SPARK PLUG TESTER: This is a digital high frequency tester for testing the performance and strength of spark plugs. If you suspect any spark plug works improperly you could compare and test to make accurate judgment.
FIVE TESTING HOLES: Our car spark plug detector has 5 testing holes, allowing you to test 5 spark plugs simultaneously, improving your test efficiency, saving time and money. It is compatible with most crankshaft engine and motorcycle 11mm spark plug.
SIMULATING REAL SPEED: Unlike other products that can only up to 6000rpm, our tester operating frequency can up to 9000 rpm, simulate real rpm with high accuracy, which greatly improve the test accuracy and work efficiency.
DIGITAL DISPLAY SCREEN: Our updated spark tester uses up and down buttons and equipped with digital display for more precise and convenient control. Each test hole has a corresponding indicator light indicating the status of the spark plug.
THREE-YEAR WARRANTY: No need to worry about after-sales problems, there are 3-Years Warranty of the main unit from the date of you received the AUTOOL product and 1-Year Warranty for accessories. Please contact our after-sales technical team for any product problems.
Car Spark Plug Test Principle: Inautomobile ignition system, the high-voltage ignition coil generates ahigh-voltage (10000 volts or more), and the spark plug diverts it form high-tension ignition coil into the cylinder engine, spark between the spark plugelectrodes will ignite the mixture. The Detector could tell the good sparkplugs from the bad by the strength of the spark. How To Use: 1.Insert the new spark plug into the FIRST hole on the left(Indicator sign:normal light), and insert the old spark plug into the other holes(Indicatorsign: tester light). 2.Plug the power adapter into the power port on the right side of the host andthe indicator light will go on. 3.Turn on the power switch and press the up and down buttons to adjust theoperating frequency. The higher the frequency, the stronger intensity of thespark plug. Notice: 1.Do not pull out or insert the spark plug with the power supply connected. Ifyou want to insertor pull it out, please turn off the power first. 2.When the spark plug is running, the voltage can reach tens of thousands ofvolts, so don't touch it directly with your bare hands to avoid injury. 3.Only the spark plug tester, the spark plugs are not included.
