2 Intended Audience This manual is intended for the person who uses, maintains, or troubleshoots this equipment.
3 Introduction The EasyOne-CS Spirometer uses digital ultrasonic flow measurement technology for fast, accurate, reliable operation. The EasyOne-CS was designed for full range testing in primary care, specialty physician, industrial and hospital settings. It offers automated comparison to predicted values, preand post Broncho Dilator comparisons, interpretation of results and test quality control that automatically assesses patient effort offering helpful suggestions to obtain optimum results. Optional easy to read and interpret color printout with graphic display for instant test review is available. The single-patient-use spirette minimizes risk of cross-infection.
4 Operation Principle This EasyOne-CS flow sensor is equipped with two ultrasonic transducers, mounted at different sides of the flow channel. In order to determine gas flow (and molar mass), ultrasonic pulses are transmitted in up- and downstream direction. Precisely measured transit-times are the basis for determining flow and molar mass. The following figure shows a diagram of the flow sensor including its internal sound transmission path.

8 Checkout Procedure After repair or maintenance of the EasyOne-CS the following procedure is recommended in order to check correct operations of EasyOne-CS:
Optional step: If all data in EasyOne-CS must be deleted, perform the ‘hidden key’ sequence 12-5 described in the following chapter in order to perform a factory reset. Please be aware that this step clears all customer data and resets the device to factory default settings. Get a calibration adapter and a calibration syringe (2030431-010) Ensure that the correct syringe volume is entered in the instrument’s configuration setting. Choose item “Check calibration” in the main menu of EasyOne.
2030434-006 Rev. D
EasyOne-CS Field Service Manual
Page 13
Connect the spirometer as shown below using the calibration adapter and the syringe. Ensure that the piston is fully inserted and at the stop position.
Now press ENTER. Wait until the baseline has been set and you hear an audible signal. Now execute one full inspiratory pump stroke followed by one full expiratory pump stroke at moderate speed. After you perform the maneuver, you will see the text "Accuracy confirmed" at the top of the display and, beneath it, the percentage deviation and the average flow velocity of the pump stroke. If desired, make a printout of the calibration report.
9 Hidden Keys The “hidden key” sequences access special features that are not available in the standard menu structure of EasyOne-CS. The following table shows what key sequences are available. The column labeled ‘Location’ indicates in what menu / screen the described key sequence has to be used. Caution: The key sequences should not be used in conjunction with patient testing. Location
