5. Configuració i configuració

The gauge allows for various parameter adjustments to match your vehicle's sensors and preferences. Use the button on the back of the unit for configuration.

5.1 Parameter Selection Mode

To enter parameter selection mode, press and hold the button on the back of the unit, then power on the gauge. The LCD will display options such as OILP (Oil Pressure), HOUR (Working Hours), UNIT (Measurement Units), PULSE (Tachometer Ratio), OIL (Fuel Gauge Signal), and ATER (Water Temperature Signal).

• OILP - Oil Pressure: Select the appropriate oil pressure sensor range (e.g., 0-5Bar/0-72.5PSI or 0-10Bar/0-145PSI).
• HOUR - Working Hours: Adjust the digital part of the working hours. Measuring range is 0-99999.9 hours.
• UNIT - Set Units: Configure units for water temperature (°C/°F) and oil pressure (PSI/BAR).
• PULSE - Set Tach Ratio: Adjust the tachometer pulse ratio (e.g., P100 for 1 pulse/round). Measuring range is 0-39999.
• OIL - Set Fuel Gauge Signal: Select the correct fuel level sensor resistance (e.g., 0-190Ω, 0-180Ω, 10-180Ω, 240-33Ω, 240-30Ω).
• ATER - Set Water Temperature Signal: Choose the water temperature sensor resistance (e.g., 291.4-22.4Ω or 301-23Ω for 40-120°C/104-248°F).

Refer to the video in the Installation section for a visual guide on accessing and adjusting these parameters.

6. Instruccions de funcionament

Once installed and configured, the gauge will display real-time data for all six functions. The GPS speedometer will automatically acquire satellite signals to display speed. The tachometer will show engine RPM based on the configured pulse ratio. Other gauges will display readings from their respective sensors.

6.1 Característica impermeable

The gauge is IP67 waterproof, meaning it can withstand immersion in water up to 1 meter for 30 minutes. This makes it suitable for marine environments.

7. Manteniment

The MAIMEIMI 6-in-1 GPS Speedometer is designed for durability and requires minimal maintenance.

• Neteja: Wipe the display and bezel with a soft, damp drap. Eviteu productes de neteja o dissolvents abrasius.
• Inspecció: Periodically check wiring connections for tightness and corrosion, especially in marine environments.
• Comprovació del sensor: Ensure all connected sensors (fuel, water temp, oil pressure) are free from debris and properly seated.

8. Solució De Problemes

If you encounter issues with your MAIMEIMI 6-in-1 GPS Speedometer, consider the following troubleshooting steps:

• Sense alimentació/pantalla:
  • Check the power supply (Red wire) for 9-32V DC.
  • Verify the ground connection (Black wire).
  • Ensure all wiring is securely connected.
• Lectures inexactes:
  • Velocímetre: Assegureu-vos que l'antena GPS tingui una visió clara view del cel.
  • Tacòmetre: Verify the PULSE setting matches your engine's specifications. If unsure, consult your engine manual or contact support.
  • Fuel Level/Water Temp/Oil Pressure: Check the sensor connections and ensure the gauge's settings (OIL, ATER, OILP) match the installed sensors.
• Display Issues (e.g., hard to see in sunlight): While the unit features a TFT screen, extreme direct sunlight can sometimes affect visibility. Try adjusting the viewing angle or providing shade if possible.
• Funció d'alarma: Ensure all alarm thresholds are set correctly in the configuration mode (if applicable, not explicitly detailed in provided features but implied by "with alarm design").

If problems persist after following these steps, please contact MAIMEIMI customer support.
