Key benefits Secure, comfortable handling: PVC-coated surfaces give a reliable, non-slip grip for safe connection and manipulation. Safe, visible insulation: Copper conductors are fully insulated to protect users and reduce short-circuit risk during teaching or field tests. Quick, hands-free connections: U-shaped wire ends make it easy to hook onto battery terminals and hold contacts for hands-free measurement. Versatile test set: Designed for educational demonstrations, general circuit testing, and automotive diagnostics; expands the ways you can test and monitor circuits. Primary features and specifications Conductor: Insulated copper wire for low-resistance, consistent electrical contact and long-term reliability. Handles/coating: PVC surface on accessory handles for comfort and electrical isolation. Connector form: U-shaped wire ends for secure attachment to battery posts and terminal studs. Function set: Functions as isolation test leads, teaching wires for current demonstrations, and test lead cables compatible with tester monitors and common multimeters. Application scope: Test lead set intended for multiple test applications including classroom models, bench testing, remote/hands-free battery measurement, and automotive troubleshooting. Practical use scenarios Classroom and training labs: Use on educational circuit models to demonstrate current flow, battery connections, and basic measurements; insulated leads keep students safe while they practice hands-on experiments. Field or remote testing: Attach U-shaped leads to a battery for steady, hands-free voltage or load checks when space or personnel is limited. Automotive diagnostics and workshop use: Employ the test lead set for continuity checks, battery tests, and portable tester/monitor connections to expand diagnostic capabilities. What this product solves Eliminates awkward or unstable battery connections by providing U-shaped, secure contacts. Reduces handling risk and accidental shorts through insulated copper conductors and PVC-coated grips. Increases testing flexibility by combining teaching, bench, and automotive test functions in one lead set compatible with standard testers and monitors.
