All-in-one Automotive Circuit Tester
This is the latest generation electrical system tester, designed to help you troubleshoot all kinds of automotive electrical and electronic problems efficiently. With clear result display in both waveform and digital formats, LED lights and buzzer alarm for quick polarity identification, a 90° foldable screen for data viewing in narrow areas, and built-in flashlights for better illumination in dark environments, it delivers a more convenient and user-friendly testing experience. Supporting online updates and 9 languages, it is a great choice for DIYers, electricians, and professional technicians, offering higher efficiency, improved accuracy, and enhanced ease of use in daily diagnostics.
Component Activation and Injector Test
➤ Component Activation: Quickly test and verify components by sending electrical signals, such as car lights, motors, windshield wipers, radiator fans, relays, fuel injectors, & other on/off-board electric equipment.
➤ Injector Test: Identify injector issues like blockages or wear without disassembling the fuel system. 4 modes for testing:
Mode 1: 250 ms positive pulse
Mode 2: 7 ms positive, 20 ms negative pulse (1.4s cycle)
Mode 3: 4 ms positive, 10 ms negative pulse (1.4s cycle)
Mode 4: Continuous 7 ms positive, 20 ms negative pulse
Efficient Diagnostics: Test components and injectors in real-time, locate faults quickly, and verify system reliability without disassembly.
All-in-One Automotive Power Circuit Probe Tester
This cost-effective probe tester integrates Component Activation, Fuel Injector Test, Relay / Fuse / Trailer Light Test, and full AC/DC Voltage, Resistance & Diode Testing into one professional tool. It supports 0–5V ECU signal checking, polarity & continuity tests, and quickly locates short circuits, bad grounds, and faulty wiring, allowing fast, accurate diagnosis across vehicle electrical systems with maximum efficiency and convenience.
6-In-1 Multimeter & Oscilloscope Tester
The V500 circuit probe tester works more powerfully than others, combining multimeter and oscilloscope functions into one advanced diagnostic tool. The multimeter mode contains voltage (VDC), resistance (OHM), diode (DIO), current (AMP), frequency, and polarity (P-N) testing. The oscilloscope function features clear real-time waveform diagrams for testing various voltage signals, with 4 parameters: AC/DC voltage, resistance value, frequency, and duty cycle. This advanced capability makes the V500 ideal for detecting sensors and actuators, checking circuit connectivity, and identifying bad grounds, helping users diagnose electrical issues more accurately and efficiently.
One-Click Smart Test & Relay Test
Without switching between different test modes, this intelligent power circuit probe tester kit can automatically measure voltage, resistance, and positive/negative polarity at the same time while turned on, greatly simplifying the testing process. When the probe tip connects to the negative terminal, the green LED lights up with a buzzer alert. When connected to positive polarity, the red LED lights up, providing clear and instant identification. This one-click smart test design helps save time, reduce operating errors, and improve diagnostic efficiency for both professionals and DIY users.
