1.
Open the main sample shutoff valve at the source.
2.
Adjust the sample pressure (6 to 50 PSIG).
Maximum inlet pressure is 50 PSIG. Damage can occur if higher
!
pressures are introduced to the analyzer.
CAUTION
3.
Turn on the AC power at the source. Boot-up information will appear
on the display followed by the operation screen (Figure 3-14).
4.
Once sample flow starts, the analyzer will be in the normal operating
mode. Lines 3 and 4 will flash various messages and alarm conditions
at start-up.
5.
Allow the analyzer to warm up for a minimum of 45 minutes.
Dry-down period
Sample must be flowing during the dry-down period. You should allow 5
to 7 days for the analyzer to dry down and stabilize. During this period,
the concentration value shown on the display and the data recorded from
output should show a steadily decreasing trend. System alarm messages
may be displayed during this period.
When the dry down is complete, the concentration value on the display
should be stable and the recorded data should have leveled off. Zero
alarms will still be on the display.
If the concentration value is still decreasing after the initial dry down
period, allow additional dry down time.
NOTE
The 3050-AMS Moisture Analyzer is now fully operational with factory
default configuration of the analog output and concentration alarms. You
are ready to do an initial zero cycle.
