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 Battery Voltage
If you find the voltage is not correct, Enter the voltage 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.
