Abstract
This note describes an ac bridge for measuring the series components of high‐impedance metal‐liquid interfaces. The real and imaginary components of the impedance may vary over a wide range. All frequency‐independent residual error‐introducing elements in the measuring circuit may be balanced out through a single square‐wave initial balance step. This allows accurate, direct‐reading measurement of the unknown. The bridge design is based upon superposition of frequency‐independent bridge circuits.This publication has 2 references indexed in Scilit:
