Calibration allows levelling of the background temperature of microbolometer and eliminates image flaws such as frozen image, vertical stripes etc.). There are three calibration modes: manual (M), semi-automatic (SA) and automatic (A). Select the desired mode in the main menu option Calibration Mode .
Mode M (manual)
- Close lens cover and press ON/OFF (11) button briefly.
- Having finished calibration, open the lens cover.
Mode SA (semi-automatic)
- Calibration is activated with a short press of ON/OFF (11) button.
- You do not have to close lens cover (microbolometer is closed with internal shutter automatically).
Mode A (automatic)
- The riflescope calibrates by itself according to the software algorithm.
- You do not have to close lens cover (microbolometer is closed with internal shutter automatically).
- User assisted calibration with ON/OFF (11) button is allowed in this mode (as in semi-automatic mode).
Note: a display image freezes until the calibration is in progress.
