Operating Instructions
1. Battery Monitoring
Upon successful connection, the app's main screen will display real-time battery data, including:
- State of Charge (SoC): Percentage of battery charge.
- Voltage: Current battery voltage.
- Temperature: Battery temperature.
- A graphical representation of voltage over time.
The app will also indicate if the battery status is "OK" or if there are any abnormalities.
2. Cranking Test
The Cranking Test evaluates the vehicle's starting system. Follow the in-app instructions:
- Ensure the engine is off.
- Select "Cranking Test" in the app.
- Start the vehicle's engine as instructed by the app.
- The app will measure the cranking voltage and time, providing an assessment of the starter's performance.
3. Charging Test
The Charging Test assesses the alternator and charging system. This test typically involves three steps:
- Idle Speed Test: With the engine idling, turn on all electrical equipment (headlights, AC, car interior lights, etc.) and follow the app's prompts.
- High Speed Test: Keep the engine at 2500-3000 RPM and follow the app's prompts.
- Diode Ripple Test: With the engine idling, turn off all electrical equipment and follow the app's prompts.
The app will display the idle charging voltage, high-speed charging voltage, and diode ripple voltage, indicating the health of your charging system.
