Troubleshooting
Message
Status level
Description Recommended Actions
Flow Low-Low
Failure
The detected ow is too low
or missing due to a leak, not
limited to the instrument‘s
internal gas path
• Check the external and inter-
nal gas path for leakage and
plugging
• If applicable check internal
pump function
Invalid Interference Value
Off-spec
A measuring value used for
cross interference compensa-
tion is found to be erroneous.
Check status of interfering
components
Linearizer Overow
Off-spec
The current concentration va-
lue is above the upper lineari-
zation range limit, so measu-
ring results are not reliable.
Adjust gas concentration to be
within range
Linearizer Underow
Off-spec
The current concentration
value is below the lower linea-
rization range limit, so measu-
ring results are not reliable.
Adjust gas concentration to be
within range
Operation Hours Exceeded
Maintenance
The operation hours excee-
ded the service interval time.
• The instrument, or selected
components require mainte-
nance
• After maintenance, enter SE-
TUP - OPERATION HOURS
METER ( 6-97 ), to reset
the counter.
No Sample Gas
Function check
The concentration measure-
ment does not represent the
normal value. Possible rea-
sons: Calibration procedure is
busy.
• Check, if a calibration is
ongoing
• If no calibration is ongoing,
check if sample gas is ap-
plied (if need be, check for
open sample gas valves)
Range Overow
Off-spec
Gas concentration is out of
measurement range and
therefore linearization curve
does not apply (measuring re-measuring re-
sults are not reliable).
• Select higher range (polyno-
mial linearization mode only)
• Adjust gas concentration to
be within range
