Blackbody reference temperature Marker size and location
The marker is the location of the Calibration Reference Source seen by the infrared
the FevIR Cam within its field of view. This must be outside the general person
Scanning area that has or will be defined. The Calibration Reference Source
Scanning area is designated by a circular yellow area tool. This area measurement
tool must be placed over the central active area of the Calibration Reference Source
with the FevIR Cam aligned directly to view down the centre of the anti-reflection
metal tube. The circle should encompass the uniform area of the Calibration
Reference Source to enable the system to include those values in the calibration
algorithms. A minimum size of area of 20×20 pixels is required to conform with ISO
standard protocols. If this cannot be set within the Calibration Reference Source
uniform surface view, reduce the distance between the FevIR Cam and the
Calibration Reference Source.
Th
e “Auto System Monitor” feature allows the user to select an automated check of
the system stability during normal operation. When the system detects poor
reference stability it will indicate this with an exclamation mark. (See page 23.)
Note that when first turned on both the Calibration Reference Source and the FevIR
Cam will have poor thermal stability as they warm up and hence the alarm condition
will be displayed for around 2 minutes.
Note:
When the exclamation mark is showing the system measurement is inhibited and the
system is not available for Scanning.
