# Isotherms Regions
### Configuration
#### 1. Enable
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.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.gremsy.com/payloads/orus-l/software-configuration/web-setting-app/ir-camera/ndaa-version/isotherms-regions.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
