The application is intended for setting up the magnetic vehicle detection sensor MVS (Magnetic Vehicle Sensor), developed by Svyaz PTK LLC. There is a mode for auto-correction of the sensor reference value for a specified period (from 1 to 50 minutes). Auto-correction operating principle: if during 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 adjusted. In order to enable the auto-correction counter, you must save the reference value to the device memory. If the reference value is not saved, then it is set by the measurement value after 3 seconds after switching on.
