6V 12V 24V Automotive Electrical Tester Pen Voltage Tester with LCD Screen, Polarity Test, Flashlight, Car Fuse Tester

Dimensions: 50 x 36 x 124 mm

Powerful Circuit Tester: This automotive circuit tester is suitable for all 5-30V automotive electrical systems. It enables polarity identification, voltage testing, fuse detection, LAN circuit testing, ground fault detection, short circuit tracing and location, and pulse signal testing. This probe tester allows you to easily and accurately detect problematic circuits.

Digital LED Display and Test Bulb: This automotive electrical tester displays the voltage in real time for a quick and accurate reading of the current voltage. Additionally, the brightness of the bulb at the probe tip varies according to the voltage, allowing you to quickly identify power circuit faults. Polarity Tester and Frequency Prediction: This automotive fuse tester uses red and green LEDs to quickly distinguish positive from negative polarity. When the pen is connected to a 5-30V AC signal, the digital display allows you to estimate the frequency range. It can be used to measure signals from fuel injectors, spark plugs, crankshaft sensors, etc. Three operating modes: The voltage tester is equipped with a switch and a 12V 5W test bulb, allowing you to easily switch between modes. You can use the LED digital display and the bulb simultaneously, or select just one to test voltage and accurately diagnose faulty battery or fuse circuits. Easy to use and versatile: The logic probe features a wide, sturdy alligator clip for convenient one-handed operation. The sharp stainless steel probe with a rubber-protected tip is ideal for piercing wires and even hard-to-reach areas. This automotive tester can be used as a voltage, fuse, battery, or probe tester, making it ideal for a variety of cars, trailers, trucks, RVs, motorcycles, boats, etc.
