In the “Gauge Calibration” window, you will see the Test Points for Channel A and Channel B. The
number of points in this list depends on the setting you have chosen for the ATTMA gauge calibration
pre-set pressures in the Settings dialog (see section 1.9.4).
All of the data fields are entered as pressures, in units of Pascals (Pa). Get the values from your
calibration lab report.
Click the button to add additional pressures for which the calibration lab provided data.
The button will reset all targets to the default setting.
The button will clear all inputs and targets, and delete all but one test point.
Once all Test Point data has been recorded, click .
FanTestic will then compute the correction factors for the gauge, save them to your computer’s local
hard drive, and apply them to future pressure readings/recordings on FanTestic using the gauge with the
serial number being calibrated.

area.
4 Manage Pressurization/Depressurization (Data) Sets

on the direction – direction being whether the test was performed to induce pressurization in the
building or depressurization.
