set o3 coef value
set high o3 coef value
set low o3 coef value
These commands set the O
where value is a floating-point representation of the coefficient. The
example that follows sets the O
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
auto-calibrate low O coefficients. The high and low commands are only
3
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 low span gas concentration is 240.0 ppm.
3
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
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 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
follows reports that the O
Send: o3 bkg
Receive: o3 bkg 5.5 ppb
set o3 bkg value
These commands are used to set O
value, where value is a floating-point representation of the background in
current selected units. The example that follows sets the O
