• The frequency is adjustable, which can detect the ignition adjustment of various working conditions
• The design of the flashover detection table is enhanced, and the flashover hole is far away from the adjustable knob, which is safer to use
• With 3 indicator lights, it can detect whether there is a signal coming, whether the ignition not being adjusted is an instrument problem or a spark plug problem, and the judgment is more accurate
• It can be judged whether the spark plug is good or bad. A straight spark line is good, and an intermittent one indicates a problem.
• The aging degree of the spark plug can be judged. A brilliant purple spark is better, while dark red indicates severe aging.

• It can be judged that for spark plugs of different brands and specifications, under the same signal, a sharp flashover and a loud sound are better, and vice versa.

How To Use:

• 1. Put the spark plug in test hole 1 or 2. For comparison, put the new spark plug in hole 1 and the old spark plug in hole 2.
• 2. Connect the power supply.
• 3. Turn the key switch 4 clockwise to turn on the tester, the indicator light 3 is on, and the tester works at 1000rpm/min.
• 4. Turn the key switch 4 clockwise again to adjust the working frequency between 1000 rpm to 6000 rpm.

Note:

• 1. Please turn off the power before placing the spark plug.
• 2. Do not touch the spark plug with your hands during work to avoid danger.
• 3. The higher the frequency, the stronger the spark intensity.
