The CO Protect feature protects the CO sensor from
the negative effects of being overloaded with CO gas.
Such negative effects include:
• a longer sensor recovery time
• a shortened sensor life.
The CO sensor is an electro-chemical sensor whose
lifespan is a function of its exposure to the target gas
(CO in this case). Though the CO sensor is designed to
be used in combustion environments having a fairly
wide range of CO gas present, limiting unnecessary
overexposure to CO gas can greatly increase the life
expectancy of the CO sensor. In addition, it can
shorten sensor recovery time after exposure.
The Protect CO feature sets a protection threshold
above which the analyzer’s pump shuts off, limiting the
CO sensor’s exposure to the high levels of CO gas and
its negative effects. Enter the Protect CO screen from
the Setup Menu. Select the “ON” option and press the
ENTER key. The CO threshold limit is displayed. Use
the up and down arrows to modify the CO limit
