Barometric Pressure
The Analyzer automatically calculates the barometric pressure to within 2% of reading.
To give greater accuracy, the Analyzer allows you to calibrate the barometric pressure
offset by entering the local barometric pressure into the system. The Analyzer uses the
entered value to calibrate the system's barometric pressure offset during future use.
Note
Exercise caution in changing barometric pressure readings; correct
barometric pressure yields more accurate pressure, flow, and volume
readings. Under normal operating conditions, barometric pressure should
not need adjustment.
The Analyzer relies on ambient barometric pressure. Do not set for airport
barometric pressure, which is corrected for altitude.
