Calibration
To calibrate,
enter the calibration screen from the main menu:
THE UNIT MUST BE CALIBRATED WITH THE FIRST PULMONARY FUNCTION TEST OF THE
DAY AND AFTER EVERY SIGNIFICANT TEMPERATURE CHANGE.
We additionally recommend that the device is calibrated before each new patient, that is every time the disposable
Mouthpiece is changed.
The following screen is displayed:

CALIB
Start calibration procedure and enter details
(temp., vol. etc.), as detailed on the following
pages. The calibration is accepted when the
actual volume, and the volume calculated
by the SP-2, is within a predefined limit.
When a deviation greater than the limit is
recorded, a message is displayed that the
mouthpiece (screen) must be changed.
VERIFY
Verify calibration. The procedure is exactly
the same as for CALIB (above), but the actual
volume, and the volume calculated by the
SP-2, must be within 3%. If this procedure is
not within 3%, the unit must be recalibrated
using the CALIB option above.
