set o3 coef value
set high o3 coef value
set low o3 coef value
These commands set the O
3
coefficient to user-defined values to value ,
where value is a floating-point representation of the coefficient. The
example that follows sets the O
3
coefficient to 1.005.
Send: set o3 coef 1.005
Receive: set o3 coef 1.005 ok
o3 gas
high o3 gas
low o3 gas
These commands report the low O
3
span gas concentrations used to
auto-calibrate low O
3
coefficients. 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 example that follows
shows that the O
3
low span gas concentration is 240.0 ppm.
Send: low o3 gas
Receive: low o3 gas 2400E-1 ppm
set o3 gas value
set high o3 gas
value
set low o3 gas value
These commands set the O
3
span gas concentrations used by the
auto-calibration routine to
value
, where
value
is a floating-point
representation of the gas concentration in current selected units. The gas
units are the same as those chosen by the user. The example that follows sets
the O
3
span gas concentration to 123.4 ppm.
Send: set o3 gas 123.4
Receive: set o3 gas 123.4 ok
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.
