LabQuest App

  • Collect buttons (, , , ) only available when the LabQuest App, , is running
  • Run Selector, , and Store Run, , buttons now located in the bottom bar
    • They are also available from the Table screen, , as well as the Graph screen, .
  • Table only displaying data from one dataset at a time
    • Run Selector changes which dataset you are viewing.
  • NEW Experiment Viewer app, (replacing some LabQuest App functionality)
    • This replaces the View Lab Instructions tab from within LabQuest App.
    • Internal sensor user guides are now accessed from the Experiment Viewer app.
  • NEW LabQuest App supports gestures (see Which gestures work with LabQuest 3 touch screen?)
    • Manually scale graphs using pinch/zoom/pan gestures.
      • Main Graph, FFT Graph, and Peak Integration Graph
    • Scroll table and dialogs using the touch-and-drag gesture (no more obvious scroll bars).

    • Columns are added to all data sets.
      • Existing datasets include an empty column for added sensors.
    • Columns for new sensors need to be added to the graphs manually.
