The electronic stopwatch "Integral S-01" is an electronic device with an autonomous power supply and a liquid crystal display (LCD). The principle of operation of the electronic stopwatch is based on the use of a quartz oscillator and microprocessor, which provides operation of the device in all modes and outputs the measurement information to the LCD display.
Electronic stopwatches "Integral S-01" are designed for use in scientific and industrial activities, sports and other areas that require accurate measurement of time intervals.
The device provides operation in two modes - "stopwatch" and "watch". Mode selection and control in each mode is carried out by the corresponding buttons. In the "stopwatch" mode the measurements of time intervals are carried out,
it is possible to enter the results of measurements into the memory (maximum number of measurements - 10), read and erase the results of measurements. The "clock" mode displays the current time on a twenty-four-hour scale in hours, minutes and seconds.
Electronic stopwatches "INTEGRAL S-01" are measuring instruments and are subject to primary calibration in the accredited laboratory of the metrology department of "INTEGRAL" - the managing company of "INTEGRAL" Holding (Accreditation Certificate BY/112 3.0276). Verification interval - 1 year. Information about verification is reflected in the product passport, certificate of verification, as well as on the verification mark (sticker) on the back cover of the device.
Electronic stopwatches "Integral S-01" are registered in the State Registers of Measuring Instruments:

In electronic stopwatches "Integral S-01" there is a possibility of control by external electric circuits. The START/STOP and RESET buttons as well as the "+E" power supply are connected to the connector located under the manhole cover in the rear cover of the device. The connector on the stopwatch board is a PLS2-3 plug. The product includes a BLS2-3 socket connector.
