First thing would be reading the board manual at https://www.analog.com/media/en/technical-documentation/user-guides/UG-364.pdf , then making it work with simple impedances like resistors and capacitors, getting comfortable with calibration, etc. Once you get a good grasp of how the board and software is operating you can move to measuring liquids with IDEs, which is a complicated subject of its own.
okay thank you so much. i have another question. can this board used as Electrical impedance spectroscopy (EIS) instument?
Technically the chip is the EIS device. Of course it has limitations, for example: frequency range, if compared to general-purpose lab EIS devices that cost $$$.
Oh i see. Thank you sooo much. Theres so much i meed to learn about electrical engineering. Its hard. But ill try my best. Thank you so much
