EvitaXL

● Place the test filter in the
CO2 sensor.
EvitaXL displays the test value of the
CO2 concentration FCO2 in the menu,
example:
FCO2 4.0 Vol.%
This value must agree to within
±0.3 Vol.% with the specification on the
test filter.
Example: 4.1 Vol.% on the filter:
permitted value range: 3.8 to 4.4 Vol.%
If the test value is outside the permitted
tolerance, the test gas must be checked
or calibrated.
● Push CO2 sensor back on the
cuvette.
Checking CO2 calibration with calibration
gas
— if the specified calibration value
was not met when testing with the
test filter
— at least once per half-year.
Calibration gas containing N2O must
not be used!
● Switch on EvitaXL and wait at least
3 minutes for the CO2 sensor to complete
its warm-up phase.
● First perform CO2 zero calibration,
page 111, then:
in the menu »CO2«:
● Touch the screen key »Check
sensor«.
