ETA4550 Kelvin four-wire test leads

When the measured resistance value is less than a few ohms, the resistance of the test lead and the contact resistance between the probe and the test point are no longer negligible compared with the measured resistance. If the two-wire test method is still used, the test error will inevitably increase. At this time, the Kelvin connection method (or four-wire test method) can be used for testing. ETA4552 uses the Kelvin method for four-wire detection. The Kelvin clip has half of the jaws insulated from each other. The connection of the alligator clip provides a larger opening, and the thickened wire also meets the passage of large currents. The 4mm standard banana plug can be used in instruments with 4-wire resistance measurement functions such as micro-ohmmeters, desktop multimeters, battery internal resistance testers, etc., and can be easily used in various fields such as production lines and acceptance inspections.Features:4-wire independent connection alligator clips to eliminate lead errorsThe alligator clip provides a larger opening, and even large screws can be easily clamped. The standard plug has strong compatibility, and the 4mm full-sheath safety banana plug is exquisitely made, and the mold pressing is used to process the details for excellence.
