This high-precision tachometer is the ideal instrument for monitoring your engine's performance. Made of robust aluminum and ABS, it is suitable for a wide range of applications such as outboard motors, construction equipment, motorcycles, and automobiles. It features a stepper motor that drives the needle for an accurate engine speed (RPM) reading, ensuring high accuracy, simple operation, and control. The LCD screen clearly displays the time, is anti-glare, and remains perfectly readable from all angles. Boasting excellent anti-fog functionality and an IP67 rating, its housing is completely waterproof. Installation and wiring are very simple, saving you time and effort.

**Wiring:**

- Black Wire: Power Negative (-)

- Red Wire: 9-32V DC Power Supply

- Blue Wire: RPM Signal

- Yellow Wire: Backlight

- White Wire: Adjustment

**Operating Instructions:**

1. Touch the white wire to the negative terminal for 3 seconds to enter gear ratio adjustment mode. Release the contact for more than 3 seconds to exit adjustment mode.

2. In adjustment mode, maintaining contact between the white wire and the negative terminal increases the value. Releasing and re-applying it decreases the value. The longer the contact, the faster the count.

The minimum increment is 0.1, with an adjustable range from 1.0 to 360.

3. Once the ratio is adjusted to your liking, leave the white wire disconnected from the negative terminal. After 3 seconds, the tachometer will automatically save your setting. If the result is not satisfactory, reset it.
