# F10 - test parameter configuration

URL: https://irs.systems/en/docs/ltt/documentation/ltt-gui-manual/lttgui/dialogs/f10testparameterconfiguration

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](/en/docs/ltt/documentation/ltt-gui-manual/lttgui/dialogs/f3projectwizard/testgroupsconfiguration).

> You first need to define one or more test groups in [project wizard](/en/docs/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](/en/docs/ltt/documentation/ltt-gui-manual/lttgui/systemerrors) if one of those limits are violated.
