Direct Temperature Measurement
The camera allows the operator to view the average
temperature of the centre spot of the scene (defined by the
target markings). The temperature reading is displayed in the
bottom right-hand corner of the display. This system is
intended to give the operator the ability to detect possible
hazards such as hot gas bottles or tanks, heat signatures of
people of objects, and to compare temperatures.
The temperature measurements feature can be changed between degrees Celsius or
degrees Fahrenheit by using the PC Configuration Tool software (see section 6.2).
In ‘Fire’ application mode, a green column against the temperature reference scale also
shows the spot temperature.
Notes
:
•
The camera can measure scene temperatures between -40
°
C and +1100
°
C (-40
°
F and
+2000
°
F).
•
The object being measured must fully fill the target marks to get a good reading.
•
If the temperature is higher than the maximum, the display will show “
1100+C
” in red.
•
If the temperature is lower than the minimum, the display will show “----”
•
Different types of materials have different infrared emission characteristics. This will
affect the accuracy of the temperature reading. Variations can also be caused by the
distance from the object. This temperature measurement must be regarded as an
indication and not a guaranteed reading.

Tri-Mode Sensitivity
The Argus
®
Mi-TIC has three levels of sensitivity: High, Low and Extended Low. These
levels provide the user with a thermal image over the widest possible temperature
range. The Argus
®
Mi-TIC will switch to the optimum level of sensitivity automatically
and will indicate when it is not in high sensitivity mode by displaying a green coloured
solid triangle symbol at the top left of the display.
•
High Sensitivity Mode
The Argus
®
Mi-TIC will operate in High Sensitivity mode under normal operating
conditions. This mode produces a clear image with lots of detail and low levels of noise.
The temperature range for this mode is between
−
40
°
C and 150
°
C (
−
40
°
F and 302
°
F).
