4. Operating Instructions
4.1. ANCEL BT410 Battery Tester Operations
The BT410 offers comprehensive battery and charging system analysis.

Image: The ANCEL BT410 screen showing a 'GOOD BATTERY' status with detailed metrics like Health, Charge, Internal Resistance, and Rated CCA. It also illustrates recommended actions based on battery condition (Charge & Retest, Replace, Bad Cell).
- Battery Test: Select 'Battery Test' from the main menu. Follow on-screen prompts to input battery type (e.g., Regular Flooded, AGM, GEL, EFB, Lithium-Ion) and Cold Cranking Amps (CCA). The tester will display battery health, charge, internal resistance, and a recommendation (e.g., Good, Good-Recharge, Replace).
- Cranking Test: Select 'Cranking Test'. The device will prompt you to start the engine. It measures the cranking voltage and time to assess the starter motor's performance.
- Charging Test: Select 'Charging Test'. This test evaluates the alternator's performance under unloaded, loaded, and ripple conditions to ensure stable charging.
- Voltmeter: Provides real-time voltage readings of the battery.
4.2. ANCEL AD410 PRO OBD2 Scanner Operations
The AD410 PRO provides extensive OBD2 diagnostic functions.

Image: The ANCEL AD410 PRO screen illustrating a range of OBD2 diagnostic functions, including Read Codes, Clear Codes, Live Data Stream, I/M Readiness, and O2 Monitor Test, all contributing to turning off the check engine light.
- Read Codes: Retrieves Diagnostic Trouble Codes (DTCs) from the vehicle's Engine Control Unit (ECU).
- Erase Codes: Clears DTCs from the ECU and turns off the Check Engine Light (MIL). Ensure the underlying issue is resolved before clearing codes.
- I/M Readiness: Checks the status of emission-related monitoring systems to determine if the vehicle is ready for an emissions test.
- Data Stream: Displays real-time data parameters from the vehicle's sensors, such as engine RPM, vehicle speed, coolant temperature, and O2 sensor readings.
- Freeze Frame: Captures a snapshot of sensor data at the moment a DTC was set, providing valuable information for diagnosis.
- O2 Sensor Test: Retrieves O2 sensor monitoring test results for the most recently completed tests.
- EVAP Leak Test: Initiates a test of the Evaporative Emission Control System (EVAP) for leaks.
- Vehicle Information: Retrieves vehicle information such as VIN (Vehicle Identification Number), CIN (Calibration Identification Number), and CVN (Calibration Verification Number).
- DTC Lookup: Provides definitions for generic and manufacturer-specific DTCs directly on the device.
5. Maintenance
- Keep the devices clean and free from dirt, grease, and moisture. Use a soft, dry cloth for cleaning.
- Store the devices in a dry, cool environment away from direct sunlight and extreme temperatures.
- Regularly inspect cables and connectors for any signs of damage. Replace if necessary.
- No user-serviceable parts inside. Refer to qualified personnel for repairs.
6. Troubleshooting
6.1. Device Does Not Power On
- Ensure proper connection to the vehicle's OBD2 port or battery terminals.
- For AD410 PRO, confirm the vehicle ignition is in the 'ON' position.
- Check the vehicle's battery for sufficient charge.
6.2. Link Error/Communication Failure
- Verify the OBD2 connector is securely plugged into the DLC.
- Ensure the vehicle ignition is 'ON' and the engine is off.
- Check for any blown fuses in the vehicle's fuse box related to the OBD2 port.
- Confirm the vehicle is OBD2 compliant (most vehicles 1996 and newer in the US).
6.3. Screen Display Issues
