5. Setup
5.1 Mounting the Hour Meter
The RL-HM016B hour meter is designed for simple stick-on mounting. Choose a flat, clean, and dry surface on your equipment where the meter will be exposed to engine vibrations.
- Clean the chosen mounting surface thoroughly to ensure proper adhesion.
- Peel off the protective backing from the double-sided adhesive tape.
- Firmly press the hour meter onto the cleaned surface, ensuring good contact.

5.2 Adjusting Vibration Sensitivity
The hour meter has two vibration sensitivity settings: Low (LO) and High (HI). Adjust the sensitivity based on the vibration intensity of your equipment to ensure accurate tracking.
- LO (Low Sensitivity): Suitable for machines with strong vibrations (e.g., some generators, chainsaws).
- HI (High Sensitivity): Ideal for equipment with weaker or less consistent vibrations (e.g., electric fans, some lawn mowers).

6. Operation
6.1 Total Hours (TOT) Display
The hour meter automatically tracks the total operating time of your equipment when it senses vibrations. The display shows the total accumulated hours (TOT) up to 99,999 hours.

Figure 6.1: Total Hours (TOT) display.
6.2 Partial Timer (PAr)
The partial timer allows you to track specific operational periods, which is useful for scheduling maintenance tasks. This timer can be reset independently without affecting the total hours.

6.3 Lock Shutdown
To extend battery life when the meter is not in use or during transport, you can activate the lock shutdown feature. This turns off the LCD display while retaining all recorded data.
7. Maintenance
The Runleader Digital Wireless Hour Meter is designed for minimal maintenance. The internal lithium metal battery is included and has a long lifespan. If the battery needs replacement, consult the manufacturer's guidelines or a qualified technician.
- Keep the meter clean and free from excessive dirt or debris.
- Ensure the mounting surface remains secure.
- Avoid exposing the meter to extreme temperatures beyond its operating range.
8. Troubleshooting
If you encounter issues with your hour meter, consider the following:
- Meter not displaying hours:
- Ensure the equipment is generating sufficient vibration.
- Check the vibration sensitivity setting (try switching between LO and HI).
- Verify the meter is securely mounted and receiving vibrations.
- Inaccurate hour readings:
- Adjust the vibration sensitivity to match your equipment's vibration level.
- Ensure the meter is not picking up extraneous vibrations from other sources.
- Display is off:
- The meter might be in lock shutdown mode. Press any button to wake it up.
- The internal battery may be depleted.
