Alarms:
Description: Displays all currently active alarms on the instrument. Equivalent to issuing
the status health command except that it only returns those portions of the status tree that have
active alarms. The advantage of this command over the alarm command is that it provides
additional data about the last time the alarm occurred and the number of times it has occurred.
However, some failure mechanisms can cause multiple alarms to be triggered and this command
can therefore produce extremely verbose output that makes it difficult to determine exactly which
alarm is the most important one and likely caused the other alarm conditions.

Clear Alarms:
Description: Clear all instrument alarms. The current alarm condition of the instrument
can be retrieved by typing status alarm at the command prompt. The returned alarm
information provides the most significant alarm condition that is currently active. It does
not necessarily indicate all alarm conditions currently present. For that purpose, health
nodes are used to monitor the current state of the instrument and raise alarms when the
specified condition is detected. The health nodes themselves are part of the status tree and
can be viewed by typing status health at the command prompt.
Once a health node is triggered it will produce one of two types of alarms:
Event alarm: Used to indicate alarms that have occurred but do not have a

persistent state. These alarms are latched and will remain active until the user
clears them with the clear_alarms command. Such an alarm might be triggered by
the loss of an external reference because even though the unit may switch to its
internal reference and continue to operate, the event is significant and warrants the
attention of the user.
