Usage Tips:The jumper is made of PVC material, which is safe, reliable, and has strong elasticity. Test the surface coating of lead, which is glossy. It will not cause wire crossing or short circuit.Wire: 22-AWG copper wire, PVC insulation, test lead suitable for most lightweight electronic products. Very suitable for electrical testing, such as experiments, test boards, prototype design, and troubleshooting. Widely used in laboratories, shops, schools, homes, and industry. High quality productsThe test jumper adopts a detachable design. The usage method is very simple and convenient. Connecting from two terminals is very fast, for example, a power test probe, which can be frequently used for circuit electrical testing. In addition, crocodile clip appliances are widely used in motor testing, electrical testing, digital product and power connection testing.When testing the performance of electronic devices, the test leads are expandable and can be tightly and conveniently connected to the battery power supply. The PVC plastic cover is insulated, which to some extent protects safety. But please note that the clamp terminals are metal and should not be used above the rated voltage.Widely used in laboratories and electrical testing, such as experiments, circuit boards, prototype design, troubleshooting, etc. Can be used in laboratories, shops, schools, homes, and industries.
