# Isotherms Regions

### **Isotherms Regions – Orus-L**

The Isotherms function highlights temperature ranges within the thermal image to enhance visibility of specific heat zones.

***

#### **Mode**

Select the desired isotherm display mode:

* **Disable** – Turns off isotherm overlays
* **Upper & Lower** – Highlights areas above and below defined temperature thresholds
* **Medium** – Highlights areas within a specified temperature range

***

#### **Lower Temperature (℃)**

* Enter the **lower threshold** for isotherm display (°C)

#### **Upper Temperature (℃)**

* Enter the **upper threshold** for isotherm display (°C)

> 💡 Use precise values to isolate thermal anomalies or regions of interest.

***

#### **Measurement Range**

Choose the appropriate thermal measurement range for your application:

* **-20℃ \~ 150℃** – Standard range for general thermal tasks
* **-20℃ \~ 550℃** – Extended range for high-temperature environments

***

#### **Saving Your Settings**

Click **“APPLY”** to confirm and apply your isotherm configuration.\
The thermal display will immediately reflect the new settings.

## 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/isotherms-regions.md?ask=<question>&goal=<endgoal>
```

`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.
