4. Setup and Initial Use
The KW210 Battery Tester is designed for ease of use. It does not require internal batteries and powers on automatically when connected to a 12V vehicle battery.
4.1 Connecting the Tester
- Ensure the vehicle's ignition is off.
- Locate the vehicle's 12V battery.
- Connect the red crocodile clip to the positive (+) terminal of the battery.
- Connect the black crocodile clip to the negative (-) terminal of the battery.
- The tester will power on automatically and display the main menu.
4.2 Menu Navigation
Use the UP and DOWN arrow buttons to scroll through menu options. Press the ENTER button to select an option or confirm an action. Use the ESC button to return to the previous screen or cancel an operation.
5. Operating the KW210
The KW210 offers various testing functions to diagnose your vehicle's battery and charging system.
5.1 Battery Test
This function checks the overall health of the battery, including its capacity (CCA), internal resistance, and remaining life percentage.
- From the main menu, select "Battery Test" (or similar option).
- Follow the on-screen prompts to input battery type and CCA rating if required.
- The tester will display results such as battery voltage, charge percentage, healthy percentage, internal resistance, and a status (e.g., GOOD BATTERY, REPLACE BATTERY).
5.2 Cranking Test
The cranking test evaluates the battery's ability to start the engine.
- From the main menu, select "Cranking Test".
- Choose "In-Vehicle" or "Out-of-Vehicle" based on your setup.
- Follow the on-screen instruction to "START ENGINE".
- The tester will analyze the cranking voltage and time, then display the results and status.
5.3 Charging Test (Alternator Test)
This test checks the vehicle's charging system, including the alternator's output voltage and ripple status.
- From the main menu, select "Charging Test".
- The tester may prompt you to increase the engine RPM to 2500 r/min and hold for 5 seconds.
- Press ENTER to continue.
- The tester will display loaded voltage, unloaded voltage, and ripple voltage.
5.4 Ripple Test
The ripple test measures the AC voltage component in the DC charging system, indicating potential issues with the alternator's rectifier diodes.
- This test is typically integrated into the Charging Test.
- The tester will display the ripple voltage (e.g., in mV). High ripple voltage can indicate a faulty alternator.
5.5 Data Storage and Review
The KW210 can store test results for later review. Navigate to the "Data Storage" or "Review" option in the main menu to access previously saved test data.
5.6 Printing Test Results
You can print test results and battery reports by connecting the KW210 to a PC via the provided USB cable and using the KONNWEI update tool software.
6. Language Settings
The KW210 supports multiple languages for user convenience.
- From the main menu, navigate to "Setup".
- Select "LANGUAGE".
