4.1.2 HIGH CO ALARM
Should the CO reading rise above 2,000ppm a continuous series of Alarm Beeps
will be heard. If this occurs then the Probe should immediately be disconnected
from the instrument and the instrument returned to a clean air environment. This
Alarm alerts the user that there is a high concentration of CO, and this procedure
will protect the sensors within the instrument.
Failure to comply may result in damage to the instrument and will invalidate
the warranty.
