Data record instr.winding-resistance-meter.core-saturation

Verified 2026-10-27 Confidence: High

A winding resistance meter injects enough direct current to drive the transformer core toward saturation, which reduces the effective inductance of the winding and lets the current stabilize sooner; too low a current gives noisy, inconsistent readings and too high a current heats the winding, so the current is kept in a band expressed as a fraction of the rated winding current.
