Magnetometer calibration

Open Setting → General. These switches control device-wide settings. The Tracker detail page has a separate button for calibrating one Tracker's magnetometer.

Magnetometer switch

The Magnetometer switch enables or disables the magnetometer for the Tracker set. Its state is sent through the USB dongle; if the receiver is offline, the setting will sync when the receiver reconnects.

The interface warns that magnetometer can cause more drift. Do not turn it on as a routine first-run fix. Only change it if you are following a tested setup instruction or troubleshooting step.

Calibrate one Tracker's magnetometer

  1. In Device, click the Tracker you need to calibrate.
  2. Check that the Tracker is online and its Magnetometer status is On. The calibration button stays disabled if the system or this Tracker's magnetometer is off.
  3. Click Magnet Calibration.
  4. Click the ? help icon and copy the figure-eight movement with the Tracker.
  5. Keep moving the Tracker until the sphere fills or the counter reaches 300/300. Sampling stops automatically at 300 points.
  6. Click Confirm to close the calibration window.
Example Magnet Calibration dialog at 000/300; no samples collected or successful calibration implied.

If the counter does not move: keep the Tracker online and magnetometer On. Reopen the calibration window and follow the displayed figure eight. The number counts collected points, not seconds.

Issues found while exploring

  • One switch controls all Trackers' magnetometers, while calibration opens for a selected Tracker. The interface does not make this difference clear, and it warns that enabling the magnetometer can add drift.
  • The figure-eight directions are inside a small help popover. A new user may miss the instructions before starting.

For vibration controls, see Haptics and vibration.
