4 CONNECTIONS

Component Connections
The leads of the Device Under Test (DUT) are inserted in the Kelvin
connectors on the top of the instrument. Axial components can be inserted into
the adaptors supplied, or on the AD-805 and Kelvin Clip set CC-705, which
themselves are inserted into the Kelvin connectors. Both forms of connection
provide true four—terminal contact to the DUT to ensure accurate measurement
of low impedance components.
The leads of radial components can be pushed directly into the spring—
loaded connectors.
opened by pressing down on the connector actuators.
Similarly, the axial adaptors can be inserted by pushing directly into the
main connectors; adjust the position of the adaptors to suit the lead and body
length of the axial DUT.
Ensure the contact surfaces of the Kelvin connectors are free from
contamination. If in doubt, refer to the Maintenance section.
Surface Mount Components
Plug the interface of the optional surface mount tweezers AD-806 into the
Kelvin connectors. True four—terminal connection is maintained at the tweezers.
Remote Connections
A remote test jig can be connected via the BNC connectors on the
optional interface adapter AD-805 which inserts into the Kelvin connectors on
the top of the instrument. The connectors are labelled High Drive, High Sense,
Low Sense and Low Drive. The screens of the Drive coax cables should be
connected together at the remote end and connected to the screen and case of
the external jig. The screens of the Sense leads should be isolated both from
each other and from the jig screen.
Whilst leads of up to 1 metre are unlikely to present problems, the leads
to an external jig should be kept as short as possible and the accuracy of
measurements checked at all test frequencies and over the range of values
being measured before being relied upon.
