Research of Influence Quantity on Mass Metrology
According to the measurement principle of magnetic parameter of weight, the influence of reading stability for measuring magnetism of weight is analyzed, and the key influence of reading stability is presented in the measurement process. The magnetism of weight is measured by the magnetic susceptometer with capacity of 5.1g and resolution of 0.1 mg. At the same time the change of environmental vibration at the laboratory and the fluctuating of ambient magnetic field are measured respectively. The experimental results show the fluctuating of ambient magnetic field that is the key influence parameter of weight magnetism measurement.
