Best Power Supply Tester

Fluke BT510 Battery Analyzer

  • [ Polarity Testing & Continuity Testing ]: The power circuit probe tester can be used to test uncertain contact polarity in vehicles. When the it touches the positive pole, the indicator light will turn on red, and when it touches the negative pole, it will turn on green. In addition to polarity testing, the power short circuit finder can also perform continuity testing, it is mainly to test whether the circuit has continuity and whether it is short-circuited..
  • [ Quickly Tracking and Locating ]: The circuit tester is mainly used to test the on-off condition of the automobile electrical system under the 6-24V DC voltage. In most cases, a short circuit or momentary overload of a component will cause a fuse or circuit breaker to blow. When the fuse is blown due to a short circuit, using this circuit tester can help you quickly and accurately find the faulty wire and its fault point..
  • [ LED Indicator& Buzzer Dual Warning ]: In order to let you understand more intuitively and clearly understand the grounding of the components, the power circuit probe tester comes with an LED indicator and a buzzer. The test light can perform a quick self-test to ensure your tool is in good condition. When the current exceeds 7A, the circuit tester will disconnect the curren....
