The Raytech WR-50-12 features a simple push and turn button operation from Micro Junior and charges inductive loads up to 1500 Henry. It provides heavy duty protection circuitry with fully remote operation and control with an external PC.


The Raytech WR-50-12 Digital Winding Resistance Meter is the enhanced version winding resistance system with a most advanced demagnetizing circuit. It is designed for high degree of accuracy for the measurement of very low resistance of any inductive loads. Its unique measure technique incorporates a high precision measurement circuit, a unique power source and the fastest discharge unit on the market. The WR series of instruments apply a preset current level, selected by the user, from 0.025A to 50A. The results are reported on the easy-to-read color LCD display and can be stored or printed. The WR50 is a compact, lightweight system, designed with its own rugged waterproof field case. It has advanced protection upon powering on the system by initializing itself with a self-calibrating, circuit checking sequence. If any problem is detected during initialization or operation, the operator immediately will be notified. The system constantly monitors the condition when turned on. The WR series have extensive protection built in to the circuitry.
