4.3 The sensor's zero
1). Zero
The vapour-prevent window of the airway adapter has a certain attenuation to
infrared signal but due to individual diversity, its attenuation is different. So the
sensor needs to be zeroed when changing new adapter. In addition, the sensor and
in fared source have a certain of drifting, the sensor need to be zeroed after long
usage, if the data is not correct, sensor also needs zero.
Attention: Zero needs to be careful, otherwise the false zero calibration will cause
deviation of measurement data. 2). Zero method:
Connect the probe with host and warm up 5-10 minutes. Input the device into
space without CO2 and attention, do not breathe near it. Then, enter CO2 setting
submenu, move cursor to’ZERO’, if this item is high-luminance colour, that means
the sensor's data is stable and can make zero. Then press
+/
button, send zero
order and ‘ZEROING’ will be shown and wait for 15-20 seconds till ‘ZEROING’
disappears.
4.4 Notice
Caution
: Under the conditions of electromagnetic influence, for example:
electrosurgical devices, MRI, CT etc. will cause negative impact.
Attention
: indicating other important information.
The readings of CO2 may be wrong if the monitor does not warm up.
Use the airway adapter only provided by the manufacturer otherwise, measurement
data might be not correct.
Measurement data might not be correct if under strenuous temperature changing
surrounding. Therefore, if short temperature change comes beyond a certain
range, ‘TEMP IMBALANCE’ will be shown on the screen, so should better use
under stable temperature surrounding. When patient is used with anaesthesia
gas, the measurement data will be a little bit influenced. If needs to calibrate on
anaesthesia gas, please refer to Appendix 2. Warning:
The power adapter with naked electric point must not be applied- Dangerous for
electric shock!
