4. Operating Instructions and Parameter Setting

4.1 Entering Parameter Setting Mode

To configure the gauge parameters:

1. Press and hold the button located on the back of the gauge.
2. While holding the button, power on the gauge.
3. The LCD will cycle through the following menu options: OILP, HOUR, UNIT, PULSE, OIL, ATER.
4. Release the button when the desired menu option appears to configure that specific parameter.

4.2 Parameter Configuration

Once in a specific parameter's setting mode, use the button to adjust values.

4.2.1 OILP (Oil Pressure) Setting

The LCD will display "S 00000" (ohm range 10-184Ω). Press the button to cycle through the target ranges based on Table A. Release the button and wait for the menu to complete flashing to save the setting.

4.2.2 HOUR (Working Hours) Setting

The LCD will display "00000.0" (0 hours). Press the button to set the target value. The measuring range is 0~99999.9 hours.

4.2.3 UNIT (Water Temperature & Oil Pressure Unit) Setting

The LCD will switch between °C, °F, PSI, and bar. Press the button to choose your desired unit. Release the button and wait for the menu to complete flashing.

4.2.4 PULSE (Tach RPM Ratio) Setting

The unit for Tach RPM Ratio is 0.01 pulse/round (e.g., 100 indicates 1 pulse/round). The LCD will display "P2000" (meaning 20 pulses/round). Press the button to change the value from 0 to 39999. Release the button and wait for the menu to complete flashing.

4.2.5 OIL (Fuel Gauge Signal) Setting

The LCD will display "O000002" (ohm range 10~180Ω). Press the button to set the target ohm range based on Table B. Release the button and wait for the menu to complete flashing.

4.2.6 ATER (Water Temperature Signal) Setting

The LCD will display "t 00000" (ohm range 291.4~22.4Ω). Press the button to set the target ohm range based on Table C. Release the button and wait for the menu to complete flashing.

Important Note: After setting any parameter, you must disconnect both Power+ and GND cables, and then reconnect them. This action saves the settings. If you only disconnect Power+, the settings will not be saved properly.

5. Maintenance

The ELING 85mm 6 in 1 Multi-function Tachometer is designed for durability and requires minimal maintenance. Keep the display clean using a soft, damp cloth. Avoid using harsh chemicals or abrasive materials that could damage the screen or bezel. Ensure all electrical connections remain secure and free from corrosion.

6. Troubleshooting

If you encounter any issues with your gauge, please check the following:

• No Power/Display: Verify that the IGN+ and GND connections are secure and receiving the correct voltage (12V/24V).
• Incorrect Readings: Ensure that the sensor signals (RPM, TEMP, Oil Pressure, Fuel Gauge) are correctly connected and that the parameter settings (OILP, PULSE, OIL, ATER) match your specific sensors. Remember to save settings by disconnecting and reconnecting power.
• Buttons Unresponsive: Check the external button connection.

For persistent issues, please refer to the wiring guide and parameter setting instructions carefully. If problems continue, contact ELING customer support for assistance.
