Calibration eliminates image flaws (such as vertical bars, phantom images, grainy field of
view, etc.) by equalizing the microbolometer background temperature.
There are three calibration modes: Manual (M), Semi-Automatic (SA) and Automatic (A).
Select the desired mode in the menu option Calibration Mode .
M Mode (Manual).
Close the lens cover.
Press the ON/OFF (11) button briefly.
Having finished calibration, open the lens cover.
SA Mode (Semi-Automatic).
Calibration is activated with a short press of the ON/OFF(11) button.
You do not have to close the lens cover (the microbolometer is closed with an internal
shutter automatically).
A Mode (Automatic).
The device calibrates by itself according to the firmware algorithm. You do not have to
close the lens cover (the microbolometer is closed with an internal shutter automatically).
User assisted calibration with the ON/OFF(11) button is also allowed in this mode (as in
the Semi-Automatic mode).
