Procedure to Reset the Sensor
•
The incorrect reset of the sensor will result in incorrect Reading of the measured values.
To ensure high accuracy in the values measured by IRMA sensors, the following resetting recommendations should be followed.
Resetting must be performed by connecting an airway adapter to IRMA sensor, without connecting them to the breathing circuit. When
the gas monitoring signals have stable values, press the button to start resetting.
Special care must be taken to avoid any breathe near the sensor before or during resetting. The presence of ambient air (21% O2 and
0% CO2) in the airway adapter is of extreme importance for a successful resetting. If the error message
“Recalibration required”
appears immediately after the end of the resetting, this procedure must be repeated.
Resetting must be performed every time the airway adapter is replaced. It should be also performed whenever there is a shift of the
baseline (off
set) in any of the gas measures or when the error message “Accuracy of gas measures not determined” appears on the
screen.
After turning on the sensor or replacing the airway adapter, wait at least one minute before starting the resetting procedure in order to
allow heating of IRMA sensor. The green LED on the sensor will flash for 5 seconds while resetting process is in progress.
