1x 3k RPM Tachometer 1x Installation Instruction

Installation:

1)Press the black rubber button on the instrument for 3 seconds, then it will enter into the speed ratio setup mode, ifthebutton is released for 3 seconds, it will exit the speed ratio setup mode, and automatically retain the setting data. 2)After entering the setup mode, press the button, the value will be increasing, and release the button, then press it again,the number will be decreasing; the adjustment range of speed ratio : 1-300, The stepping value is 0.1 for the range 1-12and 0.5 for range 12-300.Adjust the ratio value to what you want, then release the button for 3 seconds, the digital automatic will automatically save. 3) if your transmitter is installed on the flywheel, the ratio value is equal to the number of the engine gear if the speed signalscome from w point signal, the ratio value is equal to halfelectrodeplate (Poles/2).lf it is the gasoline engine, the speed ratiois equal to the number of cylinders (cylinderi2).
