The TR-Mark II R is the 19" Rack
Mount version of the legendary TR-Series which has quickly become
recognized as the World's most advanced Three Phase Transformer
Ratiometer.
The TR-Mark II R fully automatic measures
Turns Ratio, Voltage Ratio, Excitation Current, Phase
Relationship, and Phase Displacement.
A single hook-up to the transformer is all that
is needed to run a complete series of tests because all
connections of various transformer configurations are accomplished
internally.
The Mark II R system does not require any
charts or calculations for testing. The system can test more
combinations of transformer configurations than any other system
making it the most versatile and easiest to use system
available.
The Mark II R tests one of the widest
ratio ranges available (0.8....13,000) and has the highest
accuracy of any Automatic Three Phase Ratiometer (0.08%).
