This code table is a Chinese code table, subject to the actual product!(Picture is in english)Please pay attention to everyone!This code table does not participate in free shipping activities Please be aware
TIPS: As long as the dial has time display, it generally means that the stopwatch is normal.Some car enthusiasts will ask why the time is displayed, but the speed and mileage will not move after it is installed. It is very simple, the position of your probe and the sensor is not right. That point is usually between 5MM-10MM, so you need to find more A few points, if you say that the distance is too small and it can''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''t be done, then you can place something on the wire and try to reduce the distance between the two things.

installation tips:
1. Install the meter head base on the handlebar;
2. Insert the AG13 button battery into the battery slot on the back of the meter
3. Initialize the code table data, generally only need to set the tire circumference as a parameter, then it can be used normally;
3. Insert the meter head into the slide groove of the meter head seat;
4.Install the sensor on the front fork, with the sensor head facing the spokes;
5. The induction magnet is installed on the spokes, aligned with the induction head and spaced apart3-5mmabout;
6. Fix the cables with nylon cable ties;
7. Check whether the above meter head base, sensor and induction magnet are installed firmly. This package comes with necessary rubber gaskets and detailed instructions in Chinese and English to ensure your installation is successful.
8. For more functions, please refer to the manual settings
Setting function
1. Install the battery into the battery slot on the back of the meter;
2. Press the right button within 15 seconds to enter the tire circumference setting;
3. Refer to the wheel diameter and circumference comparison table. For example, the wheel circumference of the 28 model is 224cm, press the left button to set the three-digit value to 224(The machine defaults to 208cm)
4. Right click to confirm;
5. For more functions, please refer to the manual settings.
2 main points of using the stopwatch
1. Hardware installation
Refer to the icon and instruction manual described by the baby
Note: The distance between the magnet and the sensor is controlled by about 4MM
2. Data setting
Refer to the instruction manual for the method of operation
Set wheel diameter(That is, the distance traveled by the speed wheel one revolution, the default value is 2060MM)
set time
Note: Whether the speed is displayed by the stopwatch is accurate, the key is whether the wheel diameter setting is accurate
Reference wheel diameter (the distance the wheel passes through one revolution, in MM, will vary due to different tire pressures)
