If not it will be autoset to default value input ushort dp_limiter =100; // Number of data points input uint endpos =0; // Last value position input double multStdDev =1.96; // Bands separation input inputs_switch comments =On; // Comments switch input inputs_switch record =Off; // Record info into a file text
