Working with images and folders16
You use the A/M button to switch between these two modes.
16.7.2 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 ana-
lyze this cable in more detail if you
• change the temperature scale level
• change the temperature scale span.
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.
16.7.3 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 temper-
ature levels have been changed to temperature levels near the isolator. This makes it eas-
ier to analyze the temperature variations in the isolator.
16.7.4 Changing the temperature scale level
