Achieving a good thermal image

7.2.2 Example 2

Here are two infrared images of an isolator in a power line. To make it easier to analyze
the temperature variations in the isolator, the temperature scale in the right image has
been changed to values close to the temperature of the isolator.

7.2.3 Manually adjusting the temperature scale

1. Tap the menu button
2. Tap Temperature scale
the temperature scale.
3. To enhance the details of a certain point of interest in the image, tap that point on the
screen. The image will be auto-adjusted based on the thermal content of the area
around the tapped point.
4. To change the level, scroll the wheel up/down.
5. To change the span, do the following:
5.1. Tap the temperature limit you want to keep unchanged. This locks the limit.
5.2. Scroll the wheel up/down to change the value of the other temperature limit.

7.2.4 Locking the temperature scale

You can lock the temperature scale.
• To lock the temperature scale, tap the upper and the lower temperature limits.
• To unlock the temperature scale, tap the temperature limits again.
Note
• When a temperature limit (upper and/or lower) is locked, the auto-adjust by touch
function is disabled.
• If you switch to automatic mode, the temperature scale will automatically unlock.
A typical situation where you would lock the temperature scale is when looking for tem-
perature anomalies in two items with a similar design or construction.
For example, you have two cables, and you suspect that one is overheated. With the
camera in automatic mode, direct the camera toward the cable that has a normal temper-
ature. Then activate the manual mode and lock the temperature scale.
When you direct the camera, with the temperature scale locked, toward the suspected
overheated cable, that cable will appear in a lighter color in the thermal image if its tem-
perature is higher than the first cable.
If you instead use the automatic mode, the color for the two items might appear the same
despite their temperature being different.

7.2.5 Showing/hiding the temperature scale

In some situations, you may want to hide the temperature scale for a better view.
