Data record instr.low-resistance-ohmmeter.four-terminal-source
Review status: Agent reviewed
A reference on impedance measurement published by the University of California, Berkeley physics laboratory describes the four-terminal technique as passing current through one pair of leads and measuring voltage on the other pair, which removes the error caused by the series impedance of the leads, and describes it as suited to low impedances.
