NUC Shutter Settings

The non-uniformity correction (NUC) of the signal is a complex electronic process,
which requires a uniform temperature body in front of the detector or the objective
lens.
For the convenience of the user, the device has a built-in motorized mechanism for
performing the NUC procedure by automatically dropping a miniature shutter in front
of the detector. This process takes less than a second and is accompanied by acoustic
noise resembling a click.
Selecting the NUC Shutter Settings changes the NUC shutter mode between Shutter
On (internal) and Shutter Off (external).
In situations requiring maximum suppression of the acoustic noise, the device can op-
erate with shutter OFF in External shutter mode, which isolates the operation of the
motorized mechanism.
When the External shutter mode is activated, the motorized mechanism of the shutter
is OFF, the Auto NUC function is deactivated.
In that case the function of the mechanism should be performed by the user, who must
cover the objective lens, before pressing
a hand or the protective cap, otherwise the image of the display will resemble the
negative effect of the observed scene.
Upon power on, the device automatically performs two consecutive NUC-cycles.
During this period of time it is desirable to cover the objective lens. These actions are
necessary only when the External shutter mode is activated.
