16.3 Creating & setting up an isotherm
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 create and set up an isotherm:
To go to the mode selector, push the button to the right of the joystick.
1
In the mode selector, select Camera and push the joystick.
2
To create an isotherm, select Isotherm in the toolbox and push the joystick.
This will display a triangular indicator on the temperature scale.
3
To change the temperature level, do the following:
1 Select Level .
2 Push the joystick.
3 To select the temperature level you want to use, move the joystick
up/down.
4 To confirm, push the joystick.
4
To specify the type of isotherm, select one of the following and push the
joystick:
■
Above , i.e., the isotherm color is only applied to pixels above a set
temperature level.
■
Below , i.e., the isotherm color is only applied to pixels below a set tem-
perature level.
5
To specify the color that will be applied to the pixels in Step 5 above, do
the following:
1 Select Color .

If the image is completely covered with an isotherm color (green, red, etc.), it indi-
cates that the isotherm is set to a temperature level outside the temperature scale
of the image.
