General Features of AC Hysteresis Graph (DX-2012M)
1. Testing sample varieties: hot rolling, cold rolling silicon steel materials, permalloy, amorphous and nm crystal.
2. Testing sample shapes: ribbon and chip open samples, annular, E and U closing samples.
3. Open circuit samples adopt EpsteinSquare to form a closed magnetic circuit, and can also select permeameter. The closing sample can be put under direct winding measurement, finished transformer can be also put under direct measurement.
4. Sample( iron core), magnetizing coil (N1) and measuring coil (N2) form a no-load transformer.
5. Non-inductive resistance is connected to magnetizing coil loop to determine magnetizing current and magnetic field intensity through the measurement of pressure drop on noninductive resistance, magnetic field peak value can be locked through digital feedback, and magnetic field lock precision 0.5%.
6. Magnetic induction density obtained through digital integration of coil measuring voltage, magnetic induction peak value locked through digital feedback, magnetic induction lock precision 0.2%.
7. Power source and sampling amplifier integrated into a casing with a simple interface: one RS232 interface connected to the computer, two-way voltage signal connected to A/D card.
8. Adopt voltammetry and digital integration to measure dynamic hysteresis loop, which can accurately measure dynamic magnetic characteristic parameters such as µa, d, Ps, Br and Hc, etc.
9. Automatic and continuous measurement up to 255 testing points, the testing time of every testing point is about 30 seconds, fixed-frequency, fixed Bm or fixed Hm optional in multipoint test.

2. Full automatic control, intelligent identification, and user intervention are unnecessary in the entire testing process.
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 the magnetic path of samples can be calculated according to the overall dimension of the samples.
5. The file system adopts a database format, and can directly print or output test results in Excel form.
6. Powerful file management functions: data saving, deletions and removal.
7. Data files contain complete sampled data, sample parameters, instrument parameters and testing schemes, adopt text format, and can be conveniently typed into other software.
8. Display I (t), U (t) and B (t) sampling waveform and B (H) hysteresis loop, and coordinate message at every data point on the curve.
9. The multipoint cluster can display B (H) magnetic hysteresis cycle cluster, B (H) magnetization curve, µa (H) permeability curve and Ps (B) damage curve, and can display coordinate message at every data point on the curve.
10. B (H) magnetization curve and Ps (B) damage curve measured under different conditions can be combined on one drawing for comparative analysis.
11. Set up upper and lower limits according to µa, Ps, Bm, Br, Hc and Hm, etc., qualify test results and determine through the color of the data table.
12. Support various models of printers, test reports accurately match printer sheets.
13. The print preview function can conveniently regulate the size and edge distance of the test report.
14. The test reports can be directly printed or generated as JPG image files.
15. JPG image files can be sent directly through E-mail, or saved into disk.
16. Test reports contain complete curve diagrams, test results, test conditions and sample parameters. To facilitate adding user mark and enterprise name.
17. Multiple unit systems are optional to satisfy the application habits of different users.
