Calibration Mode

Calibration mode selection.

Calibration enables the device to equalize the microbolometer background temperature and eliminate the image flaws (such as vertical bars, phantom images, etc.).

There are three calibration modes: Manual, Semi-Automatic and Automatic.

The selected calibration mode is displayed in the status bar (see Status Bar section).

Select the required mode in the Calibration Mode menu item:

1. Press and hold the MENU (3) button to enter the main menu.
2. Use the UP (4)/DOWN (2) buttons to select the Calibration Mode  icon.
3. Press the MENU (3) button briefly to enter the submenu.
4. Use the UP (4)/DOWN (2) buttons to select one of the calibration modes described below.
5. Press the MENU (3) button briefly to confirm the selection.

M mode (Manual)

• Close the lens cover (7).
• Press the ON/OFF (5) button briefly.
• Open the lens cover (7) after the calibration is completed.

SA mode (Semi-Automatic)

• The user independently determines the need for calibration (according to the image being observed).
• 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).
• In Automatic calibration mode a countdown timer will appear instead of the calibration mode icon 3 seconds before automatic calibration begins.

Notes:

• During calibration, the image on the display briefly freezes for up to 1 second.
• The selected calibration mode is saved after restarting the device.
