Atmospheric Pressure

For accurate analysis, the application must adjust pressure measurements to account for variations in local atmospheric pressure (barometric pressure).

Enter the current atmospheric pressure or accept the system default of 14.7 psia (0.1014 MPa). When the port is open, it is recommended to enter the value on the low pressure display. It is recommended to enter the current atmospheric pressure daily (or more frequently if atmospheric pressure rises or falls rapidly during the day).

Select Determine high pressure transducer offset to enable the system to determine automatically the high pressure transducer offset.

If the atmospheric pressure is above the entered value and the Determine high pressure transducer offset option is selected, a warning will display.
