A 24-volt circuit tester that supplies power and ground for component activation while monitoring electrical values through an integrated digital voltmeter with min/max voltage capturing. This instrument identifies short circuits and bad grounds across a 20-foot (6.1 m) lead, providing the reach necessary for bumper-to-bumper diagnostics. It also functions as a continuity tester and includes a 4 mm banana jack for connecting additional leads or probes.
