A- SETUP & CALIBRATION MENU OVERVIEW
The following is an overview of the SETUP and CALIBRATION (CAL) menus. Some functions in these menus will be
used in the performance checks that follow this overview and will be further explained there.
To activate the SETUP and CALIBRATION menus, turn the ON/OFF switch to ON and press the SETUP key. This key
is only available immediately after power-on. It is replaced by the ARROW keys by either pressing any key, with the
exception of the ALARM QUIET or BATTERY key, or by timing out after 30 seconds with no key being pressed. When
pressing the SETUP key, the SETUP menu will appear and the alarm LED will turn on and remain on as long as this menu,
or any menu accessed from this menu, is displayed. It is possible to go to the CALIBRATION menu by pressing the CAL
MENU key or to return to normal operation at any time by pressing the MAIN MENU key.
1- SETUP MENU OVERVIEW
OXYGEN SENSOR CALIBRATION
This function is used to calibrate the Oxygen sensor cell.
NOTE: It is important to use the correct reference gases (100 and 21%) when performing this
calibration. A worn out sensor will not calibrate accurately.
NOTE: Due to the fact that O2 sensors sometimes change output over time once exposed to
atmosphere, a calibration should be performed once a month in order to assure optimal accuracy. When
the sensor is consumed and does not calibrate properly, it should be discarded and a new sensor
installed and calibrated.
LEAK TEST
Tests the integrity of the patient circuit and its connections.
INSP/TV
Allows the user to choose between Inspiratory Time and Tidal Volume as it is displayed in the menus. When INSP TIME is
pressed and the SETUP menu is exited, INSP (inspiratory) will be displayed below the RATE key in the MAIN menu,
thereby allowing the user to set an inspiratory time directly. If tidal volume would rather be set, then press TIDAL
VOLUME in the SETUP menu and exit. Whichever is chosen will remain in effect until it is changed in this menu.
LANGUAGES
Allows for the menus to be displayed in a different language.
VER (VERSION)
Indicates the software version installed.
SN (SERIAL NUMBER)
Indicates the serial number of this unit.
