= Calibrate barometric altitude sensor =

##include_Altitude_begin

~-!!! The following settings apply '''only''' to '''!FlightCtrl V3.0''' - Older !FlightCtrl versions can __not__ be calibrated !!!-~
<<BR>><<BR>><<BR>>

The barometric height sensor is required for automatic holding of the height of the !MikroKopter. <<BR>>
The sensor should be calibrated once. Thus, the sensor is working properly even under temperature fluctuations ~-(factor = x cm per °C)-~.

If the sensor is not calibrated, the copter can vary in height. <<BR>>

Recalibration of the height sensor is not usually necessary. <<BR>><<BR>>

'''INFO:''' Before the [[en/FlightCtrl_V3.0|FlightCtrl]] was delivered, the altitude sensor has already been calibrated.

== Calibration ==

{{{{#!wiki important

For calibration of the barometric height sensor, a heat source is required. <<BR>>
This can be e.g. a lamp or a hair dryer.

'''IMPORTANT: The heating MUST be SLOW.'''

}}}}

~+'''__The calibration is done in a few steps:__'''+~ <<BR>><<BR>>

||'''Step 1'''<<BR>><<BR>>The heat source (switched off) is positioned over the FlightCtrl.<<BR>>(~-You can remove the GPS if you want - then heating is a little faster.)-~||<:>{{ http://gallery3.mikrokopter.de/var/thumbs/intern/AltitudeCalibration/CalibrateAltitude-LampeAUS.jpg?m=1485942778 }}||
||'''Step 2'''<<BR>><<BR>>Connect the copter now with your computer.<<BR>>~-(via MK-USB or wireless)-~<<BR>><<BR>>Start the !KopterTool and power up the copter.<<BR>>~-(also switch on the transmitter)-~||<:>{{ http://gallery3.mikrokopter.de/var/thumbs/intern/AltitudeCalibration/Copter-PC.jpg?m=1485942779 }}||
||'''Step 3'''<<BR>><<BR>>Click the button "!NaviCtrl" in the !KopterTool.<<BR>>In the virtual window press the red arrow (left or right) and change the view to "Barometer". ||<:>{{ http://gallery3.mikrokopter.de/var/thumbs/intern/AltitudeCalibration/CalibrateAltitude-Step1.jpg?m=1485944116 }}||
||'''Step 4'''<<BR>><<BR>>When you see "Barometer" press the red arrow (up) under "(CAL)" and start the calibration.||<:>{{ http://gallery3.mikrokopter.de/var/thumbs/intern/AltitudeCalibration/CalibrateAltitude-Step2.jpg?m=1485944117 }}||
||'''Step 5'''<<BR>><<BR>>Now switch on the heat source.||<:>{{ http://gallery3.mikrokopter.de/var/thumbs/intern/AltitudeCalibration/CalibrateAltitude-LampeAN.jpg?m=1485942778 }}||
||The virtual display shows now "Warm up slowly" and the temperature increases slowly.||<:>{{ http://gallery3.mikrokopter.de/var/thumbs/intern/AltitudeCalibration/CalibrateAltitude-Step3.jpg?m=1485944117 }}||
||If this is to fast (it is to hott) you see the error "Heater off!"<<BR>><<BR>>Remove then the heat source and wait until the error is gone.<<BR>>If all is OK replace the heat source again with more space.||<:>{{ http://gallery3.mikrokopter.de/var/thumbs/intern/AltitudeCalibration/CalibrateAltitude-Step4.jpg?m=1485944118 }}||
||'''Step 6'''<<BR>><<BR>>If the heating is carried out correctly, an "Okay" appears after some time. in the lower right corner you see also a "save".<<BR>><<BR>>To save the calibration press the red arrow (up) under save.||<:>{{ http://gallery3.mikrokopter.de/var/thumbs/intern/AltitudeCalibration/CalibrateAltitude-Step5.jpg?m=1485944118 }}||

= Check calibration / manual adjustment =

In the window "Temperature settings" you can check the stored value and also change it.
<<BR>><<BR>>
~-!! If you change the value manually you can also have a negative effect during altitude hold - better use the automatic calibration!!!-~
