3.8 Camera Features
3.8.1 Application Modes
The Argus
®
Mi-TIC has two application modes:
o
FIRE
A white-hot grey and colour scale, expanded to cover the
dynamic range of the scene. Colourisation is added
gradually at scenes temperatures above 150
°
C. The colour
changes through orange (600 °C) to saturated red at
approximately 1000 °C. The colour reference bar is marked with 4
graduations allowing the temperature to be quickly assessed.
o
SEARCH or OVERHAUL
A white-hot grey scale, expanded to cover the dynamic
range of the scene. Red colourisation is added to the
hottest part of the scene, regardless of absolute
temperature. Where there is no significantly warmer area,
no red shows.
The camera starts up in Fire mode*. On 3-button cameras, to toggle
between the application modes, press the function button assigned to
application mode toggle. By default, this is the centre function button.
See section 4 for how to configure the function buttons.
*Except the camera type MI-160-S which starts up in search mode.
3.8.2 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 4).
Notes
:
•
The camera can measure scene temperatures between 0 and
+1100
°
C (32 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.
