CALIBRATION-CHECK
Due to the ultrasound-based technology for airflow analysis, routine calibration of the
Spirohome
®
Clinic is not necessary and technically there is no mechanism provided to the
user to calibrate the device. The device is factory calibrated and a re-calibration can only be
done by the manufacturer. However, it is advised by the American Thoracic Society (ATS)
and European Respiratory Society (ERS) that periodic calibration-checks of spirometers are
performed.
4.1.1.
Preparation of Calibration Check
1. To check the calibration of the Spirohome
®
Clinic, a standard 3L calibration syringe
and a Spiroway Calibration-Check Adaptor must be used in the following
calibration-check procedures.
2. Ensure that the temperature inside the syringe and the room are the same. This is
necessary to prevent failed calibration-check due to temperature differences. You
can push and draw the piston of the 3 L calibration syringe a few times to balance the
temperature inside and outside the piston.
NOTE:
Avoid placing the body of the syringe near heat sources, or warming its casing with
hands.
3. Connect the device to the syringe as shown in the diagram.
4. To perform the Calibration-Check, select Calibration-Check in the settings section of
the Spirohome
®
app.
5. Then choose the Calibration-Check type as Multi-Flow Calibration Check or Linearity
Calibration Check and follow the instructions from Spirohome
®
App.
If any problem with the calibration of the device is detected, contact the manufacturer
immediately and do not perform any further tests with the device.
