Turn the Isotherms feature On or Off using the toggle switch.
2. Gain
Select the appropriate Gain mode based on the expected temperature range of the target.
3. Units
Choose the temperature unit (e.g., °C or °F).
4. Configure Isotherm Regions
For each enabled region, configure the following parameters:
Minimum Temperature – Lower limit of the temperature range.
Maximum Temperature – Upper limit of the temperature range.
Color A – Starting color of the temperature range.
Color B – Ending color of the temperature range.
Colorization Mode – Select the desired color mapping method:
Linear RGB
Linear HSV
Standard
Non-Linear
Single Color
Note:
To ensure a smooth color transition between adjacent regions, set the Minimum Temperature of the current region equal to the Maximum Temperature of the previous region.
Leave any unused regions (such as Region 4 and Region 5) Disabled.
5. Apply Settings
Click Apply to save and activate the Isotherms configuration.
Example
The following configuration creates three continuous temperature regions:
Region
Temperature Range
Color
Region 1
0°C – 30°C
Blue → Green
Region 2
30°C – 60°C
Green → Yellow
Region 3
60°C – 120°C
Yellow → Red
This configuration provides a continuous color gradient across the thermal image, allowing operators to quickly distinguish different temperature levels and identify hot spots.
