-
The system software model is VSM250, which can directly set system parameters and display data intuitively;
-
The original data file has a suffix of 13D and is stored directly in the computer to facilitate subsequent processing. You can use Excel and Origin to process the data directly;
-
Various measured curves and characteristic parameters can be displayed on the computer screen. The software can arbitrarily select the data, partially enlarge, translate, smooth the curves, and can also output and print on a laser printer; it can also be used by other Processes on general drawing software;
-
It can automatically measure the magnetization curve, hysteresis loop, fast MH loop, heating curve, cooling curve, temperature rising and cooling curve, temperature control curve, magnetization curve, hysteresis loop and fast MH loop at the set temperature. and background curve; when the demagnetization factor and sample density are known, the VSM's open-circuit sample magnetic characteristic curve can be automatically converted into the magnetic measurement curve of the material itself (i.e., the closed-circuit sample);
-
The software can simultaneously calculate the curve parameters (saturation magnetic moment/saturation magnetization/specific saturation magnetization, residual magnetic moment/residual magnetization, coercive force, intrinsic coercive force, rectangular shape) under the International System of Units and Gaussian Unit System—coefficient, maximum magnetic energy product, loop area, Curie temperature).
