14. NON-UNIFORMITY CORRECTION
A non-uniformity correction (NUC) allows a thermal imager’s sensors to
correct its pixels and eliminate any image defects caused by pixel drift.
A NUC will be performed automatically each time the MINI MH25V2 is
powered on.
The MH25V2 has two NUC modes, automatic and manual. The selected
NUC mode, A or M, appears in the status bar. For instructions on setting the
NUC mode in the main menu, see Setting Menu > NUC Mode on page33.

while in Automatic(A) mode.
