4.3 Pemasangan Sensor Kelajuan
Install the universal speed sensor according to its specific instructions, typically near a rotating part of the wheel (e.g., brake rotor bolts) to detect pulses. Ensure a consistent gap between the sensor and the trigger points.
4.4 Tatarajah Awal
After power-up, the speedometer may require initial configuration for wheel circumference and speed pulse settings.
- Wheel Circumference: Measure your wheel's circumference accurately (in mm) and input this value into the speedometer's settings menu. This is crucial for accurate speed and distance readings.
- Speed Pulse Setting: Adjust the number of pulses per wheel revolution based on your speed sensor setup. Refer to the sensor's documentation for the correct setting.
- RPM Pulse Setting: Configure the RPM signal input based on your engine's ignition system (e.g., 1 pulse per 2 revolutions for 4-stroke, 1 pulse per revolution for 2-stroke, or specific coil settings).
5. Arahan Operasi
