Receive: co bkg 1.4 ppm
set co bkg value
This command is used to set the CO background to a user-defined value,
where value is a floating-point representation of the background in the
currently selected units. The following example sets the CO background to
1.4 ppm.

Receive: set co bkg 1.400 ok
bkg o2
This command reports the oxygen background concentration in percent.
The following example reports that the current O
concentration is 1.5%.
Send: bkg o2
Receive: bkg o2 1.50 %
set bkg o2
This command is used to set the oxygen background concentration in
percent. The example below sets the O
1.5%.
Send: set bkg o2 1.5
Receive: set bkg o2 1.5 ok
init ratio
This command reports the initial sample/reference ratio. The following
example reports that the initial ratio was 1.16210.
Send: initial ratio
Receive: initial ratio 1.16210
sp conc
high sp conc
low sp conc
These commands report span concentration in single range mode, or the
high and low span concentrations in dual or auto range mode. If the mode
is incorrect, the instrument responds with "can't, wrong settings". The
