4. Make sure to completely bleed out the pressure inside HPFM CAT, and confirm that with pressure gauge reading.
5. Click OK to start set-zero (See the screen above.) Once hearing a beep, start increasing the pressure
inside HPFM CAT by turning the air valve to Air Flow In position.
6. Stop pressuring at 550 kPa by turning the air valve to Closed position.
7. If there is any unsatisfactory data collected, you can check Set Ignore Points box and high light those
points (shown in dark color.) You can also remove these highlighted points a, b, c, d, by clicking on DEL button.
Normally a 1st order regression will remove dP offsets across the range of a transient data sets.
a. To Ignore points check the Set Ignore Points Box in the bottom left hand corner, and then
select the points you want to ignore.
b. To delete points, select the points you want to delete and click DEL .
c. To retrieve deleted points click on the UNDO button in the bottom right hand corner.
d. To undo the regression select the UNDO button in the bottom left hand corner
8. You may increase Order to 2 and click on REG button to perform a regression. A new window will pop up to
indicate the regression result. Click Yes to save it.
9. Saved set-zero results applied to all subsequent transient dP calculations. Removing drift or temperature
changes to the pressure sensor readings. Set-zero regressions can be seen in the data viewer.
