Key features

• •[WHAT-VERSATILE SUPER PROBE] The KZYEE KM05 circuit tester can solve all circuit tests: Quick Self-test/Auto Circuit Breaker/Volatge & Polarity Test/Continuity Test/Signal Circuit Test/Activate Components/Trailer Lights and Connections Test/Follow and Locate Short Circuit/Bad Ground Contacts Test. KM05 power circuit probe kit can turn complex circuit issues into simple solutions.
• •[4 IN 1 WORKING MODES] The automotive circuit tester's 4 modes to diagnose the electrical systems, which can be accessed by depressing the Mode Button and cycling through each one. DC voltage(0-60V): read the DC voltage with a resolution of 0.1 volts. AC voltage(0-60V/0-10KHz): read the Max.voltage, the Min.voltage, and frequency. Resistance(0-100KΩ): read the resistance between the tip and auxiliary ground lead. Diode(0-3V): identify the positive and negative poles of the diode. Effortlessly switch between 4 operating modes for ultimate versatility and ease of use.
• •[ACTIVATING COMPONENTS & MULTIFUNCTION TEST] KM05 circuit tester automotive tool can activate component in your hand/ in the vehicle/ with ground. By generating activation signals to electrical components, you can accurately judged whether the component is intact, such as blower motor, power window motor, relay, windshield wiper, rear window defroster, lights, radiator fans, fuel injectors, etc. The continuity test function is used to detect whether the wires in the car circuit are open-circuited.
• •[TRAILER LIGHTS TEST] While the circuit probe tester in DC Voltage mode, clip the auxiliary ground lead to the trailer ground, probe the contacts at the jack and then apply voltage to the probe tip. This trailer light tester helps you check the function and orientation of the connector and trailer lights.
• •[OVERLOAD PROTECTION] The circuit breaker is a valuable test tool as well as a safety measure to protect the tool from overload. The electrical circuit tester is short-circuit protected. Its internal circuit breaker will trip if it becomes overload. Please NOTE: If the circuit breaker tripped, the circuit system diagnostic tool shuts down and resets itself.
• •[TRACKING & LOCATING SHORT CIRCUITS] In most cases, short circuit or instant overload of component will lead to blown fuse or circuit breaker tripping.Using this automotive short circuit finder can save a lot of time to troubleshoot the car wiring circuit, to quickly and accurately find the faulty wire and its fault point.
