PNEUMATIC OPERATION 

An  internal vacuum pump,  which is located pneumatically downstream from  all  the 

instrument’s other components, pulls the sample gas through the instrument’s pneumatic 

systems while keeping the analyzer’s sample gas inlet near ambient pressure by means of 

a small vent installed in the sample line at the inlet. The flow rate is controlled by a flow 

restrictor placed upstream of the sensor.  
After being pulled through a series of filtering and conditioning components, the sample 

gas is routed through the sensor for a true NO

2

  reading;  the sample gas is alternately 

titrated  with high amounts of ozone where  the sensor reads  a second, higher  NO

2

 

concentration, after which the two readings are used in calculations to provide a NO

X

 

value and an NO concentration.  
The alternating valve toggling for ozone titration is very rapid and follows a pattern of 

signal processing states that the Dashboard displays in the “SigProc State” parameter as 

described in Table 6-1.  To ensure accuracy, the analyzer periodically goes into AREF 

mode to run a background measurement while in Sample mode and  adjusts for any 

baseline drift that may occur.

NO2_WAIT 

Momentarily waiting for ozone to clear before sampling for NO

NOx_WAIT 

Ozone toggled on before sampling for NO

X

 gas. 

NOx_SAMPLE  Reading NO

2

 concentration in titrated sample (which will then be calculated 

for NO and NO

X

 readings). 

AUTOREF 

In Auto Reference mode. 

 
Briefly summarized, the  Model N500 analyzer  first  measures NO

2

  directly  by way of 

optical absorption to yield a true reading of NO

2

 concentration. Next, it uses a precisely-

timed pulsation to mix the sample with an excessive concentration of O

3

 to create NO

X

. 

The software subtracts the NO

2

 concentration from the resulting NO

X

 concentration to 

calculate an NO reading. The NO concentration is then corrected for titration efficiency 

(TE) and added into the NO

2

 value to produce a corrected NO

X

 measurement. 

Pressure transducers monitor the sample pressure and the cell pressure to verify pressure 

levels, which are used for a variety of important calculations and diagnostics.
