Car Spark Plug Test principle:
In automobile ignition system, the high-voltage ignition coil generates a high-voltage (10000 volts or more), and the spark plug diverts it from high -tension ignition coil into the cylinder engine, spark between the spark plug electrodes will ignite the mixture. The Detector could tell the good spark plugs from the bad by the strength of the spark.
1. Please Turn Off Power before you place spark plug
2. The Spark Plug Tester is a high-voltage detector, so do not touch spark plug with hand at work to avoid danger.
The higher the frequency, the stronger the spark strength.
