The application is designed to configure the MVS (Magnetic Vehicle Sensor) magnetic vehicle detection sensor, developed by Svyaz PTK LLC. The mode of auto-correction of the reference value of the sensor for a specified period (from 1 to 50 minutes) is provided. The principle of operation of auto-correction: if for the selected period the average value of the last 6 measurements has changed by more than 1/3 of the response threshold, but less than the response threshold value, the reference value is corrected. In order to enable the auto-correction counter, it is necessary to save the reference value in the device's memory. If the reference value is not stored, then it is set to the measurement value after 3 seconds after switching on.
