5. Calibrate the Airspeed Sensor
It is critical that you calibrate airspeed meter to ensure that it is working correctly, and ensure that it
is correctly zeroed.
After you start up APM on your aircraft you should wait at least 1 minute for your electronics to
warm up, preferably longer, and then do a pre-flight calibration of your airspeed sensor. Your ground
station software should have a menu for doing this, usually called “Preflight Calibration”. You need
to loosely cover your airspeed sensor to stop wind from affecting the result, then press the button.
The calibration will take a couple of seconds.
Choosing that action will re-calibrate both your ground barometric pressure and your airspeed
sensor.
Next you should check that your airspeed sensor is working correctly before takeoff. To do that you
should blow into the airspeed sensor and make sure that the "AS" airspeed sensor value in your
HUD rises as you blow into it.
6. Check the Two Batteries Voltages
If you find the voltages are not correct, Enter the voltages according to the hand-held volt meter
in the “Measured Battery Voltage” field, Press tab or click out of the field and the “Voltage Divider
(Calced)” value will update and the “Battery voltage (Calced)” should now equal the measured
voltage.
7. Check Before Flight
(1)Connect the internet and load
the map.
(2)The plane direction should be
same with its direction in mission
planner, if not, please calibrate
again.
(3)Check plane status, altitude,
voltage airspeed meter working
fine.
