5.3.1 Probe replacement and viewLinc alarms
If the data logger is connected to a viewLinc Enterprise Server, probe replacements activate
the appropriate alarms in viewLinc.
Probe Changed alarms
These alarms are always activated to notify the administrator that a probe has been changed.
The alarm has to be acknowledged by the administrator.
RFL100 data logger communicates changed probe information automatically to viewLinc
Enterprise Server. This information includes the serial number and calibration information
stored in the probes. Stored data points are automatically associated with the correct probe.
Missing Historical Data alarms
These alarms are activated for Locations that are linked to channels of the data logger when
viewLinc notices that realtime data is not being received. The alarms will be cleared when the
data logger reconnects and viewLinc retrieves any data that was locally stored on the data
logger during the connection break.
If you need to avoid any interruption to monitoring, use the Swap Device feature of viewLinc
Enterprise Server to link another device to the monitored Location for the duration of probe
replacement. See viewLinc User Guide.
If you replace the probe with a dierent model that does not have
the same measurement channels (for example, replacing RH+T probe with a T-
only probe), unlink the channels from the old probe(s) in viewLinc Enterprise
Server before you start. Always unlink the channels before changing between
one and two probe operation.
