What’s Precautions if do Proton Precession Magnetometer Gold Geophysical Equipment Gradiometer survey work?

1. Before the construction in the field, it is necessary to accurately check the clocks of the base station and the mobile stations so that the clocks of each mobile station and the base station are consistent (the survey modes must also be kept consistent), because the system performing the daily correction is synchronized through the clock. WCZ-3 might select GPS automatically calibration time or manually set time.

2. During start-up, survey of the base station should be started firstly. To stop working, stop survey of the base station after all mobile stations are stopped.

3. The base station should choose where the earth's magnetic field is stable and where the magnetic field gradient changes very little. Any possible interference source should be avoided. For example, fields of vehicles on highways or railways, power lines, power stations, communication stations, etc. are unstable. These positions should be avoided. The base station should also be set in a place where is unlikely to be passed by persons and animals.

4. For best observations, the probe must be kept away from magnetic material. During the measurement process, the operator should remove the magnetic substances on the body (such as belt buckles, screwdrivers, pens, knives, etc.), Normally, as long as the distance between the probe and the operator and the instrument is greater than the length of one arm, the impact on the measurement results can be avoided.
