Winding Resistance Meter 15Amps, 2 Channels Rack
WR14R
Description
Raytech Digital Winding Resistance meter WR14 R is the rack mount version of the WR14. They are designed for high degree of accuracy for the 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 R applies 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.
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.
