**Test Principle
In
automobile ignition system, the high-voltage ignition coil generates a
high-voltage (10,000 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. **Test Method 1). Place the spark plug on the pedestal
2). Power-on
3).
Press the key switch, the red LED will illuminate and the good spark
plug will generate a strong spark and the bad will generate a faint one
or not . 4). Loosen the key switch, take the spark plug down the tester by pinching the bottom of it. **Accessories 1. 12V linear regulator
2. Operating Manual |
