Data record `instr.low-resistance-ohmmeter.thermal-emf-cancellation`

Verified 2026-10-27 Confidence: High

A thermal electromotive force arises at junctions between dissimilar metals, including where the probes touch the test piece and where the leads join the instrument, and it grows as the temperature difference grows; the offset it adds to the sensed voltage is what the current-reversal compensation of a low-resistance meter removes.
