Setup and Installation
Follow these steps for proper installation of your YOOREAL Digital Hour Meter:
- Prepare Panel Cut-out: Create a rectangular opening in your panel with dimensions of approximately 1.48 x 0.96 inches (37.5 x 24.5 mm).
- Insert Meter: Gently push the hour meter into the prepared cut-out. The snap-in design will secure it in place.
- Wiring: Connect the hour meter to your equipment's power supply. The positive and negative poles of the meter are non-distinctive, allowing for easy and smooth connection. Ensure the voltage is within the AC/DC 5V to 277V range.
- Initial Hours Setup (Optional): If replacing an old hour meter, you can program the initial hours. This feature allows you to set the meter to match the previous equipment's run time. This can typically be done within the first hour of operation or through a specific button sequence (refer to the included user manual for exact steps).

Operating Instructions
The hour meter automatically tracks the total operating hours of the connected equipment when power is supplied. It also features two resettable partial timers.
- Total Hours (TOT): The main display shows the total accumulated operating hours, up to 99,999.9 hours. This value is non-resettable to ensure accurate lifetime tracking.
- Partial Timers (TMR1/TMR2): The meter includes two independent resettable timers. These can be used to track specific intervals, such as hours between oil changes or other routine maintenance tasks.
Resetting Partial Timers:
To reset TMR1 or TMR2, locate the small button on the front of the meter (usually labeled "HOURS" or similar). Press and hold this button for approximately 3-5 seconds while the desired partial timer (TMR1 or TMR2) is displayed. The timer will reset to 0.0.

Maintenance
The YOOREAL Digital Hour Meter is designed for durability and low maintenance. Its IP68 waterproof rating and epoxy resin sealing protect internal components.
- Cleaning: Wipe the display and casing with a soft, damp cloth. Avoid using harsh chemicals or abrasive cleaners.
