Foxboro, Mass., December 16, 2010—AEMC's new digital transformer Ratiometer DTR, Model 8510, is a second-generation instrument
incorporating the latest technology, improving on its’ highly successful predecessor, the Model 8500. It offers straight-forward operation, high accuracy, data storage and provides automatic test result documentation.

Features Include:
- Ratio testing: PT/VT from 0.8000:1 to 8000:1 and CT from 0.8000 to 1000.0 (auto-ranging);
- Tests performed by exciting the primary and reading the secondary; provides safer conditions for the operator on step-down transformers;
- Continuity test indicates open or loose (high resistance) terminal connections;
- Dc test mode eliminates errors due to magnetic build up;
- Stores up to 10 primary/secondary nameplate voltages to use in comparing test results;
- Displays ratio, test current, winding polarity and deviation from nameplate voltage or ratio;
- Stores up to 10,000 test results;
- DataView software included, which allows configuring the instrument, downloading stored measurements and printing of test results in a report format. Display warns of incorrect lead connection, reverse polarity, open and short circuits; and
