5. Operating Instructions
- Secure Protective Cover: After inserting the spark plugs, ensure the transparent protective cover is securely closed over the spark plugs. This is crucial for safety.
- Adjust Frequency: 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.
- Observe 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.

6. Maintenance
- Cleaning: Keep the device clean and free from dust and debris. Wipe the exterior with a soft, dry cloth. Do not use abrasive cleaners, solvents, or immerse the device in water.
- Storage: Store the SPT101 Spark Plug Tester in a dry, cool place away from direct sunlight and extreme temperatures when not in use.
7. Troubleshooting
- No Spark:
- Check if the power adapter is properly connected and the Power Indicator is illuminated.
- Ensure spark plugs are correctly and fully inserted into the sockets.
- Verify the Rotary Switch is not in the "OFF" position and the frequency is set above 0.
- Weak or Inconsistent Spark:
- The spark plug may be faulty and require replacement.
- Ensure the spark plug gap is within the vehicle manufacturer's specifications.
- Compare the spark with a known good spark plug using the dual-hole testing feature to confirm the issue.
