Introduction
The SP-2 Hand-Held Spirometry Unit features three
pulmonary function testing modes for the
measurement of inspiratory and expiratory values.
The large LCD screen instantly show pulmonary
test results and provides a clear and comprehensive
result analysis in a number of different formats. All
tests and settings are initiated via an easy to use
interface.
The sensor mouthpiece is a disposable, single
patient sensor/filter assembly eliminating the need
to clean the sensor after each use.
All functions and settings are selected via menus
displayed on the LCD with direct test function
menu options for measuring the following:
nFVC Forced Vital Capacity
nSVC Slow Vital Capacity
nMVV Maximum Voluntary Ventilation
(Option)
1. Battery Compartment
Two, 1.5V non rechargeable AA batteries
2. 12 Alpha numeric keys
For text / numerical input e.g. patient data, calibration data etc.
3. Three Direct Function keys:
Print / Send. This key initiates transmission over the infrared interface
to a compatible printer using the standard data association protocol.
LCD Backlight Key - The middle key is the ON/OFF control for the
LCD backlight. The backlight is automatically switched off after
approximately 10 seconds.
The START/STOP (and ON/OFF) key has three functions:
nSwitches the unit on.
nWhen the unit is switched on and in test mode, this key starts /
stops a measurement.
nWhen the unit is switched on and not in test mode, this key
switches the unit off (press for 2-3 seconds).
4. Four (menu navigation/selection) Function keys:
LEFT / RIGHT keys - The functions of these keys depends on the
menu displayed and is shown in the bottom line of the LCD line. In
general however, the left softkey selects the functions and the right key
acts in a similar way to the 'enter' key in a PC. See following pages.
The UP and DOWN keys move the cursor in the menu fields to
highlight the menu options. These two keys can also act as extra
function keys - in this case the function is shown in the bottom line of
the LCD line.
