The DTR Model 8510 digital transformer ratiometer is the second generation of the Model 8500. Features include PT/VT from 0.8000:1 to 8000:1 and CT from 0.8000 to 1000.0 (auto-ranging), the ability to store up to 10 primary/secondary nameplate voltages to use in comparing test results, storage capacity for up to 10,000 test results, and a DC test mode that eliminates error due to magnetic buildup. CE-approved, testing is performed by exciting the primary and reading the secondary, which the company says provides safer conditions for the user on step-down transformers. DataView software is included.
