Initial Start-Up; Dry Down Period - Ametek 5920 UHP User Manual

Initial Start-Up

1. Open the main sample shutoff valve at the source.
2. Turn on the AC power at the source. Boot-up information will appear on
3. Once sample flow starts, the analyzer will be in the normal operating

Dry Down Period

Sample must be flowing during the dry-down period. You should allow 5–7
days for the analyzer to dry down and stabilize. During this period, the concen-
tration 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.
The 5920 Moisture Analyzer is now fully operational with factory default con-
figuration of the analog output and Concentration alarms. You are ready to do
an initial Zero cycle.

If the concentration value is still decreasing after the initial dry down
period, allow additional dry down time.
