How to use

Ensure the vehicle ignition is off and inspect the tester clamps before use. Attach the red clamp to the battery positive terminal and the black clamp to the negative terminal. Power on the KW650 and select the appropriate system voltage if required. Read the displayed battery voltage and follow on-screen indications for state of charge and starting capability. To test the alternator or charging system, run the engine at idle or a slightly elevated RPM and use the alternator/charging check mode while observing the displayed results. After testing, disconnect the clamps and store the tester in a dry place.

Usage recommendations

Use the KONNWEI KW650 in well-ventilated areas and follow standard safety precautions when working with vehicle batteries: wear eye protection, avoid sparks near the battery, and ensure correct clamp polarity. For unclear or critical faults, confirm findings with a workshop-grade diagnostic tool or professional service.
