  When the pressure input is fluctuating very much, the display reading will not be 

stable.  To  get  the  more  stable  reading,  averaging  of  pressure  input  data  is 
required. 

  Averaging of pressure input data can be enabled/disabled by selecting YES/NO 

option in  Average Enable menu as shown in figure 31.
