Anyview A6 - 13.6 Calibration

Patient monitor User’s manual
Chapter 13-9
Caution:
 Always ensure that the sampling tube is properly connected to the
microstream CO
2
sensor before zeroing.
 Always ensure that the mainstream CO
2
sensor is properly connected to
the airway adapter before zeroing.
 Do not attempt zeroing for 20s after removing the adapter or cannula
from the patient’s airway. This time allows any CO
2
remaining in the
adapter or cannula to dissipate before zeroing.
 Do not attempt to zero the sensor while the adapter or cannula is in the
patient’s airway.
 Do not attempt zeroing if the temperature is not stable.
 Zeroing with CO
2
in the adapter or cannula can lead to inaccurate
measurements or other error conditions. If you attempt zeroing while
CO
2
remains in the adapter or cannula, the time required to zero the
sensor may be increased.
13.6 Calibration
The monitor has already been calibrated before leaving factory. User can
directly apply it to measuring in normal conditions, to the exclusion of the
below conditions.
For Sidestream CO
2
module, please carry out gain calibration and manual
offset calibration, when the following conditions happened: (More details
refer to Service Manual.
——The module has been used for between half a year and one year.
——The accuracy of CO
2
reading has been doubted by clinical physician.
——After the latest calibration, atmospheric pressure or height above sea
level varies evidently.
Caution: User may only calibrate the device under the instruction of
the technical personnel authorized by manufacturer.
Moreover, incorrect calibrating procedure may result in
incorrect reading.
