This device enables technicians to visually inspect and assess the \u003cstrong\u003eignition spark\u003c\/strong\u003e of removed spark plugs outside the combustion chamber. The tester is primarily used for troubleshooting gasoline engines, allowing the spark plug's performance to be evaluated under variable loads to detect wear or defects.\u003c\/p\u003e\n\u003cp\u003eDuring the diagnostic process, the tester generates high voltage itself to simulate the operation of an \u003cstrong\u003eignition coil\u003c\/strong\u003e, after which the \u003cstrong\u003espark strength\u003c\/strong\u003e and continuity are immediately visible. The user inserts the \u003cstrong\u003espark plug\u003c\/strong\u003e into one of five test ports, and the test speed is digitally adjustable between 200 and 9000 revolutions per minute. By adjusting the \u003cstrong\u003esimulated engine speed\u003c\/strong\u003e, the stability of spark discharge at different RPMs can be visually compared with a reference spark plug in the base station, helping identify insulation problems or excessive electrode gap.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display:flex;
