About This

• 【All-In-One Automotive Circuit Tester 】Attention, professional automotive technicians and DIY enthusiasts! We would like to introduce the JDIAG PB20 Circuit Tester, an advanced diagnostic tool designed to simplify the complexities of your vehicle's electrical system. It supports DC Voltage Test, Diode Test, Resistance Test, Polarity Test, Frequency Test, Continuity Test, Poor Ground Test, Activate Components, Jumper Function, Locate Short Circuit, Fuse Test, Trailer Light Test, Connection Test. So, what are you waiting for? Grab it and start your electrical adventure today!
• 【0-80 V Voltage Test Range】This electrical circuit tester with multimeter function can measure DC voltage (0-80V), resistance (0.1-200K ohms), current (up to 8A), frequency (10Hz-20Khz) , diode, continuity and can detect battery polarity. It is widely used for checking various automotive circuits, such as automotive headlights, turn signal circuits, taillights, faulty sockets, fuse connections, etc., and also for testing other 0-80V DC wires and circuits.
• 【Component Activation & Test】The power circuit probe tester has the superpower to activate all kinds of components and electrical systems. How does it work? It fires up the signal that the component needs, so you can quickly check if the component is working perfectly or needs a bit of care. You can use the activation function to test things like the starter, fuel pump, solenoid valve, blower, radiator fans, headlights, and more.
• 【Oscilloscope Mode】This advanced oscilloscope function provides clear real-time waveform visualization for testing various voltage signals. It measures four key parameters: maximum/minimum voltage values, frequency, and duty cycle, making it ideal for detecting sensors, actuators, circuit connectivity issues, and bad grounds. During oscilloscope testing, if a short circuit occurs in the vehicle, the frequency may not display properly. In such cases, please use the black ground clamp provided. When testing external devices, ensure the product is properly grounded; otherwise, the frequency may not appear on the screen.
• 【More Advanced Features】First, we’ve included a high-sensitivity stainless steel probe (detachable) that resists rust, perfect for all your testing needs. Next, the LED flashlight makes working in dark environments effortless. The copper-plated crocodile clips are designed to ensure a stable and reliable circuit connection, making it easy for you to use. When it comes to safety, we’ve got you covered with overload and overcurrent protection, ensuring no harm comes to your vehicle. Lastly, this automotive circuit tester features a 5M extended detection line that covers from front to rear of the vehicle, facilitating easy testing of the entire circuit system
