Operation
The YOOREAL Digital Inductive Hour Meter operates automatically once installed correctly. It detects engine activity through the inductive cable wrapped around the spark plug wire.
- Engine Start Detection: When the engine starts working, an hourglass icon on the meter's display will flash, indicating that it is actively tracking time.
- Hour Accumulation: After approximately 6 minutes of continuous engine operation, the display will update to 0.1 hours. The meter continues to accumulate hours in 0.1-hour increments.
- Total Hours Display: The meter displays the total accumulated hours up to 99,999 hours.
- Data Retention: All recorded hours are automatically saved and retained even when the engine is turned off or the meter is not actively running.
No manual input or reset is required for basic hour tracking. The meter is designed for continuous, maintenance-free operation regarding its time-tracking function.
Maintenance
The YOOREAL Digital Inductive Hour Meter HM006A is designed for minimal maintenance due to its sealed construction.
- Battery Life: The meter is powered by a CR2430 300mAh battery, which is non-replaceable. The battery is designed to last for the lifespan of the product.
- Cleaning: If the meter becomes dirty, wipe it with a soft, damp cloth. Avoid using harsh chemicals or abrasive cleaners.
- Inspection: Periodically check the inductive cable and mounting for any signs of wear or damage. Ensure the cable remains securely wrapped around the spark plug wire and the meter is firmly mounted.
The primary purpose of the hour meter is to help you track the service intervals of your engine. Refer to your engine's manual for recommended maintenance schedules based on operating hours.
Troubleshooting
If your YOOREAL Digital Inductive Hour Meter HM006A is not functioning as expected, consider the following:
- Display Not Activating: Ensure the inductive cable is securely connected to the meter and properly wrapped around the spark plug wire (at least 5 laps). The meter relies on the spark plug's ignition signal.
- No Hour Accumulation: Verify that the engine is running for a sufficient duration (at least 6 minutes) for the meter to register 0.1 hours. If the hourglass icon is not flashing, the meter is not detecting the engine's operation. Re-check the cable connection and wrapping.
- Physical Damage: Inspect the meter and cable for any visible damage. Although the meter is shockproof and waterproof, extreme impacts or prolonged exposure to harsh conditions can affect its functionality.
If troubleshooting steps do not resolve the issue, please contact YOOREAL customer service for further assistance.
