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".
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".
"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, ...
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 !
