Device Calibration

Calibration falls into two types: gyroscope zero-bias calibration is normally only done after first use, after firmware maintenance, or when something is clearly wrong; full reset and wearing calibration should be done after each re-wearing and after restarting the app.

Gyroscope Zero-Bias Calibration

1. Wear the trackers for about 20 minutes before calibrating to reduce errors caused by temperature changes.
2. Keep the trackers on, place all devices into the charging dock as soon as possible, and put the dock on a stable, level surface.
3. Double-press the SW0 button on the dock to enter calibration mode; you can also double-press the side button on each tracker.
4. Keep the time from removing the trackers to finishing calibration within about 1 minute. Do not touch or move the trackers during calibration.
5. Calibration is complete when the indicator blinks, stays on for about 6 seconds, then blinks 3-4 times.

Double-press the SW0 button on the dock to start calibration.

Start from the calibration entry before each use.

Before Each Use

1. In SlimeVR, select "Drift reset - Full reset", stand upright and stay until the countdown ends.
2. Select "Wearing - Body", strike the skiing pose and stay until the countdown ends.
3. With 8 or more points and foot trackers assigned, also run "Wearing - Feet" and rise onto your toes to complete foot orientation calibration.
4. After entering VRChat, keep your legs straight and stable, then complete the in-game calibration and model skeleton alignment.

Full reset and wearing calibration.

Align the devices with the model parts before calibrating.

You can adjust the skeleton for different models.

Continuous Calibration (VRChat)

Continuous calibration is set up while wearing VR and inside VRChat. Save the standing, sitting, and lying or reclined poses in order; each step follows the interface countdown and confirmation result.

Open settings and configure continuous calibration.

Confirm the trackers are on.

Stand straight and complete the full reset.

Strike the skiing pose, then reset wearing.

Stand relaxed and save the pose.

Sit or squat against a wall and save the pose.

Lie down or recline and save the pose.

Click finish after all poses are saved.

Full reset, heading axis and wearing calibration notes.

Still Offset After Calibration

First check whether a device has become loose or shifted during movement, then re-run the full reset and wearing calibration. Do not try to replace calibration by changing several software parameters at once; if it still cannot be resolved, see Troubleshooting.
