P_abs - Absolute Pressure

Enter the absolute referenced pressure and select the associated pressure units directly underneath.

P_baro - Barometric Pressure

Enter the barometric pressure and select the associated pressure units directly underneath. The barometric pressure should be measured at the same location and time as the absolute referenced pressure was measured.

P_gauge - Gauge Pressure

The gauge referenced pressure is calculated by subtracting the barometric pressure from the absolute referenced pressure, and will appear once the required pressure units are selected directly underneath.
