Data record instr.ground-resistance-tester.variants

Verified 2026-10-27 Confidence: High

A three-terminal instrument suffices for measuring the resistance of a ground electrode, while a four-terminal instrument adds soil resistivity measurement and the higher-resolution readings needed for the slope method and for resistivity surveys over large areas.
