Adopted digital power source and A/D card instead of old analog power source, frequency meter, amperemeter, voltmeter and wattmeter.2. Perfectly match Windows system, easy to operate.3. Test Samples: hot&cold rolled silicon steel(oriented or non-oriented), permalloy, amorphous alloy and nanocrystalline.4. Sample shape: ribbon and chip open samples, ring, E&U shape etc closed-circuit samples.5. Open circuit samples adopt Epstein Square to form closed magnetic circuit, it can also select permeameter. Closing sample can be put under direct winding measurement, finished transformer can be also put under direct measurement.6. A non-load transformer included a sample core, a magnetizing turns(N1) and a measuring turns(N2).7. N1 connected non-inductive resistance, to define the magnetizing current by testing the descending voltage of the non-inductive resistance to get the field strength. Peak value lock feedback by digits, field lock accuracy is 0.5%.8. Get flux induction by digital analyzing the N2 voltage,Peak value lock feedback by digits, induction lock accuracy is 0.2%.9. Power source and sampling amplifier embedded in one case with simple interfaces: a computer-connect inferface RS232, two-way voltage signal connect to A/D card.10. Use voltammetry and DDA to test magnetic property like dynamic hysteresis loop, Ps, Jm, Hm, Ss, μa, loss angle, Br and Hc.11. Constantly test over 255 points, each one cost 30 seconds, fixed frequency, lock Bm or lock Hm modes optional.Software Functions1. Perfectly match Windows 7. English & English-Chinese version optional. Easy to operate.2. Lock Bm or Lock Hm oprtioal, multiple choices.3. Full-automatic operation. Intelligent auto-recognition.4. Measuring process in real time monitoring, can be suspended at any time.5. Automatic calculating. Be able to do results conversion according to temperature.6.
