Specification: Item Type: Boat Gauge Panel Material: Metal+Plastic Bottom Hole Size: Approx. 270x145mm / 10.63x5.71in Oil Pressure Switch (low oil pressure ≤0.8kgf/m) Ignition Key: Off: Stop, ON: Power On Product Function: Tachometer, Water Temperature, Oil Level, Voltmeter, Oil Pressure Meter, 7 Color Backlight Tachometer Display Range: 0-30 (RPMx100) Oil Level Display Range: E-F Oil Pressure Display Range: 0-10BAR Water Temperature Display Range: 40-120℃ / 100-250℉ Application: Suitable for yachts, ships, speedboats, etc. Adjustable Speed Ratio: 1. Long press the black rubber button on the instrument for 3 seconds to enter the speed ratio setting mode, release the button for 3 seconds to exit the speed ratio setting mode and save the setting data automatically. 2. After entering the setting mode, press the button, the value increases, release the button, press it again, the value decreases; speed ratio adjustment range: 1-300, 1-12 step value is 0.1, 12-300 step value is 0.5. Adjust the speed ratio value to the desired value, release the button for 3 seconds, and the figures are saved automatically. 3. If your transmitter is mounted on the flywheel, the speed ratio value is equal to the number of engine gears; if the RPM signal comes from the W-point signal, the speed ratio value is equal to half of the electrode plate (number of poles/2). If it is a gasoline engine, the speed ratio is equal to the number of cylinders (cylinders/2). Application: The panel only needs a unit area of 300x190mm to combine 5 instruments together, saving a lot of space, and you can install this instrument panel in your yacht, RV, truck, work vehicle control, and understand the engine status through the data of the instrument at any time Simple Installation Steps: 1. Open the hole on the instrument panel ready for installation 2. Put the instrument into the opening of the instrument panel 3. Fixed with M4 nuts and C type buckles.
