5. Setup and Preparation
5.1 Power Connection
Connect the provided Power Cord to the Power Supply Input (10) on the ANCEL JC200 and to a 12V vehicle battery. Ensure correct polarity. The device requires a 2Amp power supply.
5.2 Injector Mounting
- Select the appropriate adapters (e.g., Φ9-11.3, Φ11-12.8, Φ13-14.5) for your injectors.
- Mount the injectors onto the Base Plate (5) and secure them using the Lock Thread (8) and Lock Nut (7).
- Connect the Signal Cords to the injectors and the Pulse Signal Output (11) on the main unit.
- Ensure the Fluid Deliver Switch (9) is OFF before proceeding.
5.3 Filling the Tank
Pour the appropriate test fluid into the tank through the Fuel Refill Port (13). The tank capacity is 150ml. Observe the Fuel Level Gauge (4) to ensure adequate fluid for testing.
6. Operating Modes and Features
The ANCEL JC200 offers several key functions for comprehensive injector testing and cleaning:

6.1 Main Functions
- Uniformity Test: Checks the consistency of injections across multiple injectors.
- Atomization Observation: With the help of the bright backlight, you can observe the spray atomization pattern of the injector in a comprehensive and careful manner.
- Tightness Test: Detects the tightness and any dropping of fuel from the injector under working pressure.
- Fuel Injection Volume Detection: Measures the fuel injection volume of the injector under specific working conditions.


6.2 Key Features
- Dual Pulse Signal Output: Provides ECU control signals to two injectors simultaneously for efficient comparison testing.
- Pressurized Air System: Uses pressurized air to push test fluid, ensuring stable pressure output and consistent test conditions.
- DC12V Power Supply: Enhances the portability of the product, allowing use with a vehicle battery.
- Visual Oil Tank Liquid Level: The oil tank liquid level is displayed visually, and the test agent can be recycled.
- Bright Background Light: Allows clear observation of the fuel injector's performance during operation.
- Replaceable Composite Joints: Accommodates different injector types.
