Abstract In order to improve the management of magnetic prospecting, ensure the quality of field work and adapt the management to the development of science and technology, especially to the improvement and enhancement of magnetic instruments, it is necessary to make timely revision of the relevant technical regulations or operational standards, which should agree with the actual conditions. It means that the regulations should be clearly determined and easily executed by subordinate production units. This paper discusses the safety separation distance between probes during the noise testing of magnetometers before the operation mentioned in "Technical Regulations of High Precision Grounded Magnetic Measurement" based on certain detailed field experiments. In combination with related technical regulations and the requirements of the textbooks as well as special test results, the authors propose some suggestions for revising the above regulations after the comparison and analysis of the results.
