ACC kalibrieren

The ACC sensor is a three-axis sensor. With this sensor the current inclination of the MikroKopter is measured. In addition the automatic height control is supported.

If the sticks (for nick and roll) are centered, the copter automatically holds the balance.

For calibration, the copter must be absolutely straight. The more accurately the ACC sensor is calibrated, the better the copter holds the balance and the position.

Without this one-time calibration, the copter can not be started and an error message appears.

Recalibration of the ACC sensor is not usually necessary.

Note

Together with the ACC calibration the gyro calibration is also stored in the copter.
This we need for the BoatMode.





The calibration is done in a few steps:

Step

Example view (Mode 2)

Switch on the remote control and connect the copter with the battery.

Step 1

If the copter stands obliquely ...

http://gallery3.mikrokopter.de/var/thumbs/intern/ACC-Calibration/CalibrateACC_CopterNO.jpg?m=1486033038

... it must be aligned.

The easiest way is with a spirit level or circular level.

Step 2

On the remote control, move the stick for "throttle" and "yaw" to the following position. Hold this position for ~5-6 seconds !!

- Throttle => up

- Yaw => right

Step 3

The sticks can be released after you hear an acoustic confirmation from the copter.

The calibration is finished

ACC calibrate in flight

If you want to adjust the ACC more precisely, you can do this in flight.

For this type of calibration look for a sufficiently large field and it should be completely calm.

This calibration can be carried out with: a Graupner HoTT or a Jeti transmitter,
or with the KopterTool (a wireless connection between copter and computer is needed).

INFO

Before you can calibrate the copter during flight you have to calibrate the ACC once via the sticks (see above).

Without you can not start the copter!!!





HoTT

Step

Example view (Mode 2)

Switch on the remote control, connect the copter with the battery ...

http://gallery3.mikrokopter.de/var/thumbs/intern/sonstiges/Button-Baugruppe/Copter-FB-ON.jpg?m=1486035200

... and calibrate the Gyros.
(Throttle up + yaw left)

http://gallery3.mikrokopter.de/var/thumbs/intern/HoTT/Stick/MC32_CompassKali_2.jpg?m=1486457870

Step 1

On your Graupner HoTT transmitter open the
Text-Telemetrie (Link).
Here open the window "ACC calibration".

http://gallery3.mikrokopter.de/var/thumbs/intern/ACC-Calibration/HoTT-ACC/HoTT-TextDisplay-ACC-1.jpg?m=1486124919

Step 2

Set the trim for Nick and Roll now to "0".

Step 3

Activate the calibration.

Step 4

Function
- "AltitudeHold" -> ON
- "GPS" (PositionHold, ComingHome, CareFree)-> OFF

Start your copter and hover.

Step 5

With the button
- UP / DOWN (for Nick "N") and
- LEFT / RIGHT (for Roll "R")
you can now calibrate the ACC in smal steps. In the best case, the copter is hovering on the spot.
(a value around 512 for Nick / Roll is realistic)

http://gallery3.mikrokopter.de/var/thumbs/intern/HoTT/Button-SET-01/Button_SET_UD.jpg?m=1487085109http://gallery3.mikrokopter.de/var/thumbs/intern/ACC-Calibration/HoTT-ACC/HoTT-TextDisplay-ACC-5.jpg?m=1486124922http://gallery3.mikrokopter.de/var/thumbs/intern/HoTT/Button-SET-01/Button_SET_LR.jpg?m=1487085097

When you reach this, you finished the calibration
with "SET".

Step 6

Now land the copter,
and switch off the motors ...

http://gallery3.mikrokopter.de/var/thumbs/intern/ACC-Calibration/Copter_down.jpg?m=1487148900

... go down to "Save" ...

... and save the calibration by pressing "SET" twice.
