6. Setup
The FOXSUR FBT-200 is designed for straightforward connection and use. It does not require an external power source as it draws power directly from the battery being tested.
6.1. Connecting the Tester
- Ensure the battery terminals are clean and free of corrosion for a good connection.
- Connect the red positive (+) clamp of the FBT-200 to the positive terminal of the battery.
- Connect the black negative (-) clamp of the FBT-200 to the negative terminal of the battery.
- Once connected, the tester will power on automatically and display the main menu.
Note: The FBT-200 features reverse connection protection, but always ensure correct polarity for optimal performance and safety.

7. Operating Instructions
The FBT-200 provides quick and accurate battery analysis. Follow these steps to perform a test:
- Connect the Tester: As described in the Setup section, connect the red clamp to the positive terminal and the black clamp to the negative terminal of the battery.
- Select Test Program: Use the Up/Down arrow buttons to navigate through the menu options. Select the appropriate test program based on the battery type (e.g., VRLA, GEL, AGM, EFB, STD, Flooded) and the specified standard (e.g., SAE, DIN, IEC, EN, CA, JIS) and CCA value. This information is typically found on the battery label. Press the ENTER button to confirm your selection.
- View Results: The tester will begin the analysis. Test results, including SOH, SOC, CCA Value, IR, and Voltage, will be displayed on the LCD screen within approximately 3 seconds.
7.1. Interpreting Test Results
The FBT-200 provides detailed metrics to help you understand your battery's condition:
- SOH (State of Health): Indicates the overall health and remaining lifespan of the battery.
- SOC (State of Charge): Shows the current charge level of the battery as a percentage.
- CCA Value: Measures the battery's ability to start an engine in cold temperatures.
- IR (Internal Resistance): A higher internal resistance can indicate a weaker battery.
- Voltage: The current voltage of the battery.

7.2. Cranking and Charging System Scan
The FBT-200 can also perform tests on the cranking and charging systems of your vehicle, providing a comprehensive diagnosis of your vehicle's electrical system.

9. Troubleshooting (FAQ)
- Q: Does this battery tester have its own power source?
- A: No, the FBT-200 is powered directly by the battery being tested.
- Q: Can the FBT-200 charge the battery?
- A: No, the FBT-200 is a diagnostic tool and does not have charging capabilities. It can only detect and analyze battery conditions.
- Q: Can the FBT-200 determine the battery's lifespan?
- A: Yes, it provides the 'State of Health' (SOH) and 'State of Charge' (SOC) percentages, which are key indicators of a battery's overall condition and remaining life.
- Q: What types of batteries can the FBT-200 be used on?
- A: It can be used on 12V and 24V lead-acid batteries, including VRLA, GEL, AGM, EFB, STD, and Flooded types.
- Q: Why are the test results inaccurate?
- A: Inaccurate results often occur if the parameters (battery type, standard, CCA value) are incorrectly entered. Please ensure you input the correct data from your battery's label before starting the test.
- Q: Why is nothing displayed on the screen?
- A: Ensure that the battery voltage is higher than 8V. Also, verify that the positive and negative clamps are connected correctly and securely to the battery terminals.

10. User Tips
- Always ensure the correct battery type and CCA values are entered into the tester for accurate readings. Incorrect input can lead to misleading results.
- For consistent readings, perform tests when the battery is at a stable temperature, ideally after the vehicle has been off for a few hours.
- Keep the battery terminals clean to ensure a good electrical connection for the tester's clamps.
