Description

Raytech's Digital Winding Resistance meter WR14 is the battery powered version winding resistance system with a most advanced demagnetizing circuit. It is designed for high degree of accuracy measurement of very low resistance of any inductive loads.

Unique Measuring Technique: This newly designed technique of measurement incorporates a high precision measurement circuit, a unique power source and the fastest discharge unit on the market.

The WR-14 apply a preset current level, selected by the user from 0.025A to 15A .

The results are reported on the easy-to-read color LCD display and can be stored or printed.

WR14 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 problem is detected during this initialization period, or during operation, immediately the operator will be notified.
