Microbolometer Calibration
Calibration eliminates image flaws (such as vertical bars, phantom images, grainy field of
view, etc.) by equalizing the microbolometer background temperature.
During calibration, the image on the display briefly freezes for up to 1 second.
There are three calibration modes: Manual (M), Semi-Automatic (SA) and Automatic (A).
Select the required mode in the Calibration Mode menu item.
M mode (Manual).
Close the lens cover.
Press the ON/OFF (5) button briefly.
Open the lens cover after the calibration is completed.
SA mode (Semi-Automatic).
Press the ON/OFF (5) button briefly to activate calibration.
There is no need to close the lens cover because an internal shutter covers the
microbolometer automatically.
A mode (Automatic).
The device is calibrated autonomously according to firmware algorithms.
There is no need to close the lens cover because an internal shutter covers the
microbolometer automatically.
In this mode, the user can still choose to calibrate the device using the ON/OFF (5) button
if required (as in the SA mode).
