Comprehensive measurement capabilities: AC/DC voltage, DC current, and resistance, plus circuit continuity test, battery check, diode/transistor PN junction testing, and hFE test. It functions as a voltmeter, ammeter, ohmmeter, car battery tester, amp meter, and voltage tester. Ideal for checking household outlets, fuses, batteries (including vehicle), and automotive circuitry. Safety and durability: Overload protection on all ranges to support long-term use. Low battery indication and audible continuity checks to confirm circuit or wire conductivity. Double insulation with an angled stand for hands-free operation. Easy to use: 2.7 inch large backlit LCD display with data hold. The high-contrast back-light improves visibility in dim areas. Widely useful for car repair, home use, schools, laboratories, families, and factories. Recommended by many teachers, professionals, and engineers. Protective shell and stand: Nice orange protective shell with an integrated stand. Can be handheld or stood on the fold-out stand. Removable thick rubber cover provides drop protection and extra bump resistance; non-slip, slightly soft plastic. Use scenarios: - Test household outlets, fuses, and batteries including vehicle batteries. - Inspect automotive circuitry and wiring for continuity and faults. - Troubleshoot electronics by testing diodes, transistor PN junctions, and hFE in circuits.
