2. Press and hold the mode button for 3 seconds to enter the setting speed ratio mode. then adjust speed ratio from 1-300 according to your request.
3. After setting, Data is automatically saved.
4. Please note: If your sensor is installed on the flying wheel panel, the RPM ratio is equal to the number of gears of the engine; If the speed signal takes from W-Terminal, the RPM ratio is equal to the half of the number of poles.
5. Normally, When the engine at idle state, tachometer shows 600-800rpm that means speed ratio is correct. If not, you can turn down or turn up speed ratio to check RPM difference.

This thing is junk. Apparently it doesn't work being wired to the negative side of the coil like every otger tach known to man. The only thing worse than the tach itself are the instructions provided, they are in Chinese and for a speedometer. Stay away

Accuracy of this tach is amazing----I tested it with an electronic function generator before installing in my boat -- it is spot on. I like the feature of being able to set the dial backlight color. Excellent product, I strongly recommend. PS: other reviews are correct....it does not work with a negative tach pulse (I tried it), must be positive. Also watch the wiring---the colors used for power are not US standard....For example, I think ground is blue (not black, as would be expected). No bouncing around of the needle like you can get with other marine tachs. It is a "stepper motor drive", like what is used in automotive tachs and speedometers.

Seems to be working well. I had to hook up my timing light that has a tachometer to dial it in.
