Following on the heels of the very talked-about DJI Mini 3 Professional is its successor, the Mini 4 Professional.
With its revolutionary gimbal that permits the digital camera to bodily shoot vertical footage and the omnidirectional impediment avoidance system, it’s best for these new to flying drones, social media and solo content material creators, journey bloggers, and extra.
To make sure the DJI Mini 4 Professional is functioning appropriately and constantly, there could also be instances within the close to future when varied necessary calibrations needs to be made.
This text and the included YouTube video will briefly talk about varied points which will come up throughout the Gimbal, IMU, and Compass, and function a step-by-step information for calibrating your Mini 4 Professional Gimbal, IMU, and Compass.
We’ll now have a look at why these varied calibrations would should be carried out, adopted by find out how to calibrate the Gimbal, IMU, and Compass utilizing the DJI Fly app.
Gimbal Calibration
For these unaware, the gimbal on DJI drones has two particular functions:
- Serving as a bodily attachment level for the digital camera to the drone
- Offering 3-way digital camera stability
The gimbal is used to make sure clean and degree video footage and degree photographs.
If the gimbal on the DJI Mini 4 Professional is off-center or barely misaligned whereas in use, it might trigger additional work in post-processing software program to get corrected (i.e., DaVinci Resolve, Last Lower Professional, Lightroom, Photoshop, and so forth.)
As a result of gimbal calibrations are associated to the drone’s digital camera, not like the IMU and compass calibrations, gimbal calibration doesn’t have an effect on how the Mini 4 Professional flies.
The gimbal does a self-check every time the Mini 4 Professional is turned on.
Nonetheless, if you happen to discover that the digital camera in your Mini 4 Professional has bother staying degree (uneven horizon) or wanders often throughout flight, then it’s time to manually calibrate the gimbal by way of the DJI Fly app.

To calibrate your Mini 4 Professional’s gimbal:
STEP 1: Whereas the Mini 4 Professional is off, take away the gimbal cowl.
STEP 2: Whereas on a flat floor, energy on the DJI RC 2 or RC-N2 that you just frequently fly your Mini 4 Professional with.
STEP 3: Energy on the Mini 4 Professional. After the DJI RC 2 or RC-N2 connects to the Mini 4 Professional, it might mechanically swap over to Digicam View. If you’re not dropped at the Digicam View, faucet GO FLY.
STEP 4: As soon as in Digicam View, go into the Fly app menu/choices by tapping the three dots within the higher right-hand nook.
STEP 5: Find and faucet the Management Tab. Scroll down till you see Gimbal Calibration. Subsequent to that press the arrow to the precise and select Auto to mechanically calibrate the gimbal.
Alternatively, you may select to manually calibrate the gimble. In the event you select Handbook, it is possible for you to to outline the Horizontal and Yaw values to get your horizon degree.
That is useful for when within the air and that you must calibrate on the fly.

IMU Calibration
The job of the Mini 4 Professional’s Inertial Measurement Unit (IMU) is to make sure that the Mini 4 Professional is degree and secure within the air. It accomplishes this by monitoring the drone’s velocity, angle, power, and angle.
To observe these areas, the IMU continually checks the Mini 4 Professional’s accelerometer, barometer, gyroscope, and thermometer. If any of those programs are malfunctioning and never corrected, the Mini 4 Professional might:
- Tilt whereas hovering
- Have issue remaining regular and secure within the air, and/or, in uncommon circumstances,
- Show indicators of issue cooling down
By calibrating the Mini 4 Professional’s IMU, ideally when prompted, you may cut back sensor errors and have an total higher flying expertise.
DJI suggests IMU calibration everytime you fly exterior of a 30-mile radius of your final flight and each 1,000 ft of elevation change.
Once more, that is the producer’s suggestion. Many drone operators don’t carry out these steps except wanted or prompted by the DJI Fly software program.

To calibrate your Mini 4 Professional’s IMU:
STEP 1: Whereas the Mini 4 Professional is off, take away the gimbal cowl. This can be sure that when the Mini 4 Professional is turned on, the motion of the gimbal is not going to be impeded.
STEP 2: Energy on the DJI RC 2 or RC-N2, whichever you utilize frequently. If utilizing the RC-N2, additionally launch your DJI Fly app.
STEP 3: Energy on the Mini 4 Professional. After the DJI RC 2 or RC-N2 connects to the Mini 4 Professional, it might mechanically swap over to Digicam View. If this doesn’t mechanically happen, faucet GO FLY.
STEP 4: As soon as in Digicam View, go into the Fly app menu/choices by tapping the three dots within the higher right-hand nook.
STEP 5: Find and faucet the Security Tab. Scroll down till you see IMU Regular. Subsequent to that, press Calibrate to enter the IMU Calibration course of.
STEP 6: Press Begin, then observe the prompts and transfer the Mini 4 Professional into the assorted positions as directed on the display.

Compass Calibration
The Mini 4 Professional’s compass is strictly what one would anticipate of an ordinary compass one would possibly convey on a hike. It’s an inside digital machine that helps the Mini 4 Professional know the place it at present is, location-wise.
Uncalibrated drones might fly erratically or ultimately crash because of a lack of management.
Due to this, drone producers, together with DJI, counsel a compass calibration be executed everytime you fly exterior of a 50-mile radius of your final flight (up from the 30-mile radius of the IMU) and each 1,000 ft of elevation change.
Many drone operators calibrate their drones solely when prompted. We suggest performing what works in your state of affairs.
When calibrating your Mini 4 Professional, be sure you are away from any metals or areas with sturdy interference. These areas embody most parking garages, as oftentimes, these are filled with structural rebar that might trigger interference with the calibration course of.

STEP 1: Whereas the Mini 4 Professional is off, take away the gimbal cowl.
STEP 2: Energy on the DJI RC 2 or RC-N2 with which you frequently fly your Mini 4 Professional. If utilizing the RC-N2, you’ll have to launch your DJI Fly app.
STEP 3: Energy on the Mini 4 Professional. After the DJI RC 2 or RC-N2 connects to the Mini 4 Professional, it might mechanically swap over to Digicam View. Faucet GO FLY in case you are not mechanically dropped at the Digicam View.
STEP 4: As soon as in Digicam View, go into the Fly app menu/choices by tapping the three dots within the higher right-hand nook.
STEP 5: Find and faucet the SAFETY Tab. Scroll down till you see Compass Regular. Subsequent to that, press Calibrate to start out the Compass Calibration course of.
STEP 6: Press Begin after which observe the prompts and transfer the Mini 4 Professional into the assorted positions as directed on the display.
