Calibration & Zeroing – XBoat

Before rowing with XBoat Smart Oarlocks, be sure to calibrate and zero each seat in the boat. This process ensures that the oarlocks are recording accurate angles.

🛑

Calibrate & Zero when

Initially installing Smart Oarlocks

A different XPod is attached to an already-configured oarlock

The angle reference is moved or tightened

Spacer heights have changed

✅

No action is required when

A different rowing monitor is paired to already-calibrated & zeroed oarlocks

💡 When in doubt, re-calibrate and zero it out!

Start New Calibration (5 seconds)

1) Tap the angle indicator dial and select NEW CALIBRATION to force the Smart Oarlock to re-detect angles.

Force a calibration when:

A different XPod is attached to an already-configured oarlock

The angle reference is moved or tightened

Spacer heights have changed

Calibrate Angle Sensor (15 seconds)

Swinging the oarlock allows the XPod to detect the field of the Angle Reference it sits above, providing precise angle measurement in seconds

1) Smoothly swing the oarlock around the pin in a 180° arc, from -90° to +90° relative to the angle reference

2) Calibration is complete when angles appear on the angle indicator dial. As a rule of thumb, most calibrations take no more than 5 swings

Zeroing (30 seconds)

💡

Zeroing sets the current angle of the Smart Oarlock to 0 degrees and stores this information inside the Oarlock Force Sensor, making Rowing Monitors interchangeable without re-zeroing

1) Tap the Oarlocks menu tile on a rowing monitor with connected and calibrated Smart Oarlocks

The Oarlocks menu is in the bottom center menu tile

2) Swing the Oarlocks a few degrees to activate the angle sensor. Once angles appear in the angle indicator dial, the sensor is active

When the dial says “swing gate”, it must be moved to activate the angle sensor

3) Hold a straight edge against the surface of the oarlock. In sculling boats, you may use a skinny oar with a straight shaft as a convenient angle zeroing device

4) Once level, check the angle of the Oarlock. If the oarlock has not been Zeroed before, it will likely have a small non-zero angle value

The angle indicator shows -5.1 degrees when the oarlock is fixed in the desired zero position

5) Tap Zero Angle to set the angle at the current oarlock position to 0°

By pressing Zero Angle, the current position now measures 0°
