About this item

• 【0-80 V WIDE TESTING RANGE】JDIAG digital circuit tester with voltage display provides precise 0-80V DC voltage testing, engineered for diagnosing automotive power circuits in all 8V to 32V vehicles including cars, trucks, SUVs, boats, trailers, and motorcycles. It enables rapid testing of switches, relays, diodes, fuses, circuit continuity, and other critical components, thereby helping to reduce diagnostic time in automotive electrical systems.
• 【MULTI-FUNCTION AUTOMOTIVE CIRCUIT TESTER】JDIAG PB10 probe circuit tester helps users understand vehicle problems faster and more accurately. Supported functions such as: ✅Voltage Test✅(+-)Polarity Test✅Diode Detection✅ Component Activation✅ Continuity Test✅Grounding Test✅Test Trailer Lights & Connectors✅Trace & Locate Short Circuits✅Jumper Function✅Quick Self-test✅Reverse Connection✅ Overload Protection etc.
• 【COMPONENT ACTIVATION】: Before you perform the component activation function, you need to do the quick self-test to make sure that the electrical circuit tester is in good condition, then you can use PB10 circuit tester to activate most of components of your car, such as starter, solenoid, fuel pump, cooling fan and headlights, etc.
• 【GROUNDING TEST & JUMPER FUNCTION】: This circuit testers supports grounding test and Jumper function, allows you to test if there is a bad ground or failure in the power supply of your vehicle. This probe circuit tester is equipped with a 16.41FT extended detection line, covering the front to the rear of the vehicle, making it easy to test the entire vehicle circuit system. In addition, PB10 electric test light is bulit-in the LED lights on its top to illuminate the work environment, allows you to work better in the dark.
• 【TRACE AND LOCATE SHORT CIRCUITS】: JDIAG circuit tester automotive is equipped with advanced high sensitivity probes to help you accurately and quickly troubleshoot faulty components. Using this probe tester can save a lot of time to troubleshoot the car wiring circuit, to quickly and accurately find the faulty wire and its fault point.
• 【SCREEN UPGRADE & VOLTAGE TEST】: PB10 has upgraded the screen size to meet the needs of customers. It adopts high-definition LED digital display, which can clearly display the test results even under direct sunlight. This voltage tester easily tests voltages in the range of 0 V to 80 V and displays the values on the screen (spark plugs can be tested).
• 【OVERLOAD PROTECTION】The car circuit tester also has an overload protection device, When the current exceeds 8A, the circuit breaker inside the device will automatically trip and give out a buzzer prompt.
