2A 5A 10A 20A 40A Transformer Dc Winding Resistance Tester High Voltage Dc Tester

2A 5A 10A 20A 40A Transformer Dc Winding Resistance Tester High Voltage Dc Tester

Summary Introduction

GDZC-40 is an industrial grade DC resistance tester mainly used to measure the DC resistance of transformers and motor windings.

It is not only designed specifically for laboratories, but also for frontline electricians and maintenance personnel to quickly and safely complete testing on site.

Advantages

• Built-in protection circuits support overcurrent, overvoltage, and automatic discharge, ensuring safe operation after testing inductive loads.

• Strong anti-interference capability makes it suitable for use in substations, workshops, and other electrically noisy environments.

Features

• Uses a four-wire measurement method to eliminate lead resistance error, improving low-resistance accuracy.

• Offers five current levels: 2A, 5A, 10A, 20A, and 40A, allowing flexible adaptation to different resistance ranges.

• Includes a built-in thermal printer for on-site data printing.
