STEP 3 – Set NO
x
and NO span gas concentrations :
Set the expected NO and NOx span gas concentration. These should be 80% of range of
concentration values likely to be encountered in this application. The default factory
setting is 100 ppm. If one of the configurable analog outputs is to be set to transmit
concentration values, use 80% of the reporting range set for that output (see Section
4.13.4)
If you supply NO span gas to the analyzer as well as NO
x
, the values for expected NO
and NO
x
span gas concentrations need to be identical.

80.0 Conc.
If this is not the the concentration of
the span gas being used, toggle
these buttons to set the correct
concentration of the NO

calibration gases.
EXIT ignores the new
setting and returns to
the previous display.
ENTR accepts the new
setting and returns to
the

If using NO span gas
in addition to NO

repeat last step.
