Low Sensor- O2 or CO sensor outputs were low but still usable.
Sensor(s) may need to be replaced in the near future. Message will indi-
cate which sensor(s) were in warning.
Warmup Sensor Error -
• CO sensor was not zeroed at warmup 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.
• 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 tem-
perature range at startup.
• Pressure sensor is measuring pressure outside the range of ± 3 inwc
at startup. Ensure that the analyzer is sampling atmospheric pres-
sure and restart the instrument.
• The analyzer was turned on with the probe sampling flue gas. Move
the probe to fresh air and restart the instrument.
• Message will indicate which channel is in error.
Low Battery - Battery voltage is low. Replace the batteries.
XXXX - Occurs in the number fi elds of sensors that have achieved over-
range condition.
**** - Occurs in the number fi elds of sensors and the calculated values
that depend on the sensors that were in error coming out or warmup.
- - - - Occurs in the number fields of calculated values when Oxygen is
above 16.0%.
6.9 Diagnostics Screen
The DIAGNOSTICS menu provides information regarding the operation of
