The Historical Alarm Mode is similar to the Active Alarm mode, but it provides an additional time 
range back from the present time to search for measurements in alarm condition or have been in 
alarm condition.  Again the most recently raised measurement alarms appear first, followed by 
corrected measurements.

Let’s drill down on the measurement in alarm state for more detailed analysis.  Click on the Zoom 
button for measurement “Mod-1400” to display the CarrierWatch Zoom window as shown in Figure 
25.

By default the “Live Update” mode is turned on, which shows you the latest trace in the bottom of 
the screen.
