You use it to test voltage and ground, but also to directly activate components via the probe tip. That makes it especially useful for checking, for example, lighting circuits, relays, motors, solenoids and other electrical loads. For diagnostic work in the workshop, this saves you time compared with constantly switching between different measuring instruments. ### Measure and activate with one tool This Power Probe combines the functions of a classic voltage tester with extra diagnostic capabilities on a color display. You can read multiple measurement values on the screen and switch between different test modes depending on the circuit you are investigating. Important functions of this model include: - applying voltage and ground to the tip - DC voltage measurement - AC voltage measurement - resistance measurement - frequency measurement - pulse width measurement - test function for fuel injectors - test function for module drivers ### Practical in the garage The Power Probe 4 is equipped with a backlit color LCD, so measurement values remain clearly visible during diagnostic work. The tester works with a long cable of approximately 23 feet, which comes down to around 7 meters. That gives you plenty of freedom of movement around the car without constantly having to change connections. The tip is designed for safe diagnostic work on sensitive circuits and is described by the manufacturer as computer-safe with a 0.1 mA floating tip. This makes the device suitable for modern automotive diagnostic work where speed and control are important. ### Suitable for professional automotive applications This model is well suited to garage professionals, diagnostic specialists and advanced mechanics who regularly trace electrical faults. Especially for maintenance, troubleshooting and checking component actuation, such an extensive circuit tester is a practical tool. Within the category of specialist automotive tools, this is a strong choice if you want more than just reading voltage. You get a tester that not only checks circuits, but can also actively power and evaluate them. ## Videos - [Video 1](https://www.youtube.com/embed/WFerUXb0_Vg) ## Breadcrumbs - [Tools](https://www.auto-service.be/en/tools) -
