Automotive Spark Plug Tester Detector - Two Hole Spark Plug Analyzer Diagnostic Tool

feature: 1. The frequency is adjustable, which can detect the firepower adjustment of different working conditions 2. The design of the bypass detection table is improved, and the bypass hole is far away from the adjustable button, which is safer to use. 3. With 3 indicator lights, it can detect whether there is a signal coming, whether the fire is not fixed is the problem of the instrument or the spark plug, and the judgment is more accurate 4. You can judge the quality of the spark plug, the spark straightness is good, and there are intermittent problems 5. The aging degree of the spark plug can be judged. The sparklings are the best bright violets, the dark reds poorly aged. 6. Spark plugs of different brands and specifications can be judged to have strong flashover and loud sound under the same signal, and vice versa. 7. Standard power supply, more stable flashover and more durable use 8. With European standard adapter Automobile spark plug testing principle: In the car ignition system, the high voltage ignition coil generates high voltage (above 10000 volts), the spark plug transfers it from the high voltage ignition coil to the cylinder engine, the spark between the spark plug electrodes will ignite the mixture. can distinguish by the strength of the spark between good spark plugs and bad spark plugs. Precautions for using automobile spark plug tester: 1. Please turn off the power before placing the spark plug 2. The spark plug tester is a high voltage detector. Do not touch the spark plug with your hands during work to avoid danger. The higher the frequency, the stronger the spark force. Auto Spark Plug Tester User Manual: 1. Put the spark plug into test hole 1 or 2. If you want to compare the new spark plug with the old one, put the new spark plug into hole 1 and the old spark plug into hole 2 2. Plug in the power 3. Turn key switch 4 clockwise to turn on the tester, indicator light 3 is on, and the tester runs at 1000 rpm/min. 4. Turn key switch 4 clockwise again to adjust the working frequency between 1000 rpm and 5000 rpm/min.
