  • How is the prompt of "Measured value is inaccurate" on WCZ-2 proton magnetometer

    2016-12-25 23:24:48

    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 sens...[more]

  • What are the 3 working modes of proton magnetometer?

    2016-12-25 23:18:08

    The proton magnetometer, also known as the proton precession magnetometer (PPM), uses the principle of Earths field nuclear magnetic resonance (EFNMR) to measure very small variations in the Earths magnetic field, allowing ferrous objects o...[more]

  • Could I change mode of WZG-12A during measurement?

    2016-12-24 23:41:24

    I f survey mode is changed, relevant survey parameters and some Sample Parameters will be changed. Therefore, the survey mode cannot be altered during measurement; otherwise, parameters of lines will be in disorder....[more]
