Key benefits - Quick and clear voltage readings with a digital display. - Indicates polarity (positive and negative) to simplify correct test setup. - Simple operation: probe on the negative pole and clamp on the positive pole triggers a visible LED confirmation. - Broad vehicle compatibility with a wide voltage range for reliable checks. Core features - Automotive voltage tester with digital display for easy voltage reading. - Displays both polarities, helping identify correct connection and polarity quickly. - LED indicator activates when the probe contacts the negative pole and the clamp contacts the positive pole, providing a visual confirmation. - 26-32V voltage range for compatibility with most cars and automotive circuits. - Suitable as an automotive electrical system tester and a car digital circuit tester. How it works - Connect the probe to the negative pole and secure the clamp to the positive pole; the LED indicator lights to confirm the circuit is live, and the digital display shows the voltage level. Specifications and compatibility - Voltage range: 26-32V - Broad vehicle compatibility due to the 26-32V range - Functions as an automotive voltage tester, automotive electrical system tester, electric circuit tester, and car digital circuit tester Use scenarios - Battery and charging system check: verify voltage at a circuit point by placing the probe on the negative pole and the clamp on the positive pole to confirm presence of voltage. - Circuit diagnostic during installation: quickly confirm power presence at fuses or components by observing the LED indicator and voltage reading. - Fault isolation in automotive electrical systems: test various circuits and circuits to determine if voltage is present, aiding troubleshooting without removing components. Note - This device is designed to be used for automotive voltage testing and circuit checks within its 26-32V range, providing a straightforward, reliable test method with a digital readout and polarity indication.
