External Bias
The 2 Volt DC bias available internally (see the Measurement Keys and
Indicators section) is usually adequate for polarizing electrolytic capacitors.
However, it is possible to externally connect a fully floating power supply (or
battery) to give a bias voltage of up to 50 Volts DC maximum.
The external DC bias must be connected to the MZ-805 and DUT as
shown in the diagram. The High Drive, High Sense, Low Drive and Low Sense
connections to the MZ-805 are made using the optional interface adapter AD-
805 which inserts into the Kelvin connectors on the top of the instrument.
The BNC connectors on the interface module are marked with the signal
names. Connect to the power supply and DUT using screened cables, e.g.
miniature coaxial cable, but leave the screens unconnected at the remote end.
CAUTION Always observe the correct polarity when connecting

capacitors; failure to do so may result in damage to the
DUT and possible user injury.
