NRZDC-5A DC resistance quick test instrument is an ideal instrument for measuring the DC resistance of transformer windings, high and low voltage cables and large power capacitors and inductors. It adopts a brand-new power supply technology and has the characteristics of rapid measurement, small size, convenient operation and high measurement accuracy.
The NRZDC-5A is a compact, high‑accuracy direct‑current resistance tester designed for measuring transformer windings, power cables, and large inductive loads. It uses a four‑wire method with a programmable constant‑current source and a high‑precision A/D converter to provide fast, reliable resistance readings.
The manual describes the instrument’s panel layout, connection methods, data storage and printing functions, safety precautions, and troubleshooting steps, enabling users to quickly set up measurements, store up to 255 results, and print them with the built‑in mini printer. This manual is written in Chinese.
