Note Zero air must be provided to the instrument prior to issuing any of
these commands. ▲
Send: set cal co bkg
Receive: set cal co bkg ok
cal bkg o2
This command will set O
0.00%. The example below shows a successful auto-calibration of the O
background.
Send: set cal bkg o2
Receive: set cal bkg o2 ok
set cal co coef
set cal high co coef
set cal low co coef
set span calibrate
set calibrate
These commands will set CO coefficients based on CO span gas
concentrations. The high and low commands are only available in dual and
auto range mode. If the mode is incorrect, the instrument responds with
"can't, wrong settings". The following example shows a successful auto-
calibration of the low CO coefficient.
Note Span gas must be provided to the instrument prior to issuing any of
these commands. ▲

co coef
high co coef
low co coef
These commands report the current CO coefficient in single range mode,
or the high and low range coefficient in dual or auto range mode. If the
mode is incorrect, the instrument responds with "can't, wrong settings".
The following example reports that the CO coefficient is 1.200.
