The Projector PRO software displays the XL2 screen in real-time via USB on the connected Windows or Mac computer. The software toolbar enables control of the XL2 with the mouse and keyboard. The background color turns from green to red according to the user-defined limits. Projector PRO offers the ability to retrieve measurement data from the XL2 without interruption to the measurement process. The entire file system of the XL2 is available while the XL2 is measuring. The complete data records of a previous day can be transferred to a local computer with drag & drop.
All Projector PRO settings can be saved in a software profile. For daily event monitoring, e.g. in a neighborhood bar monitoring project, the sound level monitoring starts automatically when the computer starts up and ends again with the shutdown. The XL2 Sound Level Meter stores the measurement data for later documentation. For precise data recording, the time of the XL2 sound level meter is automatically synchronized with the computer time. The XL2 instrument can then be kept in a protected place (such as a locked cupboard) - it no longer requires any keypresses.
