XIV. Calibration
When the image is degraded or uneven, it can be improved by calibration. Calibration can
balance the background temperature of the detector and eliminate the defects in the image.
There are three calibration modes: Automatic (A), Manual (M), and Background (B).
Select the required mode from Calibration on the main menu.
 Automatic (A): The device conducts automatic shutter correction through software
algorithms with the lens cap removed (the sensor automatically closes the internal shutter).
In Automatic mode, you can also press the power button (5) to manually perform shutter
correction;
 Manual (M): On the home screen, press the power button (5) for manual shutter
correction with the lens cap removed (press the power button (5), and the sensor
automatically closes the internal shutter);
 Background (B): Close the lens cap and press the power button (5). A prompt is displayed
on the home screen: Cover lens during calibration. Background calibration will begin in 2s.
After calibration, remove the lens cap.
XV. Zeroing
TUBE TL35 SE uses the “freezing” zeroing method. It is better to perform zeroing in
environments within the operating temperature range of the scope.
 Fix the scope on the weapon with a frock clamp (For details, refer to Chapter VII.
Mounting and Usage);
