The line is in the form of the stopwatch." There are three lines of numbers on the screen of the race stopwatch. We are usually called " three row stopwatch," so how can we make it easier to see the stopwatch ? In fact.
The electronic belongs to the electronic sports and fitness equipment. This is a very hot mini sports stopwatch chronograph . In our physical education class, we often see the physical education teacher take it to record the performance of the students' running exercises. The basis of the sports test results, the is also one of the indispensable equip men ts for sports coaches. When we participate in track and field activities, only the referee coach level can often use them. They are of course easy to read and understand the screen in the. data friends, but for infrequent users would not be able to use this, especially novice coach, for them is forced to use, because the is one one of their tools, they often think, how to read a few lines of numbers on it?
According to my cognition, I will discuss how to read the numbers in this screen. You also know how to read the, and how to look at the numbers above. We need to look at the two small numbers in the upper left corner of the. The 30 -stop can simultaneously record the running results of 30 remote mobilizers at the same time, while the shows only 3 lines of numbers. It is impossible to display 30 lines at the same time . If 30 lines are displayed , the will not change very long. Yet? The three-line number displayed by the only displays the time difference between the running of the two athletes reaching the end point on the number of the time being recorded. The time difference is the first line and the second line, and the third line is the time being recorded. Bigger, this third line is the time for the athlete to record the time, and this time is not stopped by pressing the pause button, because we are using a 30 - stop watch , such as 20 colleagues running, we are at the end of their run Usually press the left button to get the grade time. We find that the big row number will not stop, but the second row will jump out of a small number. We will see this and it will be correct . This is the recording the time difference of the athlete running. That is, the time to reach the end of the gap, multi-channel stopwatch is generally like this.
When we recorded the athlete's competition results with, we found that the number was stunned. How do you read this? Tell you! Read time based on the results of this can also be caused by everyday life, we often encounter in their daily lives they say some sort of a few seconds, which is nothing more than hours, minutes, seconds, but the has this precision on the There is often a string of time numbers in the LCD screen of the. How do we distinguish it? We usually know by time, minute, second, and distinction, and the will mark us with a small punctuation mark; in the screen of the electronic stopwatch, the hour unit has a colon of two points ( :) Mark, the unit of the minute is marked with a small('), the unit of the second is the small two (") to mark, and the next few digits are smaller than the second, we are all Read it as time unit of milliseconds → microseconds → nanoseconds → picoseconds.
