ZXR-3A DC Resistance Tester with 3A Output Current and 1μΩ-2kΩ Range for Transformer Winding Testing
The ZXR-3A DC Resistance Tester is a high-precision instrument designed for transformer winding testing, featuring advanced switch power supply technology that delivers measurement speeds hundreds of times faster than traditional bridge methods.
Maximum output charge current up to 3A effectively compensates for current inertia in large inductors, accelerating core saturation and reducing charging time for rapid measurements.
Utilizes four-terminal measurement and constant current source technology with stable anti-sense capability and strong anti-interference characteristics for reliable, repeatable results.
Comprehensive resistance measurement from 1μΩ to 2kΩ covers diverse testing requirements.
Built-in rechargeable battery pack (12V) with AC/DC dual-use capability provides exceptional portability for field testing applications.
