Test principle 2.1 Principle block diagram The test principle block diagram of DX-9700HC Hard alloy test system is shown in Figure 2.1. 2.2 Measurement process The whole measurement process is: the computer sends the excitation current signal to the DX-9700HC excitation power supply through the data acquisition card, and controls the measurement process at the same time. The excitation signal usually used is an integral period waveform which is approximate to triangular wave. Under the action of the excitation current, the electromagnet produces...
