Car Spark Plug Tester, Dual Hole

There are two test holes, which can test two spark plugs simultaneously. If you suspect that the spark plug is faulty, you can make an accurate judgment through the comparison test.

Purpose: To test spark plug performance and ignition strength

Scope of application: 12V gasoline car spark plugs.

Principle of car spark plug testing:

In the car's ignition system, the high-voltage ignition coil generates a high voltage (more than 10,000 volts), and the spark plug discharges it to

A high-voltage ignition coil enters the engine cylinder, and a spark between the spark plug electrodes ignites the mixture. The detector can tell

A good spark plug can be distinguished from a bad one by the strength of the spark.

Precautions for using the car spark plug tester:

1. Turn off the power before inserting the spark plug
2. The spark plug tester is a high-voltage tester. Do not touch the spark plug with your hands when operating to avoid danger.

Instructions for use of the car spark plug tester:

1. Insert the spark plug into test hole 1 or 2. If you want to compare the new and old spark plugs, insert the new spark plug into hole 1 and the old spark plug into hole 2

2. Connect the power supply

3. Turn the key switch 4 clockwise to turn on the tester, light 3 will illuminate, and the tester is now rotating at a speed of 1000 rpm.

4 . Turn the ignition key 4 clockwise again to set the operating frequency between 1000 rpm and 5000 rpm.

The higher the frequency, the lower the spark intensity strong.
