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.

Firmware WR (Old version)
Firmware
2.7.12.0

This Firmware is valid for the following products:
WR14, WR14 R, WR50-1x, WR50-1xR, WR100-12R, WR100-13R
This firmware is suitable for the older instrument (with the CPU model: NetDCU), for serial numbers less than 350-000. These insruments can work with newer firmware but it is slow and we recommend to use this firmware version instead.
