LIMITS
The results of an
autocalibration are
different from the
existing values by more
than the specified
tolerance limits.
Check that calibration
gas is not empty.
Check that the
concentration of the
calibration sample
corresponds with the
concentration specified
in the autocalibration
configuration. Perform
an ONE CYCLE
autocalibration to clear
the fault. If a
successful calibration
can not be achieved
then call a service
engineer.
