Page 4: Safety Precautions
BEFORE APPLYING POWER Read this manual carefully before operating the system. The WR14 is battery operated, the WR50-12 and the WR50-13 are line operated. They operate from a wide range power input from 90 to 264Vac and 47…63Hz with automatic ranging. - Page 5 Because of the danger of introducing additional hazards, do not install substitute parts or perform any unauthorized modification to the instrument. Return the instrument to a Raytech service department for service to ensure proper operation and that safety features are maintained.

Page 10: System Details
The internal discharge circuit dissipates the stored energy in the transformer windings with a “Constant Power Discharge Circuit” that is unique to all transformer winding test systems. That is the reason why Raytech systems can discharge transformers more than 10 times faster than any other system on the market. -
