adapter is of crucial importance for a successful zeroing. If a “ZERO-REQ” alarm should appear
directly after a zeroing procedure, the procedure has to be repeated.
Always perform a pre-use check after zeroing the probe.
Zeroing for IRMA CO

probes:
Zeroing needs to be performed ONLY when an offset in gas values is observed, or when an
unspecified accuracy message is displayed.
Allow 10 seconds for warm up of the IRMA CO

probe after power on and after changing the
IRMA airway adapter before proceeding with the Zeroing Procedure. The green LED on the
probe will be blinking for approximately 5 seconds while zeroing is in progress.
Zeroing for IRMA AX+ probes:
Zeroing should be performed every time the IRMA airway adapter is replaced, or whenever an
offset in gas values or an unspecified gas accuracy message is displayed.
Allow 30 seconds for warm up of the IRMA AX+ probes after power on and after changing the
IRMA airway adapter before proceeding with the Zeroing Procedure. The green LED on the
probe will be blinking for approximately 5 seconds while zeroing is in progress.
18.3.2.4 Cleaning
The IRMA probe can be cleaned using a cloth moistened with maximum 70% ethanol or
maximum 70% isopropyl alcohol.
Remove the disposable IRMA airway adapter prior to cleaning the IRMA probe.
CAUTION
1
The IRMA oxygen sensor cell and IRMA airway adapters are non-sterile devices. Do
not autoclave the devices as this will damage them.
2
Never sterilize or immerse the IRMA probe in liquid.
18.3.2.5 MAC Calculation
The MAC value may be calculated and displayed by using end-tidal (ET) gas concentrations
according to the following formula:
MAC=%ET(AA
