Then perform the calibration:
•
Perform a Zero calibration using zero air.
•
Perform a span calibration on both the NO & NOx channels using a known
concentration of NO span gas.
•
Perform the two-point Converter Efficiency (CEA and CEB) calibration using a
known concentration of NO
2
span gas.
Note
The span gas concentration should be 80% of range of
concentration values likely to be encountered in your
application.
To calibrate or to perform a calibration check for basic configuration instruments, see
Section 4.2.1.
To calibrate or to perform a calibration check for instruments with valve options, see
Section 4.2.2.
To perform a calibration check for instruments with the internal span gas generator, see
Section 4.3.

Although this section uses the Calibration menu for both check and actual calibration, a
check does not require the Calibration menu. Instead, while in Home page, simply flow the
zero air or the NO span gas through the Sample port, and check the reading after the
Stability falls below 1.0 PPB (either in the gas graph or in the Dashboard).
Otherwise, follow the steps presented in Sections 4.2.1.1 and 4.2.1.2.
