Graphical Analysis is available both as an installed application and as a Progressive Web App<\/a> (PWA) on some platforms. (This is also true for our Spectral Analysis and Instrumental Analysis apps.)<\/p>\n

The sensor connection process to a PWA includes an additional step compared to the installed application because you must give the browser permission to connect to the sensor before the app running in the browser can connect to it. The steps here describe that process for USB connection of a sensor to the PWA version of Graphical Analysis. (See also instructions on connecting sensors via Bluetooth<\/a>.)<\/p>\n

    \n
  1. Connect your USB sensor (or USB sensor interface) to your computer or Chromebook. If you are using a wired (BTA or BTD) sensor that requires an interface, connect the sensor to the interface now.<\/li>\n<\/ol>\n
