Wrap Induction Wire 5-6 Turns TIGHTLY Around the SPARK PLUG WIRE

No Ground Wire Required

The induction wire can be cut off to shorten the length and can also be attached another wire to extend the length (Max100m/328 ft.), any common insulated wire is fine. It will not affect the operation

If the signal is not strong enough, you can add one wrap at a time until the signal is clear. The signal strength is controlled by the number of wraps (Too many wraps will pick up electronic noise and give a faulty reading).

1 The actual firing pattern for a portion of 4 stroke 1 cylinder engine is 1 Spark Per Revolution, So you should set the firing pattern to 1P1R instead of 1P2R. Most single cylinder air cooled engines idle around 1400 RPM, if the RPM displayed too low, Set the firing pattern to 1P2R; If the RPM is too high, set more sparks per revolution, such as 2P1R, 3P1R...

1P2R / 1P1R

To Set Engine Firing Pattern: Press and Hold “MENU” button until default firing pattern“1P1R” starts flashing, release and press either “MENU” or “SET” button, the LCD will display 1P1R 1P2R2P1R 3P1R 3P2R 4P1R 5P2R and 6P1R separately. Once you find your desired Spark Plug firing pattern, release the button, the LCD will blink for 10 seconds and return to total hours, you are done.

1P1R means Spark Plug Fires ONCE PER REVOLUTION( Default Engine firing Pattern )

To View Engine Firing Pattern: Press “MENU” button 5 Times

Skip if RPM is correct, the default setting (1P1R) should work for most engines.Engine Firing Pattern = Spark Plug Firing Revolution
