "minimum spacing between probe centers" to maximize testing points while preventing probes from interfering with each other. Spring test probes will produce optimal results when your system is set up to achieve the working stroke length. Initial spring force is the force required to start compressing the probe; maximum spring force is the force applied at the working stroke length.
    Round Tip—Round probes test flat surfaces.
    90° Cup Tip—90° cup probes guide protruding objects, such as terminals, pins, and long wire leads.
    Flat Tip—Flat probes have a large surface area that’s good for use with solder bumps and protruding posts.
    Waffle Tip—Waffle probes have many points of contact to test flat surfaces as well as terminals and pins.
    Crown Tip—Crown probes test wire leads, posts, and flat surfaces. The points on crown probes are angled and longer than those on waffle probes, so they’re better at cutting through corrosion.
    30° Spear Tip—Use 30° spear probes on lightly corroded flat surfaces and holes that must remain free of marks.
    Chisel Tip—Chisel probes make contact at multiple angles to cut through moderate corrosion.
    90° Razor Tip—90° razor probes have a narrow tip to pierce through heavy corrosion.

    Mount these sockets to fixtures, attach wire from your electrical testing equipment, and add Spring Test Probes to create automated systems to test continuity in circuit boards. Use a probe that has the same minimum spacing between probe centers and has the specified barrel length. Test probes and sockets are sold separately.
    When installing test probes and sockets, adhere to the "minimum spacing between probe centers" to maximize testing points while preventing probes from interfering with each other.
    Quick-Disconnect-Terminal Wire Connection—Sockets with a quick-disconnect terminal connection require an adapter (sold separately) to quickly and easily connect and disconnect your wire from the socket terminal. All of these sockets click in place for a hold that’s more secure than wraparound wire terminal connections, but less secure than solder connections. They also have sleeving for electrical insulation.
    Jack—Sockets with a jack have a lower profile and offer a more secure hold than those with a plug. Use a crimper (not included) to install wire onto the adapter. These sockets can’t be reused due to their crimped connection.
    Plug—Sockets with a plug offer the fastest wire installation time. Simply slide the plug over the wire and barbs will grip the wire sleeving—no need for crimpers. These sockets can be reused. They are not, however, as secure as those with a jack because their hold can loosen over time.
    Solder Connection—For sockets with a solder connection, place wire onto the cupped terminal on the socket and solder to create a metallic bond that is stronger than quick-disconnect and wraparound wire terminal connections. Add additional sheathing, such as heat-shrink tubing (not included), for electrical insulation.
    Wraparound Connection—For sockets with a wraparound wire terminal connection, install wire by winding it around the squared terminal on the socket. Their connection is not as secure as quick-disconnect terminal and solder connections. Add additional sheathing, such as heat-shrink tubing (not included), for electrical insulation.
