INAV: Calibrate your current sensor accurately and safely

🔗 https://www.MrD-RC.com 🔗 https://www.patreon.com/MrD_RC In this video, we take a look calibrating your current sensor. I'm doing this with INAV in this video. But the principal is the same for other flight controller firmware, such as ArduPilot or BetaFlight. I have an older video on calibrating the current sensor. But that involved having a prop on the aircraft and spinning it. This method takes away the danger involved with that. Plus it has a smoother current draw, so readings are much more stable. The electronic load can be purchased from https://bit.ly/MrD_ElectronicLoad As I mentioned in the video. Have a hunt around, as you may well find it cheaper. Make sure to get the 180 Watt version. ✈️ Contents ✈️ 00:00 Introduction 01:10 The electronic load: Required equipment 02:27 Multimeter and current measuring cable: Required equipment 03:36 The flight controller and what I've set up so far 04:03 Checking the current sensor scale in INAV 05:21 The web page with the current sensor calculator tool 05:53 Setting up the tool 06:23 Getting things ready to take the readings 06:45 Calibrating the voltage scale 08:26 Connecting up to calibrate the current sensor 09:54 Taking the current readings and entering them in the tool 12:28 Calculating the results and setting the scale and offset in INAV 12:54 Verifying the new current sensor readings 14:23 Conclusion Thank you for watching this video.
