          *1 Less stable zones of approx. 2% of F.S. exist at both ends of the detecting range.
          *2 The variation of sonic velocity in air generates errors in the negative direction at 25°C at 77°F and above, or in the positive direction at 25°C at 77°F and below.
          *3 The errors for the indicated value at 25°C at 77°F.
