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.

5.3 Block Diagram
The following picture shows the functional block diagram of the EasyOne-CS Spirometer.
5.4 Printed Circuit board
All electrical components of EasyOne-CS are mounted on a single PCB.
With the exception of the lithium battery no components can be serviced.
The following two pictures show a top and bottom view of the PCB.
Figure 7: Bottom view of EasyOne-CS PCB
The lithium battery located on the top right of the PCB has an approximate life time of 5 to 10 years. In
early revisions of the hardware the lithium battery is soldered on the board.
