The interface includes options for viewing historical data, setting maximum RPM alerts, and managing maintenance types, highlighting the app's comprehensive monitoring capabilities.
4.2 Hour Meter Functionality
The hour meter accurately tracks the operational duration of your engine, displaying both total accumulated hours and service-specific hours.
- Total Hours (TOT): Records the cumulative engine operating time, with a range of 0 to 99,999 hours and an accuracy of 0.1 hours.
- Service Hours (SVC): Enables the configuration of up to 35 distinct maintenance reminders. The SVC range is from 0 to 2000 hours, and these reminders are fully customizable via the "Moresee" app.
- Initial Hours Setting: Provides the option to set an initial hour value, useful when installing the meter on an engine that has already accumulated operating time.
4.3 Tachometer Functionality
The tachometer component provides precise engine RPM monitoring.
- Real-time RPM: Displays the current engine revolutions per minute, with a measurement range of 0 to 25,000 RPM.
- Maximum RPM: Automatically records and shows the highest RPM reached during the current engine operation cycle.
- RPM Accuracy Adjustment: The "Moresee" app allows users to select various engine firing patterns to optimize RPM measurement accuracy for different engine types.
- RPM Exceed Alert: Configurable through the app, this feature triggers a visual alert (red backlight) if the engine RPM surpasses a user-defined limit, helping to prevent over-revving.
4.4 Backlight Display
The meter incorporates a dual-color backlight system for clear visibility and alert indication:
- Green Backlight: Serves as the default display illumination, ensuring readability under normal operating conditions.
- Red Backlight: Activates automatically to signal an RPM exceed condition, providing an immediate visual warning to the operator.

5. Maintenance
5.1 Customizing Maintenance Reminders
The "Moresee" app is central to managing your equipment's maintenance schedule, allowing for personalized reminders to ensure optimal performance and longevity.
- Launch the "Moresee" app and establish a Bluetooth connection with your RL-HM058-BT device.
- Navigate to the Service (SVC) section within the application.
- Select the "Add SVC" option to configure a new maintenance reminder.
- Define the maintenance type (e.g., oil change, air filter cleaning), set the desired time interval or frequency, and add any relevant notes or remarks.
- The app supports a variety of predefined maintenance types, such as S01 for the first oil change, S03 for cleaning the engine air filter, S04 for replacing the engine air filter, and S05 for replacing the engine oil filter.
