3. Product Overview
Familiarize yourself with the main components and controls of the ANCEL S110 PRO:

- Oil Refill Port: For adding smoke oil.
- Velcro Strap: For securing the device.
- Oil Level Gauge: Indicates the current smoke oil level.
- Power Socket: Connection point for the power cord.
- Smoke Outlet Port: Where smoke exits the device.
- Flow Dial: Adjusts the smoke output.
- Flow Meter: Measures the smoke flow rate.
4. Setup and Operation
Follow these steps to set up and operate your ANCEL S110 PRO for leakage testing:
- Fill Smoke Oil: Open the oil refill port and use the provided funnel to add approximately 20ml of smoke oil (baby oil or mineral oil based) into the unit. Ensure the oil level does not exceed the MAX mark on the oil level gauge.
- Connect Pipe: Disconnect the vehicle's pipe that needs testing and connect it to the detector's smoke outlet port.
- Connect Power: Connect the power cord clamp to a DC 12V battery (red clamp to positive, black clamp to negative).
- Power On: Turn on the power switch on the device.
- Air Mode Test (Optional): Turn on the air button to check for leaks using air pressure. Observe the floatation of the ball in the flow meter; a stable ball indicates no significant leak, while movement suggests a leak.
- Smoke Mode Test: Turn on the smoke button. The pipe will be filled with smoke. Visually inspect the system for any escaping smoke to pinpoint leak points.
- Adjust Smoke Output: Use the flow dial to adjust the amount of smoke output as needed for optimal visibility.

5. Operating Modes
The ANCEL S110 PRO offers two distinct operating modes for versatile leak detection:
- Air Mode: Used for a quick initial check to determine if a leak exists. This mode is particularly useful for detecting leaks in smoke-sensitive components. After the test begins, observe the floatation of the ball in the flow meter to judge if there is a leak.
- Smoke Mode: Once a leak is suspected, switch to smoke mode to generate visible smoke, allowing you to precisely locate the leakage point within the system. Observe whether there is smoke after the test starts to judge the leakage.

6. Applications
The ANCEL S110 PRO is suitable for detecting leaks in various automotive systems, including but not limited to:
- Cooling System
- Fuel Tank System
