Potential Error Messages
1. O
2
SENSOR MISSING - The O
2
sensor is not installed.
2. T-STK DISCONNECTED - The probe thermocouple is not connected to the analyzer’s T-Stack
connector. Plug the probe thermocouple plug into the T-Stack connector at the bottom of the
instrument.
3. BAD SENSOR - O
2
sensor is too low and can not be calibrated in the instrument and needs
replaced.
4. LOW SENSORS - O
2
or CO sensor outputs were low but still usable. Sensor(s) may need to be
replaced in the near future. Message will indicate which sensor(s) were in warning.
5. WARMUP SENSOR ERROR - CO sensor was not zeroed at warm-up because of high output.
Run instrument on fresh air then restart instrument to re-zero sensor. If message persists CO
sensor may need to be replaced.
a. Stack or Air temperature channel is measuring temperature outside the range of -4 to 212˚F
at startup. Make sure that the Stack and Air thermocouples are sampling ambient room
air within the temperature range at startup.
b. Pressure sensor is measuring pressure outside the range of ± 3 in wc at startup. Ensure
that the analyzer is sampling atmospheric pressure and restart the instrument.
c. The analyzer was turned on with the probe sampling flue gas. Move the probe to fresh air
and restart the instrument.
d. Message will indicate which channel is in error.
6. LOW BATTERY - Battery voltage is low. Replace the batteries.
7. XXXX - Occurs in the number fields of sensors that are in over-range.
8. **** Occurs in the number fields of sensors and the calculated values that depend on the
sensors that were in error coming out or warm-up.
9. **** Occurs in the number fields of calculated values when Oxygen is above 16%.
