- Once the **AMASS Wand** (pictured below) arrives in the mail, it is unfolded and the calibration process can start. NOTE: make sure the little black dots on each marker are pointing down, towards the handle. To calibrate a volume, you get all the cameras plugged in and start Capture2D. You then **Connect** to the cameras and set the duration to 20 seconds (or more if lots of cameras are used). Finally, click **Start Recording** and wave the wand all around the capture volume - high, low, spinning, waving, and near the floor.\\ | - Once the **AMASS Wand** (pictured below) arrives in the mail, it is unfolded and the calibration process can start.
