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.
