Measurement pane can be accessed under the Tools tab.
The Accuracy Tool is used to check calibration quality and tracking accuracy of a given volume. There are two tools in this tab: the Volume Accuracy tool and the Marker Measurement tool. The Accuracy tools are available under the Accuracy Tools tab in the Measurements pane.
The Probe tab is used with the Measurement Probe Tool Kit. See Measurement Probe Kit Guide for specific instructions.
This section of the pane displays tracking information of the probe. It displays both the real-time tracking and recorded samples. If multiple samples are collected, the distance and angle between the sampled points will be calculated and displayed.
