I am trying to use AD5933 EVB to measure unknown resistors between 5-30 ohm.
I am confused about choosing the Z and RFB for first step (calibration)
Based on my understanding at first we should choose a resistor for this two and do the calibration and then remove Z; put our UNKNOWN resistor and do the measurement. Is that right?
But how we can choose a right value for Z and RFB?
