HIGH CAL/CHK
OUTSIDE TOL
or
LOW CAL/CHK
OUTSIDE TOL
User set low or high
calibration tolerance
has been exceeded
during auto calibration
Check that calibration
gas is not empty.
Increase tolerance if
necessary.
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.
HI CAL/CHK
OUTSIDE RANGE
or
LO CAL/CHK
OUTSIDE RANGE
The gas concentration
specified in the
autocalibration
configuration is outside
of acceptable limits.
Respecify the
calibration gas
concentration.
HI CAL RESULT
OUTSIDE LIMITS
or
LO CAL RESULT
OUTSIDE 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.
Table 8.2 shows a list of the diagnostic signals available for the paramagnetic
transducer.
