  • ...circuit, and whether the circuit is in a continuous state or an open state. The red light is on when the probe tip is in contact with the positive pole or the circuit is open, and the green light is on when the probe tip is in contact with the negative pole or the circuit is in a continuous state..
  • [Component Test & Diode Test] Contact the probe tip to the positive terminal of the tested component to active the component. It can detect whether there is a large current flowing through the element and whether the negative electrode of the detection element is well grounded. Quickly test diode assembly operation and determine if circuits are opened or continuous. When the grounding is good, the green light will be on and a "beep" will sound..
  • [Current Overload Protection & Locating Short Circuits]: When the current is overloaded, the car circuit tester machine will automatically open circuit protection and emit a "beep" sound to reduce unnecessary losses and make our products durable. If LED light green with buzzer, short circuit or overloading component appears in this side. Following the wire in the direction of the short can help you find the location of the short..
