RL-069 RELIFE Rosin Short Circuit Detector Designed For Repairing Electronics Like Mobile Phones and Computer Motherboards. Key Features Fast Atomization: Rapidly heats to produce dense smoke, allowing for immediate fault detection. Precise Detection: Increases the precise contact area of the rosin atomization to clearly show where a component is overheating due to a short. Cordless Design: Features a built-in rechargeable lithium battery and supports USB charging. Enhanced Durability: Equipped with a thickened glass cover that is resistant to breaking and helps concentrate the smoke. Package Contents The typical kit includes several essential components for operation: Rosin Atomizing Pen: The main device used for heating the rosin. USB Charger: For recharging the internal battery. Cleaning Brush: Used to maintain the device and clear away residue. Glass Cover: Protects the heating element and contains the smoke. Operating Instructions To use the RL-069, you typically follow these steps based on standard operation for this type of device: Power On: Press the main button five times rapidly to turn the device on. Add Rosin: Place a small piece of rosin on the heating element under the glass cover. Atomize: Long-press the power button to heat the rosin and generate smoke. Detect: Apply the smoke to the suspected area of the PCB; the rosin will melt specifically at the point where the short circuit is generating excess heat.
