-
The calibration gas does not reach the
Instrument correctly.
-
The concentration of the calibration gas has
not been defined in the Applied gas" line.
-
The user didn’t allow for the stabilization time
to properly elapse.
-
The sensor may be damaged or at the end of
its life and so must be replaced
It is always possible to return the Instrument to the original calibration with the "Status" line set to
"not active".
