It is designed for a high degree of accuracy for the measurement of very low resistance of any inductive load. The results are reported on the easy-to-read color LCD display and can be stored or printed.
Unique Measuring Technique: This newly designed technique of measurement incorporates a high precision measurement circuit, a unique power source, and the fastest discharge on the market.
Operation: The WR series of instruments apply a preset current level, selected by the user, from 0.025A to 50A.
Compact Design: The WR50 is a lightweight system, designed with its own rugged waterproof field case.
Advanced Protection: Upon powering on, the system initializes itself with a self-calibrating, circuit checking sequence. If any problems are detected during initialization or operation, the operator will be notified immediately. The system constantly monitors the condition when turned on. The WR series has extensive protection built in to the circuitry.
