commands report the coefficients of the curve developed from the Lo
Multi-Point Calibration in dual and auto range mode. The example below
reports the coefficient 0 having a value of 1.005.
Send: coef 0
Receive: coef 0 1.005 ok
co bkg
This command reports the current CO backgrounds. The example below
reports that the CO background is 1.4 ppm.
Send: co bkg
Receive: co bkg 21.4 ppm
set co bkg
value
This command is used to set CO backgrounds to user-defined values to
value , where value is a floating-point representation of the background in
current selected units. The example below sets the CO background to 1.4
ppm.
Send: set co bkg 1.400
Receive: set co bkg 1.400 ok
init ratio
This command reports the initial sample/reference ratio. The example
below 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
example below reports that 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
