*RSS

Root Sum Squared for Non-Linearity, Hysteresis, Repeatability

**FSO

The algebraic difference between full scale pressure output value and the maximum pressure output value.

***Calibration

Calibration is performed at ambient temperature of 21°C (70°F). Maximum thermal error was calculated from this datum.

Pressure reference temperature = 0°C (32°F)
