Abstract: The laboratoty earthing system is the basic element of laboratory design, which effectively guarantees the tester safety and the accuracy of data. Elaborate on the requirements and functions of the laboratory earthing system, and provides suggestions and technical support for the design, construction and rebuilding of the laboratory earthing system through the analysis and comparison of two earthing system. Finally, it was concluded that an independent earthing system could reduce the interfering signal in the circuit.

Key words: Laboratory, Earthing system, Interference, Scheme, Comparison
