4.3 Identification
LED, beeping and vibration may be switched to "off".
Data collection begins as soon as the unit is switched to Finder mode. Measurements are then collected by the FLIR
identiFINDER R200's sensors and processed by the on-board firmware.
A background measure should be thought of as a sort of "baseline" that measures the ambient radiation existing nor-
mally in an area.
"Background", is not, in essence a history, but rather a real-time building of history that is stored in the FLIR
identiFINDER R200data banks. Levels may differ with respect to location and based on a multitude of factors. Estab-
lishing this baseline, before actually seeking out a source, is crucial in that it establishes for the FLIR identiFINDER
R200 processors what exists "naturally" and then, over and above (when seeking a source) - what stands out as an
anomaly (in other words, what should not be there in the field view of naturally-occurring levels).
For best results when possible, move the FLIR identiFINDER R200 away from suspected radiation
sources during background data establishment. A source
contributes to that measurement and will thus skew the data set, likely establishing a backround read-
ing that is not consistent with true background conditions (that condition existing without the intro-
duction of a source that would not, otherwise, be there).
"Duration" (current count rate) is displayed below the chart and is expressed in terms of time transpired (passed) and
overall length of measure (how much time the unit is set to collect background data).
After the background measurement is complete, the "Finder"mode is displayed.
4.3 Identification
To enter the "Identify" mode, select the trefoil radiation symbol by pressing
the center button from the home screen. Use this mode to identify nuclides
originating from a Gamma radiation source.
The "Identify"screen then displays and provides updated progress of
sampling, and directions as to proximity of the FLIR identiFINDER R200 to
the source in question.
The FLIR identiFINDER R200 displays directions to the user to "Keep
Distance" (ideal proximity for data collection), "Move Closer", or "Move
Farther". Ideal data sets are collected when "Keep Distance" is maintained
