ELING 85mm GPS Speedometer Odometer 0-200KM/H with Tachometer (0-8000 RPM) - 12V/24V Digital Gauge with Amber Backlight & GPS Antenna - Perfect for Cars, Trucks, Motorcycles & Marine Vehicles

Product Features: -Suitable for all vehicles and off-road vehicles -The signal comes directly from the satellite signal receiver(GPS Antenna), don’t need other speed sensor. -The gauge has the advantages of high precision, quick location confirmation and short start up time. -IP67 waterproof and dustproof grade -Reverse polarity protection and anti-fogging performance -No Stationery Drift -Stepper motors used for full range of stepping gauges, great feature with its less power consumption, longer life, higher precision, etc. Product Introduction How to install it? - Cut an 85mm (3 3/8") hole in the panel and allow a clearance of 55mm (2 3/16”) behind the panel to fit the gauge. - Put the gauge in the hole and screw down. - For the GPS antenna, you should securely fasten it in the flat position, black side upwards, preferably outside (or inside front windscreen) so that it has a clear view of the sky to pick up satellite signal. Connect the antenna cable to socket in the back of the gauge. And do not cut cable. How to Set Odometer? - Press the back button for 2-3 seconds first and then turn on the power supply. - Release the button after seeing “ODO”; Press the button to set up the target odometer value. - After adjustment, release button first, then wait for menu to complete flashing. - Turn off the power supply, then turn on again. Odometer will record the setting. How does GPS Speedometer odometer compensation work? 1. When the device enters tunnel/bridge without no GPS signal, the inside flash memory will record the last valid GPS longitude and latitude. 2. And the device will get valid GPS longitude and latitude again when leaving tunnel/bridge. 3. The CPU inside will calculate the two GPS data to use algorithm to add the lost odometer when in tunnel/bridge. How to be setting Tach RPM Ratio? 1. Press the button for 2-3 seconds first, then turn on the power supply. 2. Release the button after seeing “PULSE”; Press the button to set up speed ratio from 0.5 to 327. After adjustment, release button and wait for menu to complete flashing. 3. After setting, release button and wait for menu to complete flashing., then it will save the setting. 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.

Press the button for 2-3 seconds first and then turn on the power supply. 2. Release the button after seeing “BUZZ”; Press the button to set up the target overspeed buzzer alarm threshold value. 3. After adjustment, release button first, then wait for menu to complete flashing. 4. Turn off the power supply, then turn on again. Odometer will record the setting. ASIN NO. B0836HL863 GPS speedometer keeps counting ? - After installation in the first time, GPS speedometer needs to search for signal, that's the reason that LCD counts numbers all the time. - After getting signal, LCD will come back to 0. It is normal. ASIN NO. B0834PJGYM Why Don't 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. ASIN NO. is B07RR8NQ45, B07RN3HJ72. ASIN NO. B09GLTL1W6 External button wiring ? For the external button, one pin is connected to white wire of meter, the other to power negative/ground.
