From ATZ Bilisim:
PassCheck is a visual event-triggering interface to Multiscope. A suitable event must be configured for PassCheck in order to run properly. Event properties and configurations can be adjusted using Multiset client software as usual. You must tell PassCheck, which event should be triggered when a document save action is performed. Note that PassCheck only retrieves one picture of any event even if you configure the event to record more than one frame. Events can be selected in PassCheck using "Tools --> Options". Should you ever change event settings using Multiset, there is no need to adjust anything in PassCheck software.
