What Is a Stop Watch?
A stop watch is a type of measuring instrument used when time needs to be measured during various experiments or evaluations, and its functions are similar to those of a stopwatch.
Generally, it can measure time from 0 seconds to 60 minutes in increments of 1/100th of a second.
There is a start button to start measurement, a stop button to end measurement, and a reset button to clear the timed time.
The time is incremented when the start button is pressed, or conversely, the time is counted down from a preset time and an audible alarm sounds when the time reaches 0 seconds.
Some types of timekeepers have a dial knob for an easy time setting.
Uses of Stop Watches
One example is troubleshooting, for example, when designing a product. If a defect is known to occur for a certain period under certain conditions, there are cases where the duration of the defect needs to be measured as accurately as possible.
In many cases, the time of duration of a defect is measured by checking with the human eye, pressing the start button at the start of the defect symptom, and pressing the stop button at the end of the defect symptom, so not very high accuracy can be expected. However, it is possible to obtain data with a certain degree of accuracy by repeating the measurement several times and taking the average.
This time may be a delay time in the circuit or response time, and can be used as a starting point to determine which part of the circuit is defective.
Principle of Stop Watches
In addition to the battery and quartz crystal, the stop watches consists of a liquid crystal display and a system on chip (SoC) that divides the oscillation pulses of the quartz crystal, counts them, and displays them on the liquid crystal display.
When a button on the main body of the stop watches are pressed, this signal is transmitted to the SoC, which checks whether the button is a start, stop, or reset button, and if it is a start button, starts timing, if it is a stop button, stops timing, and if it is a reset button, clears the internal timekeeping The start button starts timing, the stop button stops timing, and the reset button clears the internal timing data.
The crystal unit is the core of the system. This device generates an oscillation frequency by applying a voltage to the device, which is a fixed vibration determined by the shape of the crystal.
Commonly used oscillation frequencies are in the range of several hundred KHz to a hundred MHz. The accuracy of the oscillation frequency is about 0.001%, about 1,000 times higher than that of ceramic resonators. The price is also higher than that of ceramic pendulums.
A 32.768 KHz crystal is used for timekeeping. The primary oscillation frequency is divided to produce one second, which is used to mark time.
