Access the control panel

  1. Connect the Smart Cart Trigger Dropper to a Smart Cart.
  2. Connect the Smart Cart to SPARKvue.
  3. Select Trigger Dropper from the list of Quick Start Experiments. You will automatically be taken to a file containing a graph display and a Trigger Dropper control panel.

Launch options

  • Trigger Type

    Use this to trigger the plunger or dropper based on the Smart Cart's position relative to its starting point or a duration of time after starting data collection.

  • Trigger Value

    Tip

    Set a Position Based measurement with a value of 0. Start data collection, roll the cart backward until the blinking red LED on the cart turns green, then roll it forward. The Trigger Dropper activates when the cart returns to its starting position.
