Choose signal source module…
Select the “Analyzer Modules” submenu
by selecting the “Choose signal source
module…” line and pressing the
↵
soft-
key.
Select the tag of the desired reference
channel with the
↑

↓
softkeys and then
press the
↵
or
→
softkey. The display will
return to the previous menu automatically
and the selected reference channel will be
displayed in the “Source module:” line.
The available selections may be different
depending on the installed modules.

Choose signal…
Select the “Signals” submenu by selecting
the “Choose signal…” line and pressing
the
↵
softkey. (The list of signals will de-
pend on the module chosen.)
Press the F5 softkey to go to additional
menus to choose the Primary Variable
signal for the analog output. The Primary
Variable is the actual NO or NOx concen-
tration.
The signal chosen here will be applied to
the analog output (1-8) chosen above.
See Section 3-7b, page 3-13 for a list of
the signals and their values.
Figure 3-43. Signals Menu
Signal value for 0% (100%) output:
It is possible to set the signal value for 0%
output and for 100% output so as to out-
put only a portion of the entire range.
Example:
Range from 0 to 1000 ppm
0% value to be 400 ppm, 100%
value to be 700 ppm.
Analog output normally: 0V = 0
ppm, 10v = 1000 ppm
After changing the output scaling:
0V = 400 ppm, 10V = 700 ppm
Move the cursor to the “Signal value for
0% output:” line and adjust the value to
400. Then change to the “Signal value for
100% output:” line and adjust the value to
700.
NOTE
If the measurement range is changed,
the settings done in this menu will re-
vert back to the standard values of the
range. The output values can be
changed permanently in the menu
“Range Settings.” See Section 3-7a,
page 3-12.
