Calibration Processes

Regardless of whether the DJI M30/T flight transmitter or DJI FlightHub 2 is used as the control method, the configuration menu contains two additional options not described above - calibration and parachute packing date. The parachute packing date option allows the user to see when their parachute is due to be re-packed (see the "" section for further information on re-packing timelines). The calibration option is used to re-calibrate the inertial measurement unit (IMU) of the PRS-M30.
In the event an IMU calibration is required, the following message will become visible on the main screen of the DJI M30/T flight transmitter or of DJI FlightHub 2. This is also indicated on the PRS-M30T itself by the status LED, which will flash yellow (see chart at top of "" section).
To properly calibrate the IMU, the PRS-M30 must be rotated through the six physical orientations, with a minimum of five (5) seconds spent in each orientation. Note that this actually results in seven (7) changes in orientation. The easiest way to accomplish this is simply to rotate the DJI M30/T through each orientation with the PRS-M30T attached, as shown below.
PRIOR TO ROTATING THE DJI M30/T, CHECK THAT THE PRS-M30 IS DISARMED BY ENSURING THAT THE PRS STATUS MESSAGE OUTLINED ABOVE READS "DISARMED".
After an additional thirty (30) seconds, a successful calibration will be signaled by the disappearance of the calibration warning from the main screen of either the DJI M30/T transmitter or DJI FlightHub 2. The LED status light will also change to green to indicate normal operations. If a successful calibration is not indicated, restart the DJI M30/T to re-pair the PRS-M30 with the DJI-M30/T.
Independently, the DJI M30/T may prompt a user that the on-board compass needs to be calibrated. In this case, a user shall simply follow the instructions displayed either on the DJI M30/T transmitter screen or in FlightHub 2. It is recommended that while calibrating the compass, the PRS-M30 be attached to the DJI M30/T to avoid changes to the DJI M30/T's magnetic field readings.
IF CALIBRATING THE DJI M30/T COMPASS WITH THE PRS-M30 ATTACHED, CHECK THAT THE PRS-M30 IS DISARMED BY ENSURING THAT THE PRS STATUS MESSAGE OUTLINED ABOVE READS "DISARMED".
It is also possible to calibrate the PRS-M30's IMU by using the "Calibrate Mode" function in AVSS Assistant. To access this feature, click on the “Calibration Mode” button to calibrate the PRS’s sensors. Note that if using this option, there is a 300-second time window to complete the calibration maneuver; otherwise, the calibration is automatically cancelled.
