4. Enstalasyon ak Enstalasyon
Follow these steps for proper installation of your tachometer gauge. Ensure the vehicle's power is disconnected before beginning installation.
4.1 Monte kalib la
- Choose a suitable location on your dashboard or panel for installation.
- Cut a circular hole with an approximate diameter of 52mm (2 inches) at the chosen location.
- Insert the tachometer gauge into the hole.
- Secure the gauge from the back using the provided mounting bracket and nuts.
4.2 Koneksyon fil elektrik
Refer to the wiring diagram below and the provided connecting cable for correct connections. Incorrect wiring can damage the device or vehicle electrical system.

Image 4.2: The included connecting cable harness with color-coded wires for installation.
- Fil wouj: Connect to Battery Positive (+9-32V DC).
- Fil ble: Connect to Battery Negative (-).
- Fil nwa: Connect to Signal Input. This receives the pulse signal from your tacho sensor, engine, alternator, ignition coil, or crankshaft sensor.
- Orange/Yellow Wire: Connect to Backlight Positive (+9-32V DC). This powers the red backlight.
After all connections are made, ensure they are secure and insulated to prevent short circuits. Reconnect the vehicle's power.
5. Operasyon Enstriksyon
The Keenso Digital Tachometer Gauge provides real-time engine RPM and accumulated operating hours on its LCD display.
Imaj 5.1: Gwo plan view of the digital display, clearly showing RPM (Revolutions Per Minute) and accumulated operating hours (H).
5.1 Li Ekran an
- The large digital numbers indicate the engine's RPM (Revolutions Per Minute), typically displayed as "RPM x10" or similar, meaning the displayed value should be multiplied by 10. The indicating range is 0-9990 RPM.
- The smaller digital numbers, usually accompanied by an "H", display the total accumulated operating hours of the engine.
5.2 Power On/Off
The gauge will power on automatically when connected to a 9-32V DC power source and will display readings once an engine pulse signal is detected. It powers off when the power source is disconnected.
6. Antretyen
The Keenso Digital Tachometer Gauge is designed for durability and requires minimal maintenance.
- Netwayaj: Wipe the display and bezel with a soft, damp cloth. Avoid abrasive cleaners or solvents that could damage the surface or anti-fog coating.
- Rezistans dlo: The gauge has an IP67 rating, meaning it is protected against dust and can withstand immersion in water up to 1 meter for 30 minutes. However, prolonged submersion or high-pressure water jets should be avoided.
- Koneksyon: Tcheke koneksyon fil elektrik yo regilyèman pou asire yo rete byen fèm epi yo pa gen korozyon.
NAN. Depanaj
If you encounter issues with your tachometer gauge, refer to the following common problems and solutions:
- Pa gen ekspozisyon/Pa gen kouran:
- Check the power connections (Red wire to positive, Blue wire to negative) for proper voltage (9-32V DC) and secure contact.
- Ensure the backlight wire (Orange/Yellow) is correctly connected if the backlight is not illuminating.
- Lekti RPM ki pa kòrèk:
- Verify the signal wire (Black) is correctly connected to a reliable pulse signal source (tacho sensor, ignition coil, alternator, crankshaft sensor).
- Ensure the signal source is functioning correctly.
- Check for any loose or corroded connections in the signal line.
- Display Flickering or Intermittent:
- Check all wiring for loose connections or damaged insulation.
- Ensure the power supply is stable and within the 9-32V DC operating range.
