2.4.1. Calibration Files
The menu Tools, Extended and Reimport calibration files enables to boot the calibration data for the
currently connected TIM.
2.4.2. Correction of Camera Calibration
Due to the thermal drift of bolometers all measuring IR cameras need an offset correction every few minutes.
This correction is done by a motor driven motion of a blackened metal piece (so called flag) in the front of the
image sensor. In this way each image element is referenced with the same temperature. During those offset
calibrations thermal cameras do not measure (self referencing within 250 ms). In order to minimize this
disturbing effect the offset correction can be initiated manually or by an external control pin at a suitable point of
time.
In the Devices and Refresh flag menu or via the Icon on the toolbar the
Flag (Shutter) can be refreshed manually.
The automatic correction of camera can also be set by defining minimum or
maximum intervals via the menu Tools, Configuration and Device. The
options Flag automatic and Min. Interval control that the flag will not be
released before a given time period even though it might be required by the
imager. If the Max. Interval is defined the flag will always be released after a
certain time period even if not required by the imager.
