Magnetizing Voltage Range: Adjustment range for power output for sensor.
Magnetizing Waveform: Sine for standard measurement and triangle for special purposes
Magnetizing Frequency Range: Sensor performance optimization
Analyzing Filter Range: Penetration depth of signal depends on analyzing frequency range. Lower frequency range means deeper penetration depth
Oscilloscope: For visualizing signal quality
