4.Install Operation
Apply pressure to the pressure transducer,it outputs a electrical signal.
First the corresponding electrical signal will be amplied.and then it will
be converted to digital data by A/D converter.Then the microprocessor
sequentially collects data to modify and correct,the final result will be
displayed on the LCD Display.
