These guides provide instructions on how to calibrate your gimbal and IMU for you Phantom 4 RTK. Use these instructions if you are receiving error messages pertaining to either of these systems. It is recommended to use the gimbal calibration if your gimbal motion is not responding well to inputs or is functioning incorrectly.

Instructions


Gimbal Calibration

“My gimbal is floppy! My camera isn’t steady during flight.” You may have an issue with your gimbal motor. Using the gimbal calibration may fix this, however you most likely are experiencing a hardware issue. Power cycle your drone and if this does not fix the issue, email support@firmatek.com for assistance.

Make sure your drone is on and connected to the controller before performing the gimbal calibration

To calibrate your gimbal:

  1. On your crystal sky display, navigate to the home screen and select the “Fly” button.

  2. Select the three dots in the upper right of the flight interface to open your settings.

  3. Select the “Camera” icon on the left hand side of the settings GUI and tap on the Auto Calibrate Gimbal button.

  4. Make sure your drone is on a flat surface and you do not move the drone during calibration. Press OK to begin.

  5. The gimbal will run through the calibration procedure and you will see the camera move around. Do not move the drone until the process is complete.

  6. Once the calibration is complete, power cycle your drone and proceed with your mission(s).

 

IMU Calibration

Remove your propellers before calibration. If the motors arm during calibration, having the propellers attached could be dangerous.

  1. On your crystal sky display, navigate to the home screen and select the “Fly” button

  2. Select the three dots in the upper right of the flight interface to open your settings.

  3. Select the “Drone” icon on the left hand side of the settings GUI and choose “Advanced Settings”

  4. Select IMU and Compass Calibration, and then choose “IMU Calibration”.

  5. You will now be asked to place your drone down on a flat surface in different positions. Pay close attention to the placements so that the calibration does not fail. Once placed, do not move the drone until instructed by the software.

  6. Once the calibration has run through all of the positions, it will complete. Power cycle your drone and proceed with your mission(s).
