"Too Few Markers" flag:
1. Position the tool inside the characterized measurement volume, with the markers facing the
Position Sensor.
2. Cover one or more markers, without touching them.
The Position Sensor will no longer be able to detect the covered markers.
If the Position Sensor cannot detect the minimum number of markers, NDI ToolBox will display
the message "Too Few Markers" and will not report a transformation.
"Exceeded Maximum Marker Angle" flag:
1. Position the tool inside the characterized measurement volume, with the markers facing the
Position Sensor.
2. Turn the tool gradually until the markers are no longer facing the Position Sensor.
Once a marker has exceeded the maximum marker angle, NDI ToolBox will display a blue
indicator in the Not Used section of the marker information.
