Operation 7
• Manual mode: This mode allows manual adjustments of the temperature span and
the temperature level.
7.14.2 When to use Lock mode
A typical situation where you would want to use Lock mode is when looking for tempera-
ture anomalies in two items with a similar design or construction.
For example, if you are looking at two cables, where you suspect one is overheated,
working in
Lock mode will clearly show that one is overheated. The higher temperature in
that cable would create a lighter color for the higher temperature.
If you use Auto mode instead, the color for the two items will appear the same.
7.14.3 When to use Manual mode
7.14.3.1 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.
7.14.3.2 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.
