Calibrating the compass

To calibrate the integrated digital compass, open the Compass app, then hold the TDC6 handheld flat at arm's length and move it horizontally through a "figure of eight", turning it over as you move through the loops.

Using the TDC6 handheld on the magnetic pole bracket mount system may cause interference with the device's internal compass. If your workflow requires the device's internal compass, Trimble recommends using the device bracket with tapered quick pin release in lieu of the magnetic mount system.
