set high nox coef value
set low no coef value
set low no2 coef value
set low nox coef value
These commands set the NO, NO
values to value, where value is a floating-point representation of the
coefficient. The example below sets the NO coefficient to 1.005.
Send:
set no coef 1.005
Receive:
set no coef 1.005 ok
no gas
no2 gas
nox gas
high no gas
high no2 gas
high nox gas
low no gas
low no2 gas
low nox gas
These commands report NO, NO
to auto-calibrate low NO, NO
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 below reports that the NO low span gas concentration is 240.0
ppb.
Send:
low no gas
Receive:
low no gas 2400E-1 ppb
set no gas value
set no2 gas value
set nox gas value
set high no gas value
set high no2 gas value
set high nox gas value
set low no gas value
set low no2 gas value
set low nox coef value
These commands set the NO, NO
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 below sets the
NO span gas concentration to 123.4 ppb.
Send:
set no gas 123.4
Receive:
set no gas 123.4 ok
