Send: resp coef
Receive: resp coef 1.000
set resp coef value
This command sets the O
3
response 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
response coefficient to 1.500.
Send: set resp coef 1.500
Receive: set resp coef 1.500 ok
set o3 conc
This command sets the O
3
concentation to a user defined value. The
following example sets the O
3
concentation to 500 ppb.
Send: set o3 conc 5oo
Receive: set o3 conc 5oo ok
o3 setting
This command reports what the O
3
concentation the calibrator is set to
output. The following example reports that the calibrator is set to output
500 ppb.
Send: o3 setting
Receive: o3 setting 0500
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
