Full Scale Span(3)

3. Full Scale Span (VFSS) is defined as the algebraic difference between the output voltage at full rated pressure and the output voltage at the

minimum rated pressure.

Response Time(5) (10% to 90%)

5. Response Time is defined as the time for the incremental change in the output to go from 10% to 90% of its final value when subjected to a

specified step change in pressure.
