Procedure for speeding up the dry down period
To decrease the time required to dry down the 3050 AM analyzer, follow
this procedure:
1. Make all gas connections and apply power to the analyzer. Allow the
analyzer to warm up and run with the factory-default settings for a
period of 6 to 12 hours.
2. At the end of this interval, set as follows:
Zero Schedule Type to “Daily”
Zero Duration to 720 cycles (i.e., 12 hours)
Zero Hour to 1
The exact menu location for each of these parameters can be found by
referring to the Menu Map at the beginning of Chapter 4.
Once you apply these settings, the analyzer will run a 12-hour zero
every day at 1 AM. The analyzer will spend 50% of the time on the
sample gas and 50% of the time on the internal zero. These settings
enable the analyzer to more effectively dry all of the surfaces within
the sample manifold.
3. After 3 to 4 days, the analyzer setup can be returned to normal opera-
tion (e.g., the factory default values).
Performing an Initial Zero
To start the initial zero cycle:
1. Press the Zero key.
2. Press the #8 key (arrow down) until you see “Zero” between the ar-
rows. Select “Zero” by pressing Enter .
This initial zero cycle takes approximately two hours. When the zero cycle
is complete, the analyzer will adjust the offset and automatically return to
normal sampling.
The 3050 AM analyzer requires time to fully recover to normal opera-
tion after zeroing. During the recovery period, “Equilibrating” will be
shown on line two of the display.
