• The frequency is adjustable, which can detect the fire 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 fire is not adjusted is the problem of the instrument or the problem of the spark plug, the judgment is more accurate

• It can be judged whether the spark plug is good or bad, the straight line of the spark is good, and the intermittent is a problem

• The aging degree of the spark plug can be judged. It is better for the spark to be brilliant purple, and the dark red is badly aging

• It can be judged that the spark plugs of different brands and different specifications, under the same signal, it is better to have a sharp flashover and a loud sound, 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.
