1.2.1
Configurations
The unit behavior is driven by configurations that are associated with events and
measurements, as well as miscellaneous features such as serial ports, system operation,
and various other system entities. The configuration utility provides customization of all
the configurable parameters. A complete list is provided in the Configurations Tab section
in this manual.
1.2.2
Events
Events are data entities that are associated with sensors and have a fixed number of
states. For example, external power can be off or on, or a measurement can be above or
below its alarm limit. When an event changes state, there are two actions that may take
place depending on the configuration for that event:
1.2.2.1
Log to the Event Log
The prior and current states are recorded along with date/time and optional comments
concerning the event.
1.2.2.2
Notification
The unit can be configured to send the event state when the state changes. The actual
output is an XML event command containing the same properties that are logged. See the
Notifications section of this manual for further details.
1.2.3
Scalar Measurements
Actual data values are represented by measurements. Most measurements fall into the
category of Scalar Measurements. A scalar is expressed as a numerical value. Each
measurement has a unit type, such as volts or dose rate, and formatting information
defined by its associated configuration. See the Software Configuration Utility section of
this manual for complete descriptions.
1.2.4
Composite Measurements
There are some measurements whose data does not fit into a numerical quantity.
Currently there are two measurements in this category, the battery charger data and the
optional meteorological sensor. In these cases, a block of data is provided by the device.
There are scalar measurements which are derived from the composite data. For example,
the scalar measurement BatteryCurrent is taken from the composite measurement. A
consequence of deriving scalars from the composite is that the sampling interval of
battery current cannot be independently configured, since it is tied to the update interval.
In this example, to change the Battery Current’s UpdateIntervalSpan the composite
measurement Battery Status has to be changed and not the scalar measurement’s
UpdateIntervalSpan. The table below shows which scalar measurements role up to which
composite measurements. When changing the UpdateIntervalSpan for the parent
composite measurement subsequently all child scalar measurements also change.
