15.4 Adjusting an image
General
An image can be adjusted automatically or manually. You use the button
to switch between these two modes. Note that this only works in live mode and not
in preview/archive mode.
Example 1
This figure shows two infrared images of cable connection points. In the left image
a correct analysis of the left cable is difficult to do if you only auto-adjust the image.
You can analyze the left cable in more detail if you
■
change the temperature scale level
■
change the temperature scale span.
The image on the left has been auto-adjusted. In the right image the maximum and
minimum temperature levels have been changed to temperature levels near the object.
On the temperature scale to the right of each image you can see how the temperature
levels were changed.
