18.2 Laying out measurement tool: isotherms
General
The isotherm command applies a contrasting color to all pixels with a temperature
above, below, or between one or more set temperature levels.
Using isotherms is a good method to easily discover anomalies in an infrared image.
Procedure
Follow this procedure to lay out an isotherm:
Push to display the menu system.
1
Use the joystick to go to
.
2
Push the joystick to display a submenu.3
Use the joystick to go to
.
4
Push the joystick. This will display a submenu.5
In the submenu, select one of the following:
■
Above. This will apply a contrasting color to all pixels with a temperature
above one or more set temperature levels.
■
Below. This will apply a contrasting color to all pixels with a temperature
below one or more set temperature levels.
■
Interval. This will apply a contrasting color to all pixels with a temperature
between two or more set temperature levels.
■
Humidity. This will apply a contrasting color to all pixels with a tempera-
ture below a threshold calculated by humidity parameters.
■
Insulation. This will apply a contrasting color to all pixels with a temper-
ature below a threshold calculated by insulation parameters.
This will display a flag in the temperature scale. To change the temperature
level, tap and drag the flag up or down. See the image below.
