hi Team:
This is use my designed to test, using four electrodes;
1. The human body phase Angle test is inaccurate, test From 8KHZ to 256KHZ, increase frequency ,phase Angle also increase,but I test results are not directly related to the phase Angle and frequency；
2. The human body impedance increases from 8KHZ to 16KHZ, decreases from 32KHZ to 256KHZ,? why?
3. Test the pure resistance, the excitation current in the 8KHZ to 64KHZ range, use oscilloscope monitoring waveform and voltage amplitude change, voltage amplitude is basically the same, when the frequency switch to 128KHZ, 256KHZ voltage amplitude is significantly reduced?
could you pls help to support it?
