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.
3.8.3 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).
•
Low Sensitivity Mode
The Argus
®
Mi-TIC will automatically switch to Low Sensitivity
mode when higher temperatures have been detected, a small
green triangle symbol will be displayed in the top left corner to indicate
this. The image produced will still be clear with lots of detail, although
some additional noise will be visible in the cooler areas of the scene.
The temperature range for this mode is up to 400
°
C (750
°
F).
•
Extended Low Sensitivity Mode
The Argus
®
Mi-TIC will automatically switch to Extended Low
Sensitivity mode when higher temperatures have been detected,
a small green triangle symbol will be displayed in the top left corner to
indicate this. The image produced will still be clear with lots of detail,
although even more noise will be visible in the cooler areas of the
scene. The temperature range for this mode is up to 1100
°
C (2000
°
F).
3.8.4 Zoom
A short press on the left-hand function button operates the zoom
feature. The zoom symbol, magnifying glass, will appear on the left-
hand side of the display.
