How to install it ?- Cut an 85mm (3 3/8") hole in the panel and allow a clearance of 55mm (2 3/16”) behind the panel to fit the gauge. - Put the gauge in the hole and screw down. |
How to connect wires ?Yellow wires (backlight) --- Power Positive. Orange wires (backlight) --- Power Positive. Black wires --- RPM Signal. Red wires --- Power Positive. Blue wires --- Power ground. Please note: Tachometer can be connected to 12VDC and 24VDC power directly. |
Why Dont get RPM signal ?Tachometer sometimes cannot get signal by ignition system. So, I suggest Tacho sensor signal. It is more stable. I suggest you can buy a Tacho sensor from Eling Parts. NO. is B07RR8NQ45, B07RN3HJ72. |
How to setting Tach RPM Ratio ?
1. Turn on the power supply first.
2. Press and hold the mode button for 3 seconds to enter the setting speed ratio mode. then adjust speed ratio from 0.5-250 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.
