The Portable DC Winding Resistance Tester is an innovative product with a compact design, hand-held operation, and enhanced portability for easy carrying.This instrument is not only suitable for measuring transformers, mutual inductors, reactors, and other inductive test products, but also for testing copper bars, conductors, switch contacts, and other resistive components. The tester offers fast testing speed and high accuracy. Functional Characteristics 1.Adaptive Power Supply: Supports both lithium batteries and 220V AC supply. A single charge allows for the continuous testing of the DC resistance of hundreds of transformers. The testing process is simple and convenient. 2.Adjustable Output Current: The output current has six selectable grades, with a maximum of 10A and a maximum output voltage of 25V. The current is automatically selected for convenience and speed. 3.Wide Measurement Range and High Accuracy: Measurement range from 500 µΩ to 50 kΩ with high precision. 4.Three-Phase Automatic Testing: The instrument can perform three-phase testing automatically, and the three-phase imbalance rate is calculated automatically. 5.Resistance Temperature Conversion: Includes a resistance temperature conversion function and can be equipped with a wireless temperature measurement module to measure the ambient temperature in real-time, ensuring the accuracy of the resistance measurement. 6.Comprehensive Protection Functions: Equipped with multiple protection features, such as back EMF protection, broken line protection, power-off protection, and over-heating alarm.
