Preventing accidental shorts to adjacent components during electrical diagnostics, this digital circuit tester measures DC voltage from 3 to 30 V. It includes an insulated probe tip and a 47" (119.4 cm) cord for extended reach across engine bays or under dashboards. A large alligator clamp provides a secure ground connection to maintain accuracy while testing live circuits.
