Description
WR14 R
The WR14 R winding resistance meter is the same instrument as the WR14 but built into a 19″ rack housing.
Therefore, it can be used very well in test labs or be assembled into complete measurement systems. The WR14 R is a winding resistance system with a most advanced demagnetizing circuit. It is designed for a high degree of accuracy for the measurement of very low resistance of any inductive load. The WR14 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.
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.
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, the operator will be notified immediately.
