# LTT Overview

<figure><img src="/files/AI2g8bMBovPYcrk5hvS8" alt=""><figcaption><p>IRS LTT GUI</p></figcaption></figure>

The IRS LTT GUI (Life Time Tester Graphical User Interface) is a powerful graphical user interface specifically designed to manage and monitor long-term electrical tests on various electronic control units.

&#x20;The outstanding feature of the IRS LTT software is the parallel operation of multiple DUTs (Devices Under Test). This function allows for the simultaneous testing of multiple devices, saving time and costs while significantly increasing the efficiency of your testing processes.

&#x20;A typical application area of the IRS LTT software are lifetime test (LTT) systems. These systems conduct electrical endurance tests on various devices and simulate realistic environmental conditions such as temperature and humidity to evaluate the ageing process or the lifespan of the devices. A particularly common application area is the testing of automotive control units, where the devices are tested for reliability and durability under real conditions.

&#x20;The IRS LTT software is supplied as standard with every IRS service lifetime simulation system, but can also be purchased separately and independently of the system - for flexible and efficient use in different test environments.

## 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.irs.systems/ltt/documentation/readme.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.
