calibration/accuracy of current sensor.

I've just built a 72"yak with a 6s electric setup. I've put a whole bunch of sensors in it to. Gps, vario, esc temp, servo current monitor, 200A current sensor, spc voltage and main battery voltage.

I spun the motor up on the ground and the Tx is showing 83A at full throttle. I also had a GT Power watt meter plugged in and that said 120A.

That's a 30% difference. Is there any way to calibrate the current sensor? its not really useful when its that far out.

There isn't a way to calibrate the sensors, the only thing I can think is maybe there is something wrong with the current sensor.
