5-22 | Model 900 ADA / Model 930 Sulfur Pit Analyzers
10. For the new lamp, view the Ftr screen to determine the filter location
with the highest lamp pulse current-control value.
The last digit in each of the following commands is the filter location.
Pressing Ent returns the CFG mode normal display.
If Lamp1 was replaced, display the values using these commands
(* see Note):
F1 1 1
F1 1 3
F1 1 5 Ent
If Lamp 2 was replaced, display the values using these commands
(* see Note):
F1 1 4
F1 1 6
F1 1 2 Ent
If the lamp pulse current-control value for a filter location is negative,
that filter location is not used.
* The filter positions assigned to each lamp will change depending
on the species being measured, the lamp types, and the application.
For the filter sequence for your application, view the Bench Type
Code (press F2 1 in RUN mode) and then refer to the Filter Position
Assignment descriptions (see “F2 1” under “RUN/CFG Mode – F2
Commands” in Chapter 4).
11. Turn off the Automatic Lamp Control (Alc). The Alc Enable function
must be off to ensure the analyzer does not make automatic adjust-
ments while you are setting the Measure and Reference signals to oper-
ate at optimum ratios to each other, in the following steps.
12. For the filter location with the highest lamp pulse current-control
value, view the SIG screen and display its PMT signal by pressing
F6 1z, where ‘z’ is the filter location.
The message “SIGz m.mmm r.rrr” is displayed, where ‘z’ is the filter
location, m.mmm is the Measure PMT signal, and r.rrr is the Reference
PMT signal. The PMT signal values are updated at one-second
intervals.
