Abstract

The method involves measuring an AC and determining a resistance as a function of a value of adjustable portion of a voltage, which balances a voltage drop and the value of the AC - The balance voltage used to calculate the resistance is measured by a voltmeter (10), which has a greater accuracy than that of a lock-in amplifier (9). A distance between the sensors (11,12) may be such as to be able to detect a voltage, which can be perceived by the instruments used.
