Or disassemble the speedometer and move it with a small screwdriver.So no need to tool rental.
The adjustment method of the speedometer is different according to different models. It is recommended to go to a 4S shop to let a professional operate it. The speedometer is used to check the driving speed of the vehicle. It supports two units: miles per hour or kilometers per hour. The measurement of vehicle speed is realized by the vehicle speed sensor. The driving speed of the car is closely related to the radius of the wheel and the structure of the rotating shaft. Most parts of the car are made of iron. By installing a Hall sensor that can detect changes in magnetic flux at the corresponding position, the output of the sensor will follow the driving of the car. During the process, the rotation of the shaft is constantly changing, and the final speed will be reflected on the instrument panel.
If the speedometer is inaccurate, it can cause some distress to driving and need to be adjusted. The following are the steps to adjust the Auman speedometer: 1. Check the electrical system: first check the electrical system of the Auman speedometer, including whether the connecting wires and fuses of the meter are in good condition, and whether the voltage of the meter is normal. 2. Locate the adjustment screw: Oman speedometers usually have an adjustment screw, usually on the back or side of the meter. A special tool is required to open the instrument cover and find the screw locations. 3. Prepare test tools: Adjusting the Auman speedometer requires the use of test tools, including a speedometer tester and a standard speedometer. A speedometer tester measures the speed of the vehicle while it is in motion, and the standard speedometer is used as a reference. 4. Adjust the screw: use the speedometer tester to measure the speed of the vehicle, and compare it with the standard speedometer. If the displayed value of the Auman speedometer is not accurate, it can be calibrated by adjusting the screw. When adjusting, you need to stop the speedometer first, and then use the adjustment tool to turn the screw until the pointer of the speedometer is consistent with the standard speedometer. 5. Re-test: After adjusting the screw, it is necessary to re-test the Auman Speedometer to ensure the accuracy of the adjustment. It should be noted that if the failure of the Auman speedometer is serious, it is necessary to replace the instrument or find a professional technician for repair. At the same time, adjusting the speedometer requires certain professional knowledge and experience. If you have no experience, it is best to ask a professional to adjust it.
