What are Test Leads components?

Test leads are the critical interface between your DUT and measurement hardware. Selection hinges on voltage/current ratings, cable flexibility, and connector compatibility (e.g., shrouded banana, BNC). Always prioritize CAT safety ratings over mere physical fit.

How to Choose Test Leads Components

Selecting the right lead ensures signal integrity and operator safety.

  1. Safety Rating (CAT)

    Match the CAT rating (I-IV) to your environment to prevent arc flash and electrical shock.

  2. Connector Interface

    Verify compatibility with your instrument ports, such as shrouded banana plugs or BNC connectors.

  3. Cable Flexibility

    Silicone-jacketed leads offer superior flexibility and heat resistance compared to PVC for bench work.

  4. Current Capacity

    Ensure wire gauge (AWG) is sufficient for your maximum expected current to avoid voltage drops.

  5. Probe Tip Geometry

    Select tip shapes (needle, hook, alligator) based on the accessibility of your test points.
