Calibrate Compass

Calibrate Compass

If the NaviCtrl is new you have to calibrate the internal compass (or the external one).
You can not start the copter and see an error warning in the telemetry when the compass is not calibrated.

The calibration

Please note

Calibrate the copter outside, far away from magnetic influences!

During the calibration you have to turn the copter completely around the axis.

The following applies: If you calibrate the compass precisely, the copter will fly perfectly.

If the copter is flying in circles (with activated function PositionHold and in an altitude above houses and trees), you better calibrate the compass new.

When you have problems after the calibration (e.g. an err22), a magnetic problem on your copter can be the problem.
Informations for the "magnetic error" can be found here:: MagnetError

The calibration will be done in 5 steps:

Step	Funktion	Beispielansicht / Funktion
Step 1 Initiate compass calibration	Nick down (and hold) then Throttle up + Yaw left (The Kopter beeps 1x)
Step 2 Start Calibration	Pull Nick down 1x (The Kopter beeps 2x and the clicking starts)
Calibration of the X-Axis (Nick-Axis)	The Kopter with the front (Arrow direction of the FlightCtrl) pointing to the South or North, then rotate the Kopter a couple times completely over the Nick-Axis until the buzzer stops with the clicking.
Calibration of the Y-Axis (Roll-Axis)	Rotate the Kopter by 90°. The clicking starts again. Rotate the Kopter a couple times completely over the Roll-Axis until the buzzer stops with the clicking.
Step 3 Finish the calibration of the X and Y-Axis	Pull Nick 1x down (The Kopter beeps 3x)
Step 4 Start calibration of the Z-Axis (Yaw-Axis)	Pull Nick 1x down (The Kopter beeps 4x and the clicking starts)
Calibration of the Z-Axis	INFO: Here it doesn't matter if the Kopter shows with the X or Y-Axis towards South (North). Rotate the Kopter a few times completely over the Roll- or Nick-Axis until the buzzer stops with the clicking.
Step 5 Finish the calibration of the Z-Axis.	Pull Nick 1x down The Kopter confirms it with 2 beeps

Now that the Kopter "beeped" 2x after a successful calibration that part is done.

Check the calibration

You can now check the calibration of the compass in the KopterTool or also with a suitable transmitter.

Please do this also outside, far away from magnetic influences!

Here you have to check two values:

MAG (or Field) = This should be around 100%
Inclination (Incl) = This should be nearly the same value as the one in brackets

IMPORTANT:
To see the right values you have to calibrate the Gyros first (throttle up + yaw left).
Without calibration you will still see 100% and no Inclination.

Check via KopterTool

Here you use:

a MK_USB or a wireless connection between Copter and Computer
+
you have calibrate the Gyros (throttle up + yaw left).

In the main window of the KopterTool click the button [NaviCtrl].

Under the virtual display klick the red arrow (left or right) until the window "Magnetic Field" displayed.

The value for "Field" must be around 100% and the value for Inclination around the value you see in brackets.
(If the value for "Field" is ~10%-15% higher/lower then 100%, recalibrate the compass)

Check via HoTT transmitter

You have calibrate the Gyros (throttle up + yaw left).
In the lower display of the Graupner HoTT transmitter you can open the text telemetry and check there the magnetic value.

press the ESC key longer
-> the TELEMETRY window opens
change to SETTING & DATA VIEW
press SET
-> RX DATAVIEW window opens
on the SET button press right until you see the last window with the text-telemetry
to change the view of "0m/s" to "MAG" press SET once.
