Operating Basics
Error indicator color codes.
The RFM220 Client uses colored LEDs to
indicate the status of signal measurements and device events. Use the Alarm
Con
fi
guration dialog box to enable/disable tests, and to categorize error levels
and set measurement limits for each test. (See page 60,
Table 7: Error indicator color codes
Item
Description
Red indicates that a test categorized as Critical has failed or that a threshold
limit on a Critical test has been crossed.
Amber indicates that a test categorized as a Warning has failed or that a
threshold limit on a Warning test has been crossed.
Blue indicates that a test categorized as Information has failed or that a
threshold limit on a Information test has been crossed.
Green indicates that a test has not failed or that a threshold limit has not
been crossed.
Gray indicates that a test is disabled.
Date and time displays.
When the Aggregator is started, it pushes the UTC
time into each instrument listed in the Con
fi
guration.xml
fi
le. All of the times
that are shown in the RFM220 Client displays (for example, in the event log
entries and in the Status bar), are the times reported by the RFM220 instrument
in terms of the time on the RFM220 Client computer, including taking into
account the local time zone and daylight savings time settings.
Changes to the time zone or daylight savings time settings that occur on the
RFM220 Client computer after the RFM220 Client has been started, will be
automatically accounted for in the time displays on the RFM220 Client.
NOTE.
There may be a small discrepency in the time displayed on the RFM220
Client computer and the time displayed in the RFM220 Client. This is caused
by small time drifts in the RFM220 instrument that occur after the instrument
receives the UTC time from the RFM220 Aggregator.
Online and of
fl
ine monitoring.
In the RFM220 Client Login dialog, the
monitored devices list includes a status column, which lists one of the
following as the status of the monitored device: (See Figure 22 on page 39.)

available to the Aggregator.
Of
fl
ine. Indicates that the device is an RFM220 instrument and that it is
turned off or otherwise unavailable to the Aggregator.
NOTE.
Since trend data and log entries are stored by the RFM220 Aggregator
for as long as it remains running, you can still connect to an of
fl
ine
RFM220 instrument if that instrument was ever monitored by the Aggregator.
In this case, you will be able to view trend data and event log entries for the
of
fl
ine device that was collected in the past while the device was online and
being monitored by the Aggregator.
