14.5 Adjusting an infrared image
14.5.1 General
An infrared image can be adjusted automatically or manually. When manual image adjust
mode is active, the status icon
is displayed.
• In live mode, push the button
to switch between automatic and manual image adjust
modes. You can also switch between the modes by touching the temperature scale
on the screen.
• In preview/edit mode, manual image adjust mode is active.
14.5.2 Example 1
This figure shows two infrared images of cable connection points. In the left image, a cor-
rect analysis of the circled cable is difficult if you only auto-adjust the image. You can an-
alyze this cable in more detail if you:
• Change the temperature scale maximum limit.
• Change the temperature scale minimum limit.
• Change the temperature scale maximum and minimum limits.
In the left image, the image is auto-adjusted. In the right image, the maximum and mini-
mum 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.
14.5.3 Example 2
This figure shows two infrared images of an isolator in a power line.
In the left image, the cold sky and the power line structure are recorded at a minimum
temperature of –26.0°C (–14.8°F). In the right image, the maximum and minimum tem-
perature levels have been changed to temperature levels near the isolator. This makes it
easier to analyze the temperature variations in the isolator.
14.5.4 Procedure
Follow this procedure:
1. In live mode, push the button
to enter manual image adjust mode.
