How is the prompt of ＂Measured value is inaccurate＂ on WCZ-2 proton magnetometer
1) Estimated magnetic field and the actual magnetic field are quite different.
2) Sensor is not well connected. Please check whether the sensor cable is short-circuited or broken.
3) Sensor is open-circuited. Check the impedance of the sensor, nominal impedance should be about 12ohm.
4) Noise is too high in that thunder or power line exists.
