How to adjust the time of the watch
In this age of promoting health, many people cannot do without exercise. A good sports watch is very important when exercising. Today, let's learn how to adjust time with a sports watch!

How to adjust the time of sports watch?

1. First, we will enter the date adjustment by pressing the left button three times. When you press the left button twice, the stopwatch and timer should appear in turn.

Then we press the button in the lower right corner again until the time is adjusted.

Finally, we press the button in the upper right corner to change the number and adjust it to the exact time. This completes the time adjustment of the electronic watch.

Time adjustment method of sports watch

The button of a sports watch will light up as soon as you press it, and then press it for a long time until the number flashes. That's an hour hand. When you press it, it lights up. Then press the minute hand for a long time and it will flash, adjust it by the minute alone, and so on, followed by the month, the day and the second hand.

Function introduction of sports watch

1. pedometer watch

The motion sensor of pedometer watch is a 3D acceleration sensor, which can sense the three-dimensional motion acceleration generated by human motion, such as walking and running, so as to record the number of steps in a unit time. Calculate the movement speed and distance of human body through the input step size, and calculate the calories burned through the input weight. Its advantage is that it can be used for outdoor and indoor sports, is not affected by the weather, is very energy-saving, and can store sports data for several days.

2.GPS watch

The GPS watch calculates the moving distance per unit time and the moving speed by receiving the waypoint of the satellite position signal. The accuracy of position signal is determined by the strength and sampling rate of satellite signal. For example, the accuracy of 1 sec sampling rate is obviously higher than that of 60 sec sampling rate. However, too high sampling rate will lead to too fast battery consumption. Its advantage is that it can record the trajectory of movement and synchronize with the map.

3. Heart rate watch

Heart rate watch measures the heart rate of human body by sensing the heart current of human body. The heart rate of human body is different under different exercise intensity. Internationally, the percentage of exercise heart rate to the maximum heart rate is divided into lightweight activities: 50-60%, aerobic exercise 60-75%, endurance training 75-85% and intensity training 85- 100%. Choosing different heart rate regions can achieve different training effects.

How to choose a sports watch

1. Waterproof grade

For the third iron standard, waterproof effect is undoubtedly one of the necessary and sufficient conditions. During cross-country running, marathon and daily training, it often rains or sweats. There are two common waterproof grade signs: ATM and IPX. It is suggested that marathon and cross-country rice should reach at least 3 ATM or IPX-5, and iron rice should reach 10 ATM or IPX-8.

2. Speed and accuracy of searching for stars

The accuracy of the speed and trajectory of searching for stars depends on the number and sensitivity of antennas, the number of satellites that can be searched, whether there are pre-stored ephemeris in the watch, and whether there is a star searching acceleration function with the help of app. Imagine that you fired a gun at the beginning of the 30 thousand marathon, but your watch didn't have time to find the stars. What a disappointment.
