NOx converter efficiency
↓↓
In this menu you can optimize NOx converter efficiency.
1) Set up the desired converter temperature (set point):
• 
Press the ENTER key or the 
 -key to select the parameter
• 
Select any digit you want to change with the 
 -key or the 
 -key and adjust a new
value with the 
↑↑
 -key or the 
↓↓
 -key.
• 
Let the temperature stabilize.
2) Apply a test gas:
• 
Apply a test gas and select NO or NO
x
 with the F3 key:
The component selected will appear in the line "Measurement mode".
3) Store the reading and the temperature:
• 
Press the F3 key (NO/NOx) again after the reading will be stabilized:
The current signal and the actual converter temperature will be stored automatically
and displayed in the line "Last measurement" resp. "Last temperature reading".
4) Optimize the temperature:
• 
Compare the stored values with the actual values in the lines "Measurement" and
"Converter temperature".
• 
Repeat the steps 1) to 3) to get the optimized converter temperature you want:
Change the converter set point as desired, let it stabilize, apply test gas, F3, ...
Note: The steps 2) to 4) will only be available using the CLD software revision 2.3 !
