Exploring the scalings of error field locked mode in present tokamaks is of significance on the application of engineering design and steady state operation analysis for future reactors. Systematic investigation on the scalings of error field locked mode has been implemented in EAST in recent years. With multi-parameter scalings, the underlying physics of toroidal field and q95 scalings of error field locked mode has been clarified. These results have been included in ITPA MDC-19 reports and applied in extrapolation of error field tolerance in CFETR. The Results have been published in Nuclear Fusion.

Toroidal field scalings of error field locked mode in EAST are consistent with the theory and simulation
