Note 1
: Negligible interference, effect included in the specification “Accuracy, all conditions”
above.
Note 2
: For probes not measuring N
2
O and/or O
2
the concentrations shall be set from host
according to the instructions. (IRMA CO
2
measures neither N
2
O nor O
2
.)
Note 3
: Interference at indicated gas level. For example, 50 vol% Helium typically decreases the
CO
2
readings by 6%. This means that if measuring on a mixture containing 5.0 vol% CO
2
and 50
vol% Helium, the measured CO
2
concentration will typically be (1-0.06) * 5.0 vol% = 4.7 vol%

Note 4
: According to the EN ISO 80601-2-55:2011 standard.
Note 5
: In addition to the EN ISO 80601-2-55:2011 standard.
