Hello, My name is Jinhwan

I know that how I can set the calibration of resistor from AN-1252.

For example Zmin=1k, Zmax=45K, I got the value of Rcal = 13K, RFB=670ohm from

formula of AN-1252. So, I could get the accurate value of resistor between the Zmin

and Zmax.

However, when I set Rcal = 13K, RFB=670ohm, I didn’t know the how to calculate

measurable range of capacitor. As I mentioned, in case of the resistor, I already know

the range of resistor.

If you have a time, could you explain how I can calculate measurable range of

capacitor between the Rcal=13k and RFB=670ohm. Although I looked at the AN-1252, I

didn’t know that.

Please help me.

I will wait for your answer.

Hi,

This is answered in the AN-1252. the impedance value depends on your capacitor value and your excitation frequency,
