Pc Connection; Calibration - CareFusion MicroCO Meter Manuel D'utilisation

Note: If this warning appears again after following the above
procedure then turn off and leave the sensor exposed to ambient air
for a further 3 minutes. If the same message appears again then this
indicates possible contamination of the sensor with a solvent.
In this case remove all sources of solvent from the vicinity of the
sensor and expose to ambient air for 24 hours before switching on
again.

PC Connection

The MicroCO may be connected to the serial port of a PC running
COBRA (CO BReath Analysis) software.
This software allows the measurements to be read by a PC and
automatically entered onto a pre-defined report for subsequent
printing and filing. It also allows the CO level indicators and the breath
holding countdown timer to be configured to individual requirements.
Note: The MicroCO should only be connected to a computer that is
manufactured in accordance with EN 60601-1.
Note: Keep the PC out of reach of the patient at all times.

Calibration

Calibration will remain stable to within 2% over one month and
typically to within 10% over 6 months. CareFusion supplies calibration
gas (20ppm CO in air) and recommends that the unit is recalibrated on
a 6 monthly basis. See page 71 for calibration accessories.
The gas is supplied in convenient, disposable, aluminum aerosol cans
containing 20 liters of gas (Cat. No.36-MCG020).
