OP – have you checked that CO reading?
I reset the meter and its reading 23 a day later. I may buy another as a comparison, its a Kidde one I currently have. Instructions seem to suggest below 30 is ok?
“Although the peak level feature will display levels below 30 PPM,
these levels will not result in an alarm no matter how long the
device is exposed to these levels.
The peak level feature is helpful in identifying CO occurrences
below 30 PPM. Although the unit will not automatically display
levels below 30 PPM, it will detect and store these readings in
memory. By pressing the peak level button, concentration levels
as low as 11 and up to 999 PPM will be displayed.
Concentrations of CO between 0 and 30 PPM can often occur in
normal, everyday conditions. Concentrations of CObelow 30 PPM may
be an indication of a transient condition that may appear today and
never reappear. Just a few examples of conditions and/or sources
that may cause readings blow 30 PPM are heavy automobile traf-
c, starting a vehicle in an attached garage, an appliance that
emits CO when starting up, a re in a replace or charcoal in a nearby
barbecue. A temperature inversion can trap CO generated by trac
and other fuel burning appliances causing readings of CO.”
