Performing a Calibration
1.
Go to the Spirometer Calibration initial screen (
Figure 9
).
You can get to this screen in either of two ways:
•
At prompt
Press
in response to the Calibrate Now? prompt, which appears the first
time you press the Spirometry key each day (as described in
•
Anytime
Press the Menu key
, then choose Spirometry Settings > Calibration
Settings > Calibrate Spirometer.

2.
Fill in all fields.
•
Transducer lot and “cal” codes appear on the transducer package label, as shown
in
Figure 10
.
•
For the syringe volume, see the sticker on the calibration syringe.
•
Update the temperature, humidity, and pressure. See your local weather reports.
The temperature must be 10
°–40° C, 50°–104° F. The atmospheric pressure must
be 600–1100 mbar, 450–825 mmHg, 18–32 inHg, 60–110 kPa.
WARNING To avoid the risk of cross-contamination, always use a new flow
transducer when calibrating the spirometer. Observe all safety information that
came with the flow transducers.
Note
When you open a new package of flow transducers, disregard the calibration CD
that is shipped with them. The CP 200 spirometer does not use the calibration file
on this CD.
Note
To learn how to change the pressure units, see
