EASY TO OPERATE: Adjustments and settings for speed ratio are straightforward, requiring just a simple button press, allowing users to conveniently adjust according to their needs. It upgrades your car's dashboard with a new and improved gauge panel. Specification: Item Type: Engine Gauge Panel Function: Water Temp + Oil Temp + Voltage + Tachometer Water Temperature Range: 40-120°C Oil Pressure Range: 0-145psi Engine RPM: 0-6000RPM Voltage Range: 8-38V Operating Voltage: DC24V Operating Current: ≤100 MA Operating Temperature: -30°C to +75°C Storage Temperature: -40°C to +85°C Speed Ratio Adjustment: 1. Press and hold 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 the setting data will be automatically saved. 2. In the setting mode, press the button to increase the value, release the button, and then press the button to decrease the value. The speed ratio adjustment range is 1-300, with a step value of 0.1 in the range of 1-12 and a step value of 0.5 in the range of 12-300. Adjust the ratio value to your desired value, and then release the button for 3 seconds, the number will be automatically saved. 3. If your transmitter is installed on the flywheel, the ratio value is equal to the number of engine gears. If the speed signal comes from the W point signal, the ratio value is equal to half of the electrode plate (pole/2). If it is a gasoline engine, the speed ratio is equal to the number of cylinders (cylinders/2). 4. Default Speed Ratio: 138 Main Features: 1. Instrument cluster includes Water Temperature Gauge + Oil Temperature Gauge + Voltage Gauge + Tachometer 2. Equipped with alarm function 3. Automatic/manual switch (engine stops automatically or manually when the temperature is high/pressure is low) 4. With coolant water light that works when the water temperature exceeds 90°C+ S-04 or S-05 5. Engine oil light (on) works when the working pressure is below 0.8kgf/cm2 + S-02 or S-03 Application: The panel only needs a unit area of 200x218mm/7.87x8.58in to combine 4 gauges together, saving a lot of space. The panel is equipped with ignition start switch, light switch, engine stop switch, water temperature alarm, oil pressure alarm, this instrument panel can be installed in your yacht RV truck working vehicle control, through the instrument data at any time to know the engine status.Mode of Operation: Liquid crystal display, stepping motor Application: Used in engine, generator set, RV, yacht, fishing boat, ship, construction machinery, agricultural machinery, modified car and other fields. .
