MSA
The response levels for the individual gases are set at the factory and cannot be
changed during operation. After commissioning the instrument, changes are
possible only with the MSA FiveStar
(available as option; " Description of software).
If the ambient air contains higher gas concentrations, the instrument
ignores the Fresh Air Setup and goes directly to measuring mode after
the self-test.
