5. Calibration Process
◆ Start up the VSM equipment, and adjust the vibrating status;
◆ Preheat the VSM equipment;
◆ Zero Setting
◆ Installation of standard nickel ball sample;
◆ Adjustment of Nek area;
◆ Test of magnetization curve;
◆ Calculation of new calibration coefficient;
◆ Test the magnetization curve again;
◆ Compare the measured values of special saturation magnetization.
