Sorry for my english, and i hope u will understand me.
I have big problem with AD5933. I made PCB with AD5933 and AD8606 (the same as in AN-1252) and im trying measure body composition but its not work. I used Rfb = 220 Ohm and Rcal = 470 Ohm range 1, and when i measure only resistor or capacitor its ok but when i try to measure body with freq 50kHz the impedance is equal 5kHz (it should be 500Hz).
How can i calibrate device to have good result.
