1. Can test whether the circuit is in a continuous state or an open circuit state. (The green light is on to indicate that the circuit is in a continuous state, and the green light is off to indicate that the circuit is in an open circuit state.) 2. Can quickly test the working state of the circuit diode component and determine the open circuit and continuity. 3. Grounding test: For whether there is a large current flowing through the component, the good grounding of the negative pole of the component can be tested. (The green light is on and a buzzer sounds, indicating good grounding, and the green light is on without a buzzer, indicating poor grounding.) 4. Current overload protection: When the current is overloaded or underloaded, the machine will automatically disconnect the circuit for protection and sound a buzzer alarm to reduce unnecessary losses. 5. DC voltage test range: 6-24V 6. Current: 10A 7. Size: 220x30x30mm 8. Power cord length: 4 meters
