Microbolometer Calibration

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 required mode in the Calibration Mode  item.

M mode (manual)

  • Close the lens cover (12) and press the ON/OFF (3) button briefly.
  • Open the cover after the calibration is completed.

SA mode (semi-automatic)

  • Press the ON/OFF (3) button briefly to activate calibration.
  • There is no need to close the lens cover (internal shutter covers the microbolometer).

A Mode (automatic)

  • The riflescope is calibrated autonomously according to the software algorithm.
  • There is no need to close the lens cover (internal shutter covers the microbolometer).
  • In this mode, the riflescope may be calibrated by the user with the ON/OFF (3) button.

Note: a display image freezes until the calibration is in progress.
