The low-μ indicator is used for testing the relative magnetic permeability of weights. This paper presents a simple method for verifying the Low-Mu indicator standard inserts value, using a simulation of the weights by a coil standard of magnetic flux density of known length, number of turns and current value through the coil. The results of measurements of the set of standard inserts and the measurement uncertainty are also discussed. The method presented here can be used for standard inserts with a susceptibility value of up to 0.2 with expanded uncertainty of 8%.
