Electronic stopwatch Integral S-02

Electronic stopwatch Integral S-02 Provides operation in two modes – “stopwatch” and “clock”. Mode selection and control in each mode are performed using the corresponding buttons. in the “stopwatch” mode, it is possible to store measurement results in memory (maximum number of measurements – 30), read and erase measurement results; In the “clock” mode, it is possible to reproduce a 24-hour time scale in hours, minutes and seconds. The operating principle of the stopwatch is based on the use of a quartz oscillator and a microprocessor, which ensures operation in all modes and displays measurement information on the LCD. The stopwatch can be supplied with Russian verification. Manba: https://www.nv-lab.ru/catalog_info.php?ID=9987
