The alarms menu displays a list of items that are monitored by the analyzer.
If the item being monitored goes outside the lower or upper limit, the
status of that item will go from "OK" to either "LOW" or "HIGH",
respectively. If the alarm is not a level alarm, the status will go from "OK"
to "FAIL". The number of alarms detected is displayed to indicate how
many alarms have occurred. If no alarms are detected, the number zero is
displayed.
To see the actual reading of an item and its minimum and maximum
limits, move the cursor to the item and press
The motherboard status, interface board status, and I/O Expansion board
status (if installed) indicate that the power supplies are working and
connections are successful. There are no setting screens for these alarms.
In the Main Menu, choose Alarms.

The Internal Temperature screen displays the current internal temperature
and sets the minimum and maximum alarm limits. The internal
temperature in the Model 48i Trace Level-Enhanced is regulated by
turning the fan on as the temperature gets too high and off as it gets too
low. Acceptable alarm limits range from 38 to 43 °C. If the internal
temperature reading goes beyond either the minimum or maximum alarm
limit, an alarm is activated. The word "ALARM" appears in the Run screen
and in the Main Menu.
