Ratiometer stores 10,000 test results

The DTR® Model 8510 Digital Transformer Ratiometer supports a testing ratio from 0.8000:1 to 8000:1 for PT/VT and 0.8000 to 1000.0 for CT (autoranging). The tests are performed by exciting the primary and reading the secondary, providing safer conditions for the operator on step-down transformers. Continuity test indicates open or high-resistance terminal connections, and the DC test mode eliminates errors due to magnetic buildup.

The CE-approved ratiometer displays ratio, test current, winding polarity, and deviation from nameplate voltage or ratio and warns of incorrect lead connection, reverse polarity, and open and short circuits. It stores up to 10 primary/secondary nameplate voltages and up to 10,000 test results. DataView® software ships with the 8510 for configuring the instrument, downloading stored measurements, and printing test results in a report format.
