Reminder: The principle of the code table is simple. When installing, pay attention to the distance between the magnetic sensor and the magnet as close as possible. It must be within 2 mm to ensure the accuracy of the watch. If the distance is not enough, place something under the magnetic sensor. can. In addition, friends of the disc brake must pay attention to the installation, the magnetic sensor should be installed on the side without the disc to avoid the problem of too far installation distance, which affects normal use. When installing the computer, be sure to pay attention not to pull the cable too tightly, leave a margin for the handle and shock absorber, otherwise the cable will be easily broken and the cable will not be guaranteed. The Sigma series watch head is only for life waterproof, please take it out when it rains as much as possible. The head of the meter is not damaged by man-made, do not enter the water, the warranty is one year, and the return shipping is borne by the buyer.
Sigma is only limited to life waterproof, it is best to avoid contact with water, if it is raining, do not press the keys and wait for the water to dry Press again, don’t knock off the rubber ring behind the watch when installing the battery, it is for waterproof.
We are already losing money online to make a reputation for the price, no bargaining, no free shipping, no gifts, please understand
Notes for computer installation:
1. Pay attention to the side with the Sigma logo on the watch seat, which faces the direction of the car when installing
2. Pay attention to the distance between the sensor and the magnet. It should be about 2 mm, the closer the better, as long as you don’t touch it.
Cadence installation notes:
1. The installation distance between the cadence sensor and the magnet should be 2 mm, the closer the better.
2. The cadence cable and the plug under the meter base should be inserted in place, and the plug must be inserted hard to make good contact. The plugs are not divided into left or right.
3. The cadence display must be adjusted to the CADENCE display state, and the cadence value will be displayed during riding.
Guaranteed original authentic products, Sigma China Shenyang general agent products, I have been the agent of this product for more than three years
sigma:
The most well-known and most widely applicable stopwatch brand in mainland China has a subtle appearance, exquisite workmanship, and high, middle and low grade products. The most famous is the BC series. There are several products from BC400 to BC1600, with more functions according to product codes. The common BC series products on the market are 500/600/800/1200/1600/.

What is a code table
The computer is an electronic product installed on the bicycle to display a number of cycling data, such as current speed, cycling mileage, cycling time, etc. The high-end computer also has altitude, air pressure, and slope displays.
The code table is generally composed of the following components:
1. Header: Looks like an electronic timer, with LCD screen, buttons, metal contacts, etc., is the most important part of the chronograph.
2. Table base, Wiring and sensor: The meter base is usually placed on the handlebar or stem of the car to fix the meter head. There is a wire on the table base of the wired digitizer, which connects the table base with the sensor installed on the front fork. The wireless code meter is not connected, and the sensor transmits data to the meter head by transmitting a wireless signal.
3. Induction magnet：It is installed on the spokes of the front wheel, and the position keeps the corresponding relationship with the sensor installed on the front fork. The meter head calculates the speed and other data through the time interval between the induction magnet passing the sensor twice.
4. Cadence（Non-standard accessories）: The mid-to-high-end computer has the function of calculating the cadence, that is, the frequency of the rider''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s pedaling. Common cadence devices include cables, sensors and induction magnets. The cables are used to connect the meter base and the sensor installed at the rear triangle of the frame（The back triangle here refers to the pipe parallel to the central axis）, The induction magnet is often installed at the crank, the position corresponds to the sensor, and the working principle is the same as before.
When the rim rotates, the sensor captures the information brought by the induction magnet and transmits it to the computer through the sensing line. The computer computer processes this information and calculates the speed, mileage and other information.
In layman''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s terms:A magnet-like thing is installed on the front wheel, and a sensor is installed on the front fork. When the wheel rotates, the magnet will pass by the sensor once, and the computer will count one revolution. According to the preset wheel parameters, the code The watch calculates the speed and distance.
During cycling, we will often encounter uphills and downhills, or riding on flat roads because we can’t master the riding rhythm and get burst, or we can’t master the cadence speed and the rhythm is disrupted , The heart rate cannot be controlled because of the high or low speed. At this time, the function of the stopwatch is reflected. It can provide you with a complete set of real-time data, let you know what state your body parameters are in, and prepare for sending at any time. Power and so on in various situations!
