Product Introduction
1. High-Precision Digital Upgrade for DC Bridges
Our Transformer DC Winding Resistance Tester is a next-generation replacement for traditional DC single and double bridges (Kelvin/Wheatstone bridges). Utilizing advanced switching power supply technology, this unit delivers measurement speeds over 100 times faster than manual bridge methods, making it the ideal tool for rapid induction-load testing.
2. Sunlight-Readable Dual LCD Display
Engineered for superior field visibility, the device features a specialized dual-LCD interface:
Primary Display (4.5 bits): Provides high-resolution measurement results.
Secondary Display (3.5 bits): Shows real-time ambient temperature or current values. Unlike standard LED screens that wash out in bright environments, our high-contrast LCD ensures excellent readability even under direct sunlight.
3. Advanced Safety with Auto-Arc Suppression
Safety is paramount when testing inductive loads. The instrument is equipped with an automatic arc suppression and discharge function, protecting both the operator and the equipment from high-voltage back-EMF (Electromotive Force) during the disconnection process.
4. Robust Anti-Interference & Reliable Accuracy
Designed for harsh electrical environments, this digital ohm meter offers exceptional anti-interference capabilities. It provides stable, repeatable, and high-precision data even in high-voltage substations. The unit is characterized by its compact size, low power consumption, and long-term reliability.
5. Field-Optimized Portability (AC/DC Dual Use)
Built for the mobile engineer, the tester includes a built-in 12V rechargeable battery pack. With AC/DC dual-power functionality, it offers maximum flexibility for on-site inspections where external power sources may be limited. Its lightweight and durable design ensures it can withstand the rigors of field transportation.

Product Feature And Application
High-Precision Transformer DC Winding Resistance Tester (2A) – Key Advantages
1. Rapid Measurement & Accelerated Core Saturation
Designed for speed, the instrument delivers a maximum output current of 2A. It is specifically engineered to overcome current inertia in large inductive loads, significantly accelerating iron core saturation. This reduces charging time and allows for measurement speeds hundreds of times faster than traditional manual bridges, making it ideal for high-efficiency field inspections.
2. Exceptional Accuracy with Kelvin 4-Wire Technology
By integrating advanced four-terminal (Kelvin) measurement and constant current source technology, the unit maintains a rock-solid charging current even under heavy inductive loads.
Anti-Inductive Stability: Built-in protection against back-EMF ensures stable readings and protects the circuitry.
High Repeatability: Utilizing premium imported components, the tester ensures superior accuracy and consistent repeatability for long-term condition monitoring.
3. Ultra-Wide Measurement Range
This versatile digital ohmmeter covers a broad spectrum of testing requirements, with a measurement range spanning from 1μΩ to 2kΩ. This wide dynamic range allows for the precise testing of everything from small coils to massive power transformer windings.
4. Versatile AC/DC Dual-Power & Field Portability
Engineered for the mobile engineer, the instrument features an integrated rechargeable battery pack for AC/DC dual-use. Its ruggedized, lightweight portable design ensures ease of transportation and reliable operation in remote substations or areas with limited power access.
