Once you have completed the set-up steps section 3, the system is ready for operation.
Definitions:
The top of the camera is the end with the focusing knob. The side with the large opening (aperture) is the face or front. The opposite side, with the cable connector, is the back.
Position the camera head so it is approximately centered over the area to be scanned with its face toward the subject and the top aligned with the edge you want at the top of the display. The face of the camera head should be parallel to the surface of the subject.
The area scanned by the camera depends on the distance from the camera to the subject. Just like a "box" camera, the further from subject, the larger the field of view. WinTES95 "computes" the field of view when the distance from the camera to the object (focus) is entered in the correction menu. Set the camera head at a distance appropriate for the size of the subject. It should be no closer than 1.75 inches to the subject.
The focusing knob has a scale showing focal length in inches and mm. For an initial focus, turn the knob so the index mark on the top of the camera matches the scale marking for the distance from the face of the camera to the surface of the subject.
Start WinTES95 by double clicking on the WinTES95 icon.
If the camera has been set-up previosly the system will configure itself and run WinTESCheck automatically. After WinTESCheck completes its verification you may begin taking scans. To begin scanning select Single Scan or Continual Scan and click on the Start "button". The default value for Delay is 20 seconds. This is the time from the start of one scan to the start of the next scan. The user can select values to best suit their application.
While the system is scanning you may improve the focus by making small adjustments of the focusing knob until edges appear sharp. Remember, however, that heat will flow from one object to another so thermal images may appear "smeared" when compared to photographic images. (See Section 8 for suggestions on focusing and framing.)
Note
Single scan will take one image, then stop. Continual scan will periodically scan, depending upon delay, until commanded to Stop. You can stop either process at any time by pressing STOP. Selecting single scan while in the middle of a multi-scan will cause the scanning to stop at the end of the current scan.
