6. Setup Instructions
Follow these steps to assemble and prepare your RELIFE RL-069 Rosin Atomizer for use:
- Install the Atomizing Rod: Carefully insert the atomizing rod into the main body of the pen.
- Add Rosin: Place a small amount of solid rosin onto the tip of the atomizing rod. Ensure it is securely seated.
- Install the Glass Cover: Gently place the glass cover over the atomizing rod and heating element, twisting if necessary to secure it.
- Install the Atomizing Tube: Attach the atomizing tube (mouthpiece) to the top of the glass cover.

7. Operating Instructions
Once assembled, follow these steps to use your rosin atomizer for short circuit detection:
- Power On: Press the switch button 5 times rapidly to turn on the device. The indicator light should illuminate.
- Atomize Rosin: Press and hold the switch button to activate the heating element and atomize the rosin. Smoke will begin to emit from the atomizing tube.
- Aim at Detection Area: Direct the rosin smoke towards the suspected short circuit area on the PCB. The smoke will adhere to the surface.
- Observe Short Circuit Point: Apply power to the PCB. The rosin smoke will quickly dissipate from the exact location of the short circuit, revealing the fault point.
- Power Off: After use, press the switch button 5 times rapidly to turn off the device.

8. Maintenance
Proper maintenance ensures the longevity and optimal performance of your device:
- Cleaning: After each use, allow the device to cool down. Use the provided cleaning brush to gently remove any residual rosin from the atomizing rod, glass cover, and heating element.
- Charging: Recharge the device when the battery is low. Connect the Type-C charging cable to the charging port and a suitable USB power source.
- Storage: When not in use, store the atomizer in its original packaging or a protective case to prevent damage.
9. Troubleshooting
- Device not turning on: Ensure the battery is charged. Press the power button 5 times rapidly to activate.
- No smoke/poor atomization: Check if there is enough rosin on the atomizing rod. Ensure the atomizing rod and heating element are clean and free of blockages. The glass cover and atomizing tube should be correctly installed.
- Inaccurate detection: Ensure the PCB is clean before applying rosin smoke. Make sure the rosin is evenly distributed.
10. User Tips
- Rosin Quality: Use high-quality, pure rosin for best atomization results and clear short circuit detection.
- Even Application: Try to apply the rosin smoke as evenly as possible over the suspected area for more precise fault identification.
- Model Verification: If you encounter product variations (e.g., models with an 'A' suffix), always verify the exact model number and specifications with your supplier to ensure compatibility and correct usage.
