In a comment on his article about the Foxeer Arrow V2 FPV cam, Oscar Liang mentioned 'calibrating' the camera in order to rectify a situation where the battery voltage display is off by a factor of 10. (My camera, like some others, displays "5.2 V" instead of "15.2 V").

Does anyone know how to actuate a re-calibration?

Thanks,

1. make sure you are using the 'VSEN' pin is connected to your lipo battery? otherwise you will be getting the camera power supply voltage
2. make sure the voltage number is not partly hidden by the edge of the screen

Here is how to calibrate voltage:
