# F10 Test Parameter Configuration

In this dialog you can do several things:

* set the maximum runtime your your test run
* set the minimum and maximum temperature of your temperature sensor(s)
* set the minimum, maximum and nominal voltage of your power supply/ies
* defined TCC <> operation mode mappings
* set operation mode parameters

All those settings are provided per [test group](https://docs.irs.systems/ltt/documentation/ltt-gui-manual/lttgui/dialogs/f3projectwizard/testgroupsconfiguration).

{% hint style="info" %}
You first need to define one or more test groups in [project wizard](https://docs.irs.systems/ltt/documentation/ltt-gui-manual/lttgui/dialogs/f3projectwizard) before you can use this dialog.

**Runtime**

When a test station reaches the runtime you entered here it will automatically stop.

**Temperature and voltage limits**

A test station will stop with a [system error](https://docs.irs.systems/ltt/documentation/ltt-gui-manual/lttgui/systemerrors) if one of those limits are violated.
