1. 1.0 kPa (kiloPascal) equals 0.145 psi.

2. Device is ratiometric within this specified excitation range. Operating the device above the specified excitation range may induce additional

error due to device self-heating.

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.

4. Offset (VOFF) is defined as the output voltage at the minimum rated pressure.

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.

6. Warm-up time is defined as the time required for the product to meet the specified output voltage after the pressure is stabilized.

7. Offset stability is the product’s output deviation when subjected to 1000 hours of pulsed pressure, temperature cycling with bias test.
