Test Lead

Test leads, also known as test probes or test cables, are essential accessories used with electronic testing and measuring instruments such as multimeters, oscilloscopes, and power supplies. They provide a means of connecting the instrument to the device or circuit under test, allowing for accurate measurements and analysis.

Test leads typically consist of a pair of insulated wires with connectors at each end. One end of the test lead is attached to the instrument, while the other end is used to make contact with the test point or component being measured. The connectors may include banana plugs, alligator clips, spade terminals, or other types of connectors depending on the instrument and application.

The quality and construction of test leads are crucial for ensuring reliable and accurate measurements. High-quality test leads feature durable and flexible insulation, often made from materials such as silicone or PVC, to withstand frequent use and prevent electrical interference. The probe tips are typically made of metal, such as stainless steel or brass, to provide a secure and low-resistance connection.
