D08000
RUGGED, PORTABLE DIGITAL TRANSFORMER
WINDING RESISTANCE OHMMETER
RESISTANCE MEASURING INSTRUMENTS
The DO8000 can measure and save more than 10,000 high
resolution test results, along with transformer nameplate data.
With its expansive memory, bright LCD screen, and concise
reports from its built in printer, this model sets the standard
in test equipment. The DO8000 can store hundreds of files,
each containing a virtually unlimited number of resistance
measurements, with tap and winding details, and several fields of
information about the transformer, its location, and the operator.
The file manager makes this information easy to locate, open,
view, and print past results. The DO8000 features 4.5 digit
resolution and 0.25% accuracy for precise measurement of
winding resistance. Input channels have sophisticated
sigma-delta D/A converters and notch filters to eliminate the
effects of substation noise.
