There are eight standard displays on the CO80, although several of the
displays have multiple functions and options. These depend upon the
probes connected and menu selected.
Display 1
CO in ppm, carbon dioxide in
%, and ratio of the 2 gases –
use this screen to provide an
instant "health check" of the
boiler.
Display 2
Oxygen, excess air and
combustion efficiency all
in % - use this screen to
display how efficiently the
boiler is working.
Display 3
Displays oxygen in %, and
carbon monoxide in ppm – use
this screen to identify any CO
gas leaks and concentration
levels.
Display 4
Displays the positive and negative
pressure (selected by connecting to
the appropriate inlet).
Display 4 options also include a
tightness test count-up timer and
logging of the temperature during
pressure test, dependent on mode
and connections (see Section 5).
