The NTI 600 000 439 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 sound level meter can then be kept in a protected place (such as a locked cupboard) - it no longer requires any keypresses.
The XL2 Projector PRO software is a free download for all registered XL2 customers. Required is a computer with Windows 7, 8, 10 or higher or Mac OS 10.8 or higher.
The "XL View" window presents sound levels in large size on the connected computer screen. Users may select to view one, two or three sound pressure levels. Exceeding levels are presented with a pre-warning amber or alarming red color. To access the XL View, a Projector PRO Option must be installed on the XL2 Sound Level Meter.
