This picture shows the main calibration page for a PFT Station before it has been calibrated. Once calibrated, the
"Last Calibration" will indicate when the signal was last calibrated, and the "Effective Range" will indicate the last
effective range determined during calibration.
When you calibrate, it is important that the flow calibrations be performed in the order
presented on the calibration page. You must calibrate FRC Flow first, followed by Flow, and then
High Flow last.
If preamplifier adjustments to the Flow preamplifier are necessary, you should do so only during
the calibration of the FRC Flow. If you need to adjust the preamplifier gain during the Flow or
High Flow calibration, you must repeat calibration of the other flow leads.
You can calibrate the Lung Pressure at any time, and same is true of the Pleural Pressure (if you have that
optional signal).
Typically, the first time you calibrate, you will need to adjust the preamplifier which will not be necessary for
subsequent calibrations. Because of this, your first calibration will take more time. But afterwards, you will be
able to run through this very quickly, usually making no preamplifier adjustments and only applying the calibration
standards.
