10. After the experiment starts running, the green triangle should turn into an icon (black square) for stopping the experiment. But if this does not happen (for whatever reason), the fallback solution for stopping the experiment is the "Stop all" option offered through the small Quanser icon at the bottom right panel in Windows. Ultimately there is the RED BUTTON if nothing else works to stop the experiment, this will switch off the amplifier.
11. Note that if you want to record the measured data for later analysis (which you will certainly do), the routes that you are familiar with from purely simulation projects may not work here. The reason is that while using the Quanser QUARC system, you are running the Simulink model in [External Mode](https://www.mathworks.com/help/sldrt/ug/simulink-external-mode.html), which prevents from using some Simulink functionality. In particular, if you [use Simulink scope block(s) for logging the data](https://www.mathworks.com/help/sldrt/ug/set-scope-parameters-for-logging-to-file.html), which is a common route, increasing the parameter called `Limit data points to last` will have no impact on how long the sequence of measurements will be stored in Matlab workspace (but do not forget to tick off the `Log data workspace` option and insert the variable name). If you ignore this issue, you may easily leave the lab assured that you stored a minute or two of experimental data only to discover at home that only the last few seconds have been saved. In order to prevent this, the `Duration` parameter needs to be changed somewhere else. Namely, go to manu `Code`, submenu `External Mode Control Panel`. Click on `Signal & Triggering` and change the `Duration` parameter there. If you need more on this, have a look at [the secion on Data Collection in QUARC manual](https://docs.quanser.com/quarc/documentation/quarc_data_collection.html) but if you are happy with logging to the variables in Matlab workspace through the Simulink scope blocks, you should be fine now.
