Calibration Process

Regardless of whether the DJI M3D/T flight transmitter or DJI FlightHub 2 is used as the control method, the configuration menu contains additional options not described above - calibration and RF binding. RF binding refers to a procedure used on older PRS systems and may be disregarded. The calibration option is used to re-calibrate the inertial measurement unit (IMU).

In the event a calibration is required, the following message will become visible on the main screen of the DJI M3D/T flight transmitter or of DJI FlightHub 2. This is also indicated on the PRS-M3DT itself by the status LED, which will flash yellow (see chart at top of previous section).

Calibration Warning for PRS-M3DT IMU

To properly calibrate the IMU, the PRS-M3DT 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 M3D/T through each orientation with the PRS-M3DT attached, as shown below.

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 M3D/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 within this timeframe, restart the DJI M3D/T to re-pair the PRS-M3DT with the DJI-M3D/T.
