5. Bedienungsanleitung
- Sichere Schutzhülle: After inserting the spark plugs, ensure the transparent protective cover is securely closed over the spark plugs. This is crucial for safety.
- Frequenz anpassen: Turn the Rotary Switch clockwise to increase the working frequency. The frequency can be adjusted from 0 to 6000rpm. A higher frequency simulates higher engine speeds, resulting in a stronger spark intensity.
- Beobachten Sie Spark: Observe the spark plugs through the protective cover. A strong, consistent blue spark indicates a healthy spark plug. Irregular, weak, or absent sparks suggest a faulty spark plug.
- Compare Spark Plugs: When testing two spark plugs simultaneously, compare the spark intensity and consistency between them to identify any performance differences. This helps in diagnosing which spark plug might be failing.
- Complete Testing: After testing, turn the Rotary Switch to the "OFF" position. Disconnect the power adapter and carefully remove the spark plugs from the sockets.
