IQmark Digital Spirometer Operation Manual<br />
Clicking on the handle will display the following calibration screen.<br />
Calibration Screen<br />
Check to see if Sensor: Ready is displayed in the upper right hand corner of the graph<br />
window. If you are using a Spirometer with a COM connector (DB9) with a model/serial<br />
number beginning with 51xxxx, you must place the DPM in the handle to turn it on.<br />
Please note that the handle will remain on whenever the DPM is inserted. Be sure to<br />
remove the DPM after calibration or testing to conserve the life of your batteries.<br />
Barometric Pressure<br />
The Pressure must be set prior to the first time you calibrate the system. It must be<br />
changed only if you change the location of the instrument and the altitude changes. Click<br />
the Settings button to open Spirometry Settings. Select the Calibration tab and enter<br />
the Barometric Pressure in the Default Barometric Pressure box. If you do not know the<br />
barometric pressure, you can select Calculate Barometric Pressure From Altitude and<br />
enter your altitude. The software will automatically calculate and store the usual<br />
barometric pressure for that altitude.<br />
NOTE: The proper Barometric Pressure or altitude MUST be entered<br />
to assure a proper calibration.
