Caution: When you miss the correct spots, the window will disappear. In
this case you have to restart the device and the calibration procedure.
Technical Inspections
For safety, the device requires regular maintenance. To ensure functional and
operational safety of the device, Technical Inspections should be carried out
on an annual basis.
These checks should be performed by persons with adequate training and
experience.
The inspections include the following checks:
Visually inspect the device and the accessories for signs of
mechanical damage that may impair the device functions.
Check that the device safety labelling is legible.
Run a functional test.
Check measuring accuracy (see following section).
Check Measuring Accuracy
Calibration Check with Syringe
Note
As an alternative, the calibration can be checked with a test
subject (see "Calibration Check with Test Subject" on
page 107).
The EasyOne Pro™ calibration can be checked with a syringe using the cali-
bration check function. The American Thoracic Society (ATS) recommends
that the spirometer calibration be checked on a regular basis. Owing to the
ultrasound technology used in the flow sensor, the device requires no cali-
bration, even if used frequently. To comply with the recommendations, you
can check the calibration as follows:
You need the ndd calibration adapter and a calibration syringe (order num-
ber 2030-2).
Using the calibration adapter, connect the sensor to the syringe as
shown below. Ensure that the piston is fully inserted and at the stop
position.
In the Utilities menu, click Calibration Check, then select Syringe
Calibration Check.
On the test screen, click Start.
Wait until the baseline has been set.
Now execute one full inspiratory pump stroke followed by one full
expiratory pump stroke at moderate speed.
