-Be suitable for all kinds of tacho RPM sensors, and display the rotation speed of the engine.
-Use moving-magnet principle to drive the needle, featuring good endurance and anti-vibration.
-IP67 waterproof and dustproof grade
-Stepper motors used for full range of stepping gauges, great feature with its less power consumption, longer life, higher precision, etc.
-With curved glass (with anti-fogging function)
-With ultra-wide working voltage design( long-term operating voltage: 9-32V, Maximum up to: 36V (≤ 1 min)).

How to install it?- Cut an 85mm (3 3/8") hole in the panel and allow a clearance of 70mm (2 3/4”) behind the panel to fit the gauge. - Put the gauge in the hole. - Using M4 nut and C type bracket to seal up the gauge. |
How to connect wires?Red wire --- Power Positive. Black wire --- RPM Signal. Orange wire (backlight) --- Power Positive. Blue wire --- Power Negative. 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. |
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 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.
