Following on the heels of the very talked-about DJI Mini 3 Professional is its successor, the Mini 4 Professional.
With its progressive gimbal that enables the digicam to bodily shoot vertical footage and the omnidirectional impediment avoidance system, it’s perfect 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 occasions within the close to future when varied essential calibrations ought to be made.
This text and the included YouTube video will briefly talk about varied points that 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 must be carried out, adopted by the way 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 digicam to the drone
- Offering 3-way digicam stability
The gimbal is used to make sure easy and stage video footage and stage images.
If the gimbal on the DJI Mini 4 Professional is off-center or barely misaligned whereas in use, it may trigger additional work in post-processing software program to get corrected (i.e., DaVinci Resolve, Closing Reduce Professional, Lightroom, Photoshop, and so on.)
As a result of gimbal calibrations are associated to the drone’s digicam, 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.
Nevertheless, when you discover that the digicam in your Mini 4 Professional has hassle staying stage (uneven horizon) or wanders sometimes throughout flight, then it’s time to manually calibrate the gimbal by 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 repeatedly 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 could routinely swap over to Digital camera View. If you’re not dropped at the Digital camera View, faucet GO FLY.
STEP 4: As soon as in Digital camera 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 proper and select Auto to routinely calibrate the gimbal.
Alternatively, you possibly can select to manually calibrate the gimble. Should you select Guide, it is possible for you to to outline the Horizontal and Yaw values to get your horizon stage.
That is helpful 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 stage and secure within the air. It accomplishes this by monitoring the drone’s velocity, angle, drive, and angle.
To watch these areas, the IMU consistently 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 may:
- Tilt whereas hovering
- Have issue remaining regular and secure within the air, and/or, in uncommon instances,
- Show indicators of issue cooling down
By calibrating the Mini 4 Professional’s IMU, ideally when prompted, you possibly can scale back sensor errors and have an general 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 until 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 make 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 employ repeatedly. 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 could routinely swap over to Digital camera View. If this doesn’t routinely happen, faucet GO FLY.
STEP 4: As soon as in Digital camera 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 varied positions as directed on the display screen.

Compass Calibration
The Mini 4 Professional’s compass is strictly what one would anticipate of a regular compass one may convey on a hike. It’s an inner digital machine that helps the Mini 4 Professional know the place it at the moment is, location-wise.
Uncalibrated drones could fly erratically or finally crash on account of a lack of management.
Due to this, drone producers, together with DJI, recommend a compass calibration be carried out 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 advocate performing what works to your scenario.
When calibrating your Mini 4 Professional, be sure to are away from any metals or areas with robust interference. These areas embrace most parking garages, as oftentimes, these are stuffed with structural rebar that might trigger interference with the calibration course of.

To calibrate your Mini 4 Professional’s compass:
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 repeatedly 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 could routinely swap over to Digital camera View. Faucet GO FLY in case you are not routinely dropped at the Digital camera View.
STEP 4: As soon as in Digital camera 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 begin the Compass Calibration course of.
STEP 6: Press Begin after which observe the prompts and transfer the Mini 4 Professional into the varied positions as directed on the display screen.
