What to do when a Calibration Fails

If a calibration failure occurs, it’s important to consider several factors that might be contributing to the issue. Revisiting aspects like coverage size, the RF environment, and calibration methods can help you identify and resolve roadblocks causing the calibration failure.

Establish a Clear Line of Sight

  • Walk around the deployment space to identify any obstacles or blockages that are disrupting the Mobile’s line of sight to the Anchors. Adjust the Anchor layout to enhance their visibility to the Mobile.

  • Ensure that the Mobile always has a clear line of sight to a minimum of four Anchors in the deployed area.

Begin and End with the Mobile on the Floor

  • The Mobile must be on the floor throughout the entirety of the calibration process.

  • Ensure that it maintains visibility to the Anchors at all times – even when the Mobile is stationary on the floor.

  • Choose an open area with minimal obstructions to start and end the calibration.

Check the RF Channel and Change if Necessary

RF interference can negatively impact performance, including disrupting the calibration process.

For more information on how to check and change the RF channel, please read our help article: Conducting RF Scans to Find a Clear Channel.

Adjusting your System’s Listening Distance

If you have relocated your system or expanded the tracked area, the system may not be properly configured to function in the new space. To ensure it works correctly over the larger area, including during calibration, increase the Set Max Range value.

For guidance on how to adjust the listening distance of your system, please read the following help article: Selecting the Right Listening Distance with Set Max Range.

Ensure Proper Gateway Placement

Placing the Gateway centrally is important for several reasons:

  • Balanced Signal Distribution:

    • By placing the Gateway centrally, the RF signals can be evenly distributed throughout the entire area.

Additional Guidance

  • Regular Maintenance:

    • Check the Anchors, Mobiles, and Gateways for any physical damage. Damaged hardware can negatively affect calibration or positioning.

    • Troubleshooting Tips:

      • If you are experiencing issues, unplug the Gateway and reboot the system by closing and reopening the Config Tool.

Review the Calibration Steps

Taking proper steps and following the instructions closely is important for a successful calibration. Please read our help article on how to calibrate your system: How to Calibrate Your Positioning System.
