o3 bkg
These commands report the current O
3
background. The example that
follows reports that the O
3
background is 5.5 ppb.
Send: o3 bkg
Receive: o3 bkg 5.5 ppb
set o3 bkg value
These commands are used to set O
3
background to user-defined values to
value , where value is a floating-point representation of the background in
current selected units. The example that follows sets the O
3
background to
5.5 ppb.
Send: set no bkg 5.5
Receive: set no bkg 5.5 ok
set cal detectors
This command is used to balance the output for both detectors so that they
read the same value
Send: set cal detectors
Receive: set cal detectors ok
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
example below reports the span gas concentration in single range mode.
Send: sp conc
Receive: sp conc 1000
set sp conc
value
set high sp conc value
set low sp conc value
These commands set the span concentrations to user-defined values to
value , where value is a floating-point representation of the span
concentration in current selected units. The example below sets the span
concentration to 1000 ppb in the single range mode.
