an appropriate scaling factor to the analyzer‟s NO, NO
calculations so that the measurement range and concentration values shown on the
instrument‟s front panel display and reported via the instruments various outputs reflect
the undiluted values.
Using the Dilution Ratio option is a 4-step process:
1. Select the appropriate units of measure (see Section 5.4.3.4).
2. Select the reporting range mode and set the reporting range upper limit (see
Section 5.4.2).

Ensure that the upper span limit entered for the reporting range is the maximum
expected concentration of the UNDILUTED gas.
3. Set the dilution factor as a gain (e.g., a value of 20 means 20 parts diluent and 1
part of sample gas):

4. Calibrate the analyzer.

Ensure that the calibration span gas is either supplied through the same dilution
system as the sample gas or has an appropriately lower actual concentration.
EXAMPLE: If the reporting range limit is set for 100 ppm and the dilution ratio of
the sample gas is 20 gain, either:

a span gas with the concentration of 100 ppm can be used if the span gas
passes through the same dilution steps as the sample gas, or;

a 5 ppm span gas must be used if the span gas IS NOT routed through the
dilution system.
