6. The unit will then prompt the user to enter the standard conditions value for the m
variable of the calibration orifice. This information can be found with the calibration
data provided with the orifice. Press the “ENT” key to continue. The value of the
last calibration orifice is displayed by default. And example screen is shown below.

7. The unit will then prompt the user to enter the standard conditions value for the b
variable of the calibration orifice. This information can be found with the calibration
data provided with the orifice. Press the “ENT” key to continue. The value of the
last calibration orifice is displayed by default. And example screen is shown below.

8. The unit will then prompt the user for the starting orifice pressure. This defaults to a
value of 70.0 inH
2
O. During the automatic calibration process, the unit will subtract
10.0 inH
2
O to get the target orifice pressure for the next data point. For a starting
pressure of 70, the calibration points will be 70, 60, 50, 40, and 30. Pressing the
“ENT” will begin the automatic calibration process. And example screen is shown
below.
