Zero/check/calibrate CO2 sensor
● Connect the calibration gas supply.
Use the cuvette from the calibration
set!
1 Connect the calibration gas cylinder
and the cuvette of the calibration set
to the hose.
2 Remove the CO2 sensor from its
park bracket and fit it to the cuvette of
the calibration set.
3 Read the CO2 and O2 concentration
(if applicable) of the calibration gas
from the calibration gas cylinder.
Enter these concentration values with
the screen knobs.
● Touch the screen knob.
Enter the concentration
= turn rotary knob,
confirm = press rotary knob.
If the calibration gas comprises CO2, O2
and N2:
● Enter the O2 concentration read off.
If the calibration gas only comprises
CO2 und N2:
● Set the O2 concentration to »0«.
● Touch the screen key »Gas Check«.
EvitaXL displays the CO2 concentration
FCO2 in the menu.
Example: FCO2 5.0 Vol.%.
After about 10 seconds, the value of
FCO2 must match to within ±0.2 Vol.%
the CO2 content of the calibration gas.
If the calibration value is outside the permitted
tolerance, the CO2 sensor must
be recalibrated with test gas.
● Push CO2 sensor back on the
cuvette.
