The DO8000 is the ideal measuring instrument for transformer
and other inductive windings. The advanced power supply ensures
that measurements are fast and stable. The two measuring channels
permit both primary and secondary windings to be measured and displayed
at the same time, and with the addition of the internal timer and
data logger cooling curves can be measured without problems.
