VWAnalyzer Operating System

v2.25

The operating system file (.obj extension) can be downloaded and saved to a VWA with the USB cable. The operating system should automatically load the first time power is applied to the VWA after the file has been saved to the device. An operating system may contain updates to the sensor library, additional features, or software fixes. It is recommended that measurement data and the VWA project file should be saved before updating an operating system.
