Measurement system software

1. The system software model is VSM-100C&D, which can directly set system parameters and display data directly;

2. The suffix of the original data file is 13D, which is directly stored in the computer to facilitate subsequent processing. Excel and Origin can be used to directly process the data;

3. A variety of measured curves and characteristic parameters can be displayed on the computer screen. The software can select data at will, partially zoom in, translate, smooth the curve, and can also be output and printed on a laser printer; it can also be printed by other Processing on general drawing software;

4. It can automatically measure the magnetization curve, hysteresis loop, fast MH loop, and background curve; when the demagnetization factor and sample density are known, the magnetic characteristic curve of the VSM open circuit sample can be automatically converted into the substance itself ( (Ie closed circuit sample) magnetic measurement curve;

5. The software can simultaneously calculate the curve parameters under the international unit system and the Gauss unit system (saturation magnetic moment/saturation magnetization/ratio saturation magnetization, residual magnetic moment/residual magnetization, coercive force, intrinsic coercive force, rectangular Coefficient, maximum magnetic energy product, loop area).
