1. Suitable for automotive repair, electrical system maintenance, vehicle electrical fault diagnosis, battery maintenance and testing, etc.
2. A multi-functional testing device for 12V and 24V automotive electrical systems, integrating battery testing and relay testing functions. Applicable to electrical system fault diagnosis for various vehicle models, including cars, motorcycles, and trucks.
3. Users can select the corresponding socket according to the number of relay pins and insert the relay into the test area. The device panel allows switching between 4PIN and 5PIN modes. Test results are displayed via LED indicators: green indicates a normal relay, and red indicates an abnormal relay.
4. Battery testing function: connecting the battery positive and negative terminals with red and black clamps, the device automatically detects the battery status. Test results can display parameters such as voltage, internal resistance, cold start current (CCA), state of health (SOH), and state of charge (SOC).
5. Charging system testing: detects vehicle charging voltage (loaded/unloaded) and ripple voltage, helping to determine if the alternator and rectifier systems are functioning correctly.
6. Waveform display function: the device is equipped with a real-time voltage waveform display, allowing observation of voltage change trends and assisting in the analysis of the electrical system's dynamic response.
7. Dimensions: 16 x 8.9 x 2.3 cm
