The camera will periodically update the calibration status. This is
especially important if the user has disabled the automatic
calibration by clicking “Autocal Enabled.”

5.2.1 Calibration (One-Point Calibration) Non-Uniformity Correction
To optimize a thermal scene, the processor software performs NUC or 1-Point calibration of the
video images through internal calculations. To provide the best possible image, a non-uniformity
correction is performed based on information provided by factory calibration, user-commanded 1-
point calibrations, and bad pixel replacement (BPR) algorithms. Initiating a NUC activates a one-
point single-temperature correction sequence that will reset the level offset of each pixel to
improve overall image uniformity and contrast.
A NUC is performed automatically at start up, per the AutoCal setting and when the FPA
temperature transitions into another temperature zone – these zones are static with a
