Magnetic field tester, detector With this detector, it is easy to check which electromagnetic component (actuator) is defective. Among others, ignition coils (conventional, double-spark coil, single-spark coil), alternator, interior blower, duo valve (for heating, cooling water), valve for EGR control (valve for exhaust gas regulation), injectors (injection nozzles), spark plugs, Hall sensors and relays can be tested. The detector is held above the electrical component to be tested. An acoustic signal and illuminated LEDs indicate the functionality of the component. The tip of the detector has two sides. Both sides, "diamond" and "circle", have a different sensitivity depending on the type of actuator. To obtain an accurate result, the detector tip should be held over the coiled area of the electronic component. The detector also has an on/off switch. Level II is for normal use and level I is for components with a very strong magnetic field. Main colour grey Application testing Type acoustic Type/kind Item
