Feature: 1. High Accuracy: Engine instrument panel has a high precision measurement function, can accurately monitor the engine's water temperature, oil temperature, voltage and speed, providing reliable data support. 2. Easy to Operate: The adjustment and setting operation of the speed ratio are very simple, just hold down the button to adjust, convenient for users to adjust according to needs. 3. Alarm Function: The instrument cluster has an alarm function, which can remind the user of abnormal conditions of the engine in time to ensure the safety of the engine. 4. Multiple Protection: In addition to the automatic stop function of high temperature and low pressure, there are also cooling water lights and engine oil lights, which can provide a more comprehensive protection mechanism to detect and solve problems in time. 5. Wide Application: Gauge cluster can be used in engines, generator sets, RV, yachts, fishing boats, ships, construction machinery, agricultural machinery, modified vehicles and other fields Specification: Item Type: Engine Gauge Cluster Function: Fuel Level, Water Temperature, Oil Temperature, Voltage, RPM, GPS Speedometer Speed: 0-200 km/h Opening Size: Approx. 270 x 145mm / 10.6 x 5.7in Indicators: Left, High Beam, Right Water Temperature Range: 40-120°C Oil Pressure Range: 0-145 psi Engine RPM Range: 0-8000 RPM Voltage Range: 8-16V Operating Voltage: DC12V Operating Current: ≤100 MA Operating Temperature: -30°C to + 75°C Storage Temperature: -40°C to + 85°C Speed Ratio Adjustment: 1. 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 automatically save the settings. 2. In the setting mode, pressing the button will increase the value, releasing the button and pressing again will decrease the value. The speed ratio adjustment range is 1-300, with a step value of 0.1 for the range of 1-12 and a step value of 0.5 for the range of 12-300. Adjust the ratio value to the desired value and then release the button for 3 seconds to automatically save the value. 3. If the 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 pole 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 Function: 1. Instrument cluster includes Fuel Gauge, Water Temperature Gauge, Oil Temperature Gauge, Voltage Gauge, RPM Gauge 2. Equipped with alarm function 3. Automatic/manual switch (engine stops automatically or manually when high temperature/low pressure occurs) 4. Work with cooling water lamp when the water temperature exceeds 9OC+ S-04 or S-05 5. Engine oil lamp (press) low working pressure 0.8kgf/cm2+ S-02 or S-03 Application: The panel only needs a unit area of 300*190mm to combine 5 instruments together, greatly saving the use of space, and the panel with ignition start switch, light switch, engine stop switch, water temperature alarm, oil pressure alarm, you can install this instrument panel in your yacht, RV truck work vehicle control. The status of the engine is always known through the data of the instrument Mode of operation: liquid crystal display, stepping motor Applicable: Suitable for yachts, RV trucks, etc .
