Product features:
1. Adjustable frequency, can detect different conditions of the fire
2. Improved design of fire jumping detection table, fire jumping hole away from adjustable knob, safer use
3. With 3 indicators, you can detect whether there is a signal coming, and whether the fire is not adjusted is the instrument problem or the spark plug problem, the judgment is more accurate
4. You can judge whether the spark plug is good or bad, jump the fire straight line is good, and intermittent is a problem
5. You can judge the degree of aging of the spark plug, jump bright purple for good, dark red aging serious
6. You can judge different brands of different specifications of spark plugs, under the same signal, jump fire strong gathering sound loud, vice versa
7. Standard power supply, jump fire is more stable, more resistant to use
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.
Car Spark Plug Tester Using Note:
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.
Car Spark Plug Tester User Manual:
