Main Features

1. Apply to: soft magnetic ferrites, permalloy, amorphous, nanocrystalline, iron dust core, electrical pure iron and silicon steel etc.
2. Sample shape: ring, toroid, E and U closed circuit.
3. Closed circuit samples directly winded: samples, magnetized coils(N1), measuring coil(N2) form a non-load transformer.
4. Measure open-circuit samples need fixtures(solenoid or permeameter optional), its inner field is measured by a built-in magnetic potentiometer(optional).
5. Measure the field strength through testing the magnetizing current, field locking accuracy up to 0.1%.
6. Measure the flux density by electrical integrator, the integrator ZERO drift self-correcting by software.
7. Measuring method: analog ballistic and magnetic field sweep.
8. Adopt analog ballistic method to measure basic magnetization curve, can accurately measure magnetic characteristic parameters on magnetization curve: μi, μm, Bs, value μ of any point.  
9. Adopt analog ballistic method and magnetic field sweep to measure saturation hysteresis loop, can accurately measure magnetic characteristic parameters on hysteresis loop: Bs, Br, Hc and Pu. (This method is only used by Linkjoin, highly approved the accuracy)
10. Automatic demagnetizing function before μi test, demagnetizing with saturated AC 10Hz.
11. Select to test single parameter with analog ballistic method to save time, the time of every testing point can be set from 0.1 second to 0.9 second.
12. Adopt the B speed feedback, it can automatic regulate the density with the shape of sample magnetic characteristic curve, and curve can also be tested according to the testing point predefined by users.

Software Functions

1. Operate under Windows7, complied to Windows software restricts, easy to operate.
2. Automatic control, intelligent judgment, without manual operation all through the progress.
3. Sampling waveform and instrument status under real-time monitoring, and can be stopped at any time.
4. The effective sectional area and length of magnetic path of samples can be calculated according to the overall dimension of samples.
5. Automatic detecting sample condition, facilitate users to test unknown samples.
6. System adopts database format, can directly print or output test result to Excel form.
7. Various file management functions: data saving and deleting, remove all the data etc.       
8. Data files contain complete sampled data, sample parameters, instrument parameters and testing schemes, adopt text format, can be conveniently typed into other software.
9. Display B(H) magnetization curve, B(H) magnetic hysteresis loop or μ(H) permeability curve, and can display coordinate information of every data point on curve.
10. Support various kinds of printers, test report accurately match printer sheet. Print preview function, it can conveniently regulate the size and edge distance of test report. Test report can be directly printed, or generate JPG image file.
11. JPG image file can be sent directly through E-mail, or saved into disk.
12. Test reports contain complete curve diagrams, test results, test conditions and sample parameters, both Chinese and English format can be adopted to facilitate adding user mark and enterprise name.
13. Multiple unit system optional to satisfy the application habits of different users.
