Follow these steps for proper installation of the tachometer:

1. Орнату тесіктерін дайындаңыз: Open a 3-3/8 inch (85mm) diameter hole in your dashboard or mounting panel. Ensure there is at least 2-3/4 inches (70mm) depth behind the panel for the gauge body.
2. Insert the Gauge: Carefully insert the tachometer into the prepared hole.
3. Secure the Gauge: Use the provided U-shaped mounting bracket and nuts to fasten the gauge securely from the rear of the panel. Tighten the nuts until the gauge is firm but avoid over-tightening.

6. Электр схемасы

Refer to the wiring diagram below and the provided owner's manual for correct electrical connections. Ensure all connections are secure and insulated to prevent short circuits.

• Қызыл сым: Connect to +9-32V DC power supply.
• Қара сым: Connect to Ground (-).
• Көк сым: Connect to Tachometer Signal Input. This signal can be sourced from the engine's ignition coil, crankshaft sensor, or a dedicated tacho sensor (sold separately, e.g., ASIN B07RN3HJ72 or B07RR8NQ45).
• Қызғылт сары сым: Connect to Backlight (+).

The tachometer is suitable for both diesel and gasoline engines. The signal input method may vary depending on your engine type.

7.1. Speed Ratio Adjustment

The tachometer requires a speed ratio setting to accurately display RPM. This ratio is adjustable from 1 to 300. The default idle speed is typically 600-800 RPM.

1. Орнату режиміне кіріңіз: Press and hold the back button located on the rear of the tachometer for 3 seconds. The display will show the current speed ratio setting.
2. Adjust Ratio: While in setup mode, press the button repeatedly to increase the ratio value. The value will increment by 0.5 with each press.
3. Параметрді сақтау: Once the desired ratio is displayed, release the button for 3 seconds. The tachometer will automatically save the new setting and exit setup mode.

Ескерту: If your tachometer signal is derived from the flywheel, the ratio value should correspond to the number of engine gear teeth divided by two (Poles/2). If the signal comes from the ignition coil in a gasoline engine, the ratio should be set to the number of cylinders divided by two (Cylinder/2).

7.2. Hour Meter Function

The tachometer includes an integrated hour meter that continuously records the total operating hours of the engine. This hour meter cannot be reset.

8. Ақаулықтарды жою

If you encounter issues with your tachometer, consider the following general troubleshooting steps:

• Қуат/дисплей жоқ: Check all power connections (Red wire to +V, Black wire to Ground). Ensure the operating voltage 9-32 В тұрақты ток шегінде.
• RPM көрсеткіші дұрыс емес: Verify the speed ratio setting. Adjust it as described in Section 7.1. Ensure the signal input (Blue wire) is correctly connected to a reliable RPM signal source (ignition coil, crankshaft sensor, or tacho sensor).
• No RPM Movement: Confirm the signal wire is properly connected and receiving a signal. If using a tacho sensor, ensure it is functioning correctly.
• Үзіліссіз оқулар: Check for loose or corroded connections. Ensure the signal wire is not experiencing interference.

For persistent issues, consult a qualified technician or contact ELING customer support.
