Data record instr.ground-resistance-tester.selective-method

Verified 2026-10-27 Confidence: High

In the selective (attached rod) method a current clamp around the electrode under test measures only the instrument's own test current flowing in that electrode, so a fall-of-potential measurement is made without disconnecting the electrode from the parallel grounding system.
