To set a fixed duration with start and end times, the following steps are required: First, click on the Start button to specify whether the survey should start immediately or later. Don’t worry, clicking on the Start button will not start the survey automatically, you will go through 3 pages where you can check the settings of the survey and set the start time among others.
As soon as the survey is in online mode, i.e. has been started, you can define when the survey should be paused/ended automatically by clicking on the Pause button. Again, clicking the Pause button does not automatically terminate the study, it opens a pop-up window where you can specify whether the survey should be paused immediately or at a later time.
