Focusing and Capturing an Image
Point the Imager at the object or area of interest, focus by turning the focus
control ring until the infrared image displayed on the LCD is as clear as
possible, and then press and release the trigger. The Imager displays the
captured image and a menu. The menu allows image storage, image setting
adjustments, and recording of audio annotations for .is2 file format. To cancel
image storage and return to live viewing, press and release the trigger.
Note
Minimum focus distance for infrared camera (with the standard lens)
is 15 cm (approx. 6 inches). Minimum focus distance for visible
(visual) light camera is 46 cm (approx. 18 inches).
Note
The Imager can save the image as a simple picture or as a
radiometric image that allows further temperature analysis. To
change the saved image format, see the “Setting File Format” section
later in this manual.
Note
When IR-Fusion
is enabled, adjusting the IR focus control will align
the IR and visible light images on the LCD. When the IR image is
properly focused, the images should be almost perfectly aligned. This
functionality provides an easy method to get a good focus on the IR
image. Because of image parallax and minimum focus specifications,
the minimum distance for an aligned IR-Fusion
image is
approximately 46 cm (18 inches).
Pressing the softkey labeled
Settings,
within the Image Captured section,
allows modification of image characteristics such as palette, picture-in-picture,
and range in .is2 format files only. Refer to the appropriate setting section for
operational details.
Saving Imager Data
The Imager saves displayed data on an SD memory card placed into the
camera. See the “Changing the SD Card” section for inserting and ejecting an
SD memory card. The file format set on the Imager determines how the
measured information is stored on the SD memory card. To store Imager data:
